Laser-welded EV busbar coupons on an inspection tray

APPLICATION INDEX

Laser welding machines manufacturer uses, translated into purchase requirements

Name the tank program, documents, delivery stages and site constraints. A robot cell for repeating circumferential seams is not the same RFQ as a manual booth for mixed vessel diameters, even when both weld stainless.

Application cards

EV

Battery tabs and busbars

Copper/aluminum stacks when a tank integrator also welds cooling reservoirs. Pulse energy, spatter and porosity limits stay written.

MED

Medical device housings

Stainless seams, Ra, ISO 13485 files, lot traceability if the same shop shares medical work with tanks. Ask for FAI photos on the cosmetic face.

HVAC

Heat exchangers

Thin aluminum next to tank shells. Distortion and leak-test coupons decide gantry versus robot.

FAB

Sheet metal enclosures

Mild steel and stainless corners around a tank skid. A booth may suffice until cycle time or seam tracking appears.

AUTO

Body and bracket cells

IATF 16949 and PPAP questions belong on the RFQ if a reservoir cell feeds a launch, not as our certificate.

AERO

Aerospace brackets

AS9100 evidence, NADCAP if heat treat follows, ITAR if a tank drawing is marked.

ELEC

Electronics frames

Thin-wall heat input, grounding tabs, cosmetic faces when a tank shop also sources small frames.

AG

Implement frames

Thicker carbon steel, filler wire, coating after weld on reservoir frames. Site power and extraction often dominate cost.

Questions grouped by purchase stage

Use

State coupon work, a mixed-diameter booth, or a repeating robot cell on one tank family. EAU and shift pattern change payload, fixture plates and spare-kit lines.

Mild steel, stainless, aluminum and clad tank walls do not share one process window. List thicknesses and any coated stock before asking for a synergic program list.

Documents

CoC, mill certs on sample plate, FAI photos, CMM on fixtures, CE/UL panel file, laser class, and the wire-feed synergic program list. Name the report format.

If the drawing or destination is export-controlled, write that before we circulate a pack. We do not assume clearance.

Site

Door size, pit, three-phase power, extraction duct, gas storage and floor loading for a tank robot cell or booth. These often exceed the resonator line.

Offshore unit cost can look lower; domestic routes can shorten DFM loops and on-site audits of a tank cell. Place factory wholesale quotations beside freight and duty, not beside a slogan.

Packets to request, not files we host

This compact list is a reminder of supplier documents. Links open the inquiry form because this site does not host factory PDFs we have not received.

  • PDF

    Sample-cut / sample-weld method

    Ask the laser welding machines manufacturer to state coupon size, section photos and who pays NRE on the tank family.

    Request
  • XLS

    Utility checklist

    Power, gas, chiller tons, extraction, and whether the wire-feed synergic program list is included. Keep it as a line item, not a verbal aside.

    Request
  • DOC

    Acceptance and commissioning boundary

    Days on site for a robot cell or booth, training seats, spare kit, what “run-off” includes.

Turn the application into a factory RFQ

Share tank-family use, quantity, destination and the document pack you need. We will collect factory wholesale quotations for that locked tank brief, including robot-or-booth and synergic-program lines.
