In September 2026, AMD Machines quoted a robotic laser welding cell for thin stainless steel parts. This page publishes that quote the way the buyer received it: price by line, equipment by model, scope, exclusions and schedule. Around it we've added the IPG Photonics application lab results and the vendor advice that drove every major decision. The buyer isn't named. Everything else is real.

It's a quote, not a delivered machine. We're publishing it because laser welding is the process buyers find hardest to budget, and the details that move the price rarely make it into public material: why the laser went up a power class, why a chiller showed up on the bill of materials, why nitrogen was the wrong shielding gas. For the broader picture of the laser processes we integrate, see our laser processing systems page.

A robotic laser welding cell is a guarded production machine in which an industrial robot guides a fiber laser welding head along the seams of fixtured parts, usually with an index table so one operator loads parts while the robot welds. The cell AMD Machines quoted here follows that layout.

How Much Does a Robotic Laser Welding Cell Cost?

This one costs $401,207, delivered to a US plant, installed and commissioned. Here is the breakdown from AMD Machines' September 2026 quote:

Quote line Price Share of total
Machine: robot, laser system, index table, frame, guarding and welding cabin, controls, safety, gas system, plus engineering, integration and factory trials $283,937 70.8%
Tooling: two part fixtures with locators, stops, clamps, valves and sensors $88,773 22.1%
Shipping and insurance to the US plant $14,717 3.7%
Installation and commissioning: two engineers on site for five days, travel included $13,780 3.4%
Total investment $401,207 100%

Payment terms: 40% with the purchase order, 35% at design release, 15% at approval at AMD's plant and 10% at final approval. The warranty is 12 months. Sales tax is extra.

For scale, AMD Machines' 2026 benchmark report puts a complex machine with several processes at about $300K and the average AMD project at about $500K. This cell lands between the two.

Four decisions drove most of the price in AMD Machines' quote:

  • The laser package. The source, welding head, chiller, process fiber and head accessories together are the largest purchased item in the cell. They cost more than the robot, the index table and the entire control system combined.
  • Welding without wire. It pushed the laser up a power class, which brought in a chiller. Details below.
  • Spot size. IPG's trials called for a large spot, which added a fiber coupler and a process fiber.
  • Tooling. At $88,773, tooling is 22% of the total: two four pan fixtures with 24 clamps, 24 valves and 60 sensors. Without filler wire, those fixtures have to hold every seam inside the gap limit.

What Did IPG's Laser Welding Trials Show?

Before AMD Machines issued the final quote, IPG Photonics ran application trials at its lab in Novi, Michigan. IPG asked for about 20 sample sets. The buyer sent samples of the style it considered more challenging and, at IPG's request, its preliminary welding fixture. The lab welded tacked parts with a 6 kW YLS-6000 source and a D50 head on a KUKA robot, with and without filler wire. From IPG's application report of September 8, 2026:

Result Without filler wire With cold wire (0.9 mm 308 stainless)
Laser power 1,500 W 1,000 W
Travel speed 17 mm/s (40 in/min) 17 mm/s (40 in/min)
Cycle time reported by IPG About 15 s per part About 15 s per part
Maximum gap along the seam 0.009 in (0.23 mm) 0.027 in (0.7 mm)
Top bead width on the cross section About 2.1 mm About 1.7 mm
Shielding gas in the lab Nitrogen Nitrogen (IPG noted it was ineffective)
Surface Clean, bright surface; minimal post processing Oxidized surface, harder to shield; may need post cleaning
IPG verdict Acceptable Acceptable

IPG's report gives the no wire limit as "300 microns (0.009 in)". Those two values don't match, so we design to the tighter one: 0.009 in (0.23 mm).

What AMD Machines took from the trials, and what matters for anyone budgeting a laser welding cell:

  • Speed beat the target. The application called for about 22 in/min. Both processes ran at 40 in/min, roughly 1.8 times that.
  • The textbook gap rule didn't hold. The common rule of thumb, including the one in our laser vs arc welding comparison, says autogenous laser welds start failing once the gap passes 10 to 15 percent of material thickness. That rule describes small spot keyhole welding. IPG ran the no wire sample as a conduction weld with a large spot and set the gap limit at 0.009 in. That's 0.23 mm on 0.8 mm sheet, about 29 percent of thickness. Get your number from trials on your own parts, not from a rule.
  • Lab tooling limits lab results. IPG could not weld the full seam because the rudimentary tooling provided for the trial let gaps open up, and it had no way to deliver shielding gas to the back side. A production fixture has to do better than the one in the lab.

Should You Laser Weld With or Without Filler Wire?

IPG recommended cold wire. The parts are stamped and formed, so some gap variation comes with them: prototype parts showed gaps up to 0.5 mm, beyond the 0.23 mm autogenous limit and inside the 0.7 mm cold wire window.

