Handheld fiber laser welding a stainless fillet on a fabrication bench

INDEPENDENT SOURCING PARTNER

Laser welding machine manufacturers, compared on one locked specification

This desk is for a tank integrator buying a robot weld cell, not a catalog of house-brand lasers. Send vessel diameter, wall grade, circumferential or longitudinal seam, quantity and US destination. We then collect factory wholesale quotations on that tank family so resonator, booth, robot, and the wire-feed synergic program list stay on separate lines.

What a laser welding RFQ should lock before factories price

A kilowatt plate does not tell a tank shop whether the first family belongs in a robot cell or a manual booth. Lock vessel size, seam class, GD&T datums, FAI coupons, the wire-feed synergic program list, and Incoterms so each factory answers the same tank brief.

Fiber laser source cabinet with cooling hoses labeled

Process and source class

State fiber, YAG or diode, continuous-wave versus pulsed, and whether stainless, carbon, or clad tank walls need a different absorption window. DFM notes on heat-affected zone and hoop distortion belong in the packet, not as later emails after the first quote lands.

Weld coupon with penetration section on an inspection bench

Joint, datum and GD&T

Name circumferential, longitudinal, or nozzle-to-shell joints, gap tolerance, and the datum scheme on the tank drawing. A fillet that looks closed on a shop photo is not acceptance until CMM points or section photos sit on the RFQ.

Robotic laser welding cell with seam tracker

Cell boundary and utilities

A robot cell and a manual booth are different purchases for the same tank family. List three-phase power, shielding-gas purity, chiller tons, extraction, and whether seam tracking plus the wire-feed synergic program list sit inside the factory line or as extras.

Landed-cost buckets

Keep Incoterm, destination, commissioning days, training seats, spare-kit contents, and the wire-feed synergic program list on their own lines so an EXW resonator is not treated as a delivered tank cell. This desk does not publish a savings percentage.

Specification groups to copy onto every bidder sheet

Use one tank-family revision. If a factory swaps a robot cell for a booth, or changes a synergic program set, mark that as an alternative, not a silent substitute.

Documents to request from candidate factories

ISO 9001, IATF 16949, AS9100D, ISO 13485 and ITAR registration belong to a named supplier and a named tank-cell scope. They are not credentials of this sourcing desk.

ISO 9001

Ask for the certificate, scope statement and expiry. Confirm the robot cell or booth family that would weld your tanks is inside that scope.

IATF 16949

Use when a tank or reservoir cell later feeds an automotive launch. Request PPAP capability statements as supplier evidence, not as our audit.

AS9100D

Use for pressure vessels or aerospace tanks. Ask whether NADCAP special processes apply to any downstream heat treat.

ISO 13485

Use if a tank shop also welds medical housings on the same RFQ. Confirm lot traceability and whether FAI plus material certificates ship with the first article cell.

Where buyers usually apply a laser welding cell

A tank integrator rarely buys a generic welder title. Vessel diameter, seam class, leak test and the wire-feed synergic program list change the packet even when two photos look alike.

01

EV battery tabs

Copper and aluminum stacks when the same plant also builds cooling tanks; pulse energy and spatter limits stay written.

02

Medical housings

Stainless seams, Ra callouts, ISO 13485 trail if the shop shares a medical line with tank work.

03

HVAC exchangers

Thin aluminum coils next to tank shells; distortion and leak-test coupons stay named.

04

Enclosure fab

Mild steel and stainless corners when a tank family also needs panel boxes.

05

Robot cells

Circumferential tank seams, fixture plates, cycle-time assumptions versus a booth.

06

Aerospace brackets

AS9100 evidence, FAI sections, ITAR if a tank drawing is marked.

07

Electronics frames

Thin-wall heat input when a tank integrator also sources small frames.

08

Implement frames

Thicker carbon steel, filler wire, outdoor coating after weld on reservoir frames.

Laser Welding Machine Manufacturers Sourcing is an independent sourcing partner for tank-cell RFQs. Factory wholesale quotations sit next to freight, duty, booth or robot install, and the written synergic program set so buyers can see landed procurement cost on one tank family.