The buyer chose to weld without wire. That choice moves responsibility for the weld from the process to the parts and the fixture, and AMD Machines' quote spells it out:

  • The gap along the entire seam must not exceed 0.009 in (0.23 mm), based on IPG's trials.
  • Fixtures are designed around the buyer's approved drawings and production samples, and the buyer supplies parts consistent with them: edge straightness, flatness, trim condition and forming variation.
  • Weld defects caused by part geometry, fit up, material variation or surface condition are not a machine nonconformance.
  • If supplied parts can't hold the fit up, added testing, tooling changes or filler wire are quoted as a change order.

A fixture can locate and clamp a part. It cannot correct a part that is out of tolerance, distorted or inconsistent from lot to lot. Our welding fixture design guide covers the principles.

Choose When
No filler wire (autogenous) Parts hold the gap limit consistently, appearance matters, and you want minimal post processing and no wire feeder to maintain
Cold wire Gaps vary from part to part (up to about 0.7 mm on this material), and you can accept some oxidation and post cleaning in exchange for a forgiving process

For wire feeders, IPG had no brand requirement: Miller, Fronius and ABICOR BINZEL all build suitable units.

Which Shielding Gas Should You Use to Laser Weld Stainless Steel?

IPG's lab shielded both samples with nitrogen. The no wire sample came out clean and bright; on the cold wire sample the nitrogen was ineffective and the surface oxidized. Before building on those results, we asked which gas was used, because these parts are 430. IPG's applications engineer confirmed nitrogen and gave the rule: nitrogen works on all 300 series stainless, but 430 must be welded with argon, because nitrogen embrittles the weld and it will fail.

So every lab result above was produced with a gas the production cell won't use. The cell AMD Machines quoted is specified for argon, delivered through a regulator, flow control and a PLC controlled shutoff valve so gas flows only while the cell is welding, and the argon process gets proven during process validation at AMD with production parts. Argon is a consumable the buyer supplies. Back side shielding is not included, and root appearance depends on fit up and shielding.

The lesson: confirm the exact alloy with the engineer who runs the trial, not just on the request form, and check which gas produced the samples you're approving. For shielding practice by welding process, see our stainless steel welding guide.

How Do You Size the Laser, Optics and Chiller?

In AMD Machines' quote, five links in a chain moved the budget:

  1. Process power sets the source. The lab needed 1,500 W to weld without wire, so IPG specified a 2,000 W source for headroom. The first concept, built around filler wire, used a 1,500 W YLR-1500 with a D30 wobble head.
  2. The power class sets the cooling. At 2 kW, IPG required a chiller, an LC 120 water to air unit, which added a second piece of equipment to the laser package.
  3. Spot size sets the fiber. The trials called for a spot larger than the head's optics could produce on their own, so IPG added a fiber coupler and a 200 µm process fiber to the source. With 50 mm collimation and 300 mm focal length, the head images the fiber core at 6:1, a nominal spot of about 1.2 mm by our calculation (200 µm × 300 ÷ 50).
  4. Fiber length is a cost lever. IPG started from a 20 m process fiber and told us a shorter one could help the price. Specify the shortest your layout allows; our quote specifies 15 m.
  5. Lab power is not production power. The lab's source was 6 kW; the cell needs 2 kW. Size from the power the process used, not the power the lab happens to own.

Head options worth their cost:

  • CrossJet air knife. Deflects spatter away from the optics and extends protective window life.
  • HDMI camera on a 90° arm. For process viewing and weld path teaching. IPG recommends it during development: through the camera zoom you can see whether the robot path actually follows the joint.
  • Welding Head Alarm Monitor (WHAM). Supervises the condition of the head in real time and reports faults to the PLC.
  • Protective windows. Consumables. The quote includes two for startup. Budget spares as an operating cost; IPG sells D30 cover slides in packs of 25.

How Does a Laser Welding Cell Run in Production?

The cell is built for one operator and a two position index table, so loading and welding overlap:

  1. The operator selects the model on the HMI and adjusts the fixture if needed. Adjustable locators and fixed stops change sizes without reteaching the robot.
  2. The operator loads up to four pans and starts the cycle.
  3. The clamps close. Twelve part presence sensors and 48 clamp position sensors verify every pan; if one is missing or seated wrong, the cycle stops and the HMI shows exactly where.
  4. The table indexes the loaded fixture to the robot.
  5. The robot welds all four pans while the operator unloads and reloads the opposite fixture.
  6. The table indexes and the cycle repeats.

IPG reported a cycle of about 15 seconds per part in the lab, where the full seam couldn't be welded. AMD Machines' quote targets under 60 seconds per part, to be confirmed during process validation at AMD with production quality parts, because tacked samples on a lab fixture are not production.

Layout decisions that keep the cell serviceable: the control cabinet, laser source and chiller sit outside the weld zone; the robot and index table sit on dedicated welded steel bases tied to the main frame, so alignment survives a move; six heavy duty casters let the cell relocate as one unit; and the fixtures mount to a common interface, so tooling for other parts can be added later. A multicolor light tower and an operator indicator show when a fixture is ready to load.

What Safety Does a Laser Welding Cell Need?

The source is a 2 kW Class 4 laser emitting at 1,070 nm, invisible to the eye and hazardous directly or by reflection. AMD Machines' quote specifies:

  • a steel plate welding cabin around the robot and weld zone to contain reflections, as IPG recommended;
  • a barrier on the index table separating the operator load station from the weld zone;
  • one service door, which is also the cabin door, interlocked with both the laser and the robot;
  • SICK light curtains protecting the load station during index moves, plus two emergency stops and a safety relay monitoring the full circuit.

Be clear about what that is not. The cabin is not certified to IEC 60825-4 and has no viewing window; process viewing is through the camera. The buyer owns the laser safety program: the laser controlled area, the laser safety officer and personal protective equipment. In the US, ANSI Z136.1 is the usual reference for that program. Fume extraction is also excluded, even though IPG's guidance is that an enclosed welding cell needs it. See our notes on welding fume extraction and safety systems.

What Does a Laser Welding Cell Quote Leave Out?

Read the exclusions as carefully as the price. In AMD Machines' quote, the buyer supplies or buys separately:

  • Fume extraction for the welding cabin
  • Shielding gas (argon)
  • Back side shielding gas
  • A filler wire system (quotable separately)
  • Spare protective windows beyond the two startup windows; laser consumables are wear items outside warranty
  • The laser safety program: controlled area, laser safety officer and PPE
  • Electrical power, compressed air and site preparation
  • Sales tax

Sample parts are part of the buyer's scope too: 50 of each component with the purchase order for fixture design and process development, a production lot of 300 parts for validation at AMD, and more for site acceptance testing.

How Long Does It Take to Build a Laser Welding Cell?

AMD Machines quoted 20 weeks from purchase order to readiness for factory acceptance testing at its plant in Mexico, then shipping, installation and five days of commissioning on site with two engineers. The project runs through eight stages: commercial start, kickoff, design, manufacturing and factory validation, shipment preparation, installation, handover (training, safety audit and site acceptance test) and project closure.

Quoting takes time too. About 11 weeks passed between AMD Machines' first site visit and the final quote, including roughly three weeks in IPG's lab queue. If you need a laser cell by a certain date, start the trials early.

For context, AMD Machines' published lead times are as little as 6 weeks for simple custom machines and 24 to 26 weeks for complex systems, versus 40 to 42 weeks typical for overseas builders. More in our custom automation lead times guide.

AMD Machines' quote includes a full documentation package in English or Spanish: 3D and 2D files (delivered about two weeks after the machine, so final debug changes are captured), operator's manual, troubleshooting guide, technician's manual, ISO 12100 risk assessment, equipment specifications, installation guide, electrical and pneumatic diagrams, preventive maintenance plan, spare parts list and bill of materials.

What Should You Send an Integrator to Quote a Laser Welding Cell?

The fastest path to a firm number:

  1. Exact alloy, temper and thickness range. The grade decides the shielding gas.
  2. Drawings and a measured maximum gap on production parts, not prototypes.
  3. Your current process (plasma, TIG, spot) and what you want to fix.
  4. Cosmetic requirements for the weld face and the root.
  5. Cycle time target and annual volume.
  6. Sample sets for lab trials (IPG asked for about 20) and your current fixture if you have one.
  7. Supply voltage confirmed at the drop. The supply voltage on this quote changed twice before it settled at 208 V.
  8. Who owns laser safety and fume extraction.

Send us your part, alloy and gap data and we'll tell you whether it needs wire, what power class it lands in, what the fixture has to hold and what the cell will cost. Talk to an engineer. If your project is arc or spot welding instead, start with our welding automation page.

Laser Welding Cell FAQ

How much does a robotic laser welding cell cost?

In September 2026, AMD Machines quoted a 2 kW robotic laser welding cell for thin stainless steel at $401,207, delivered, installed and commissioned in the US: $283,937 for the machine, $88,773 for tooling, $14,717 for shipping and insurance and $13,780 for installation and commissioning.

What laser power do you need to weld 0.8 mm stainless steel?

In IPG's lab trials, 0.8 mm 430 stainless steel welded at 1,500 W without filler wire and at 1,000 W with cold wire, both at 17 mm/s (40 in/min) with nitrogen shielding. The production cell AMD Machines quoted uses a 2,000 W source for headroom and argon shielding.

How big a gap can laser welding bridge?

On this material, IPG's lab put the limit at 0.009 in (0.23 mm) without filler wire and 0.027 in (0.7 mm) with 0.9 mm cold wire. The no wire figure came from a large spot conduction weld; small spot keyhole welds tolerate less.

Can you use nitrogen shielding gas when laser welding stainless steel?

According to IPG Photonics, nitrogen is suitable for 300 series stainless steel. For 430 ferritic stainless, use argon, because nitrogen embrittles the weld.

Does a 2 kW fiber laser need a chiller?

In the cell AMD Machines quoted, yes. IPG specified an LC 120 water to air chiller for the 2 kW YLR source; at the lower power of the original concept, the chiller wasn't part of the package.
