Laser Welding Service in Chicago & DuPage County

Laser Welding Materials and Applications

Laser welding is the right call when conventional welding heat would warp, crack, or damage the part. The focused beam concentrates heat into a spot smaller than the head of a pin — meaning the rest of the part stays cool, dimensionally stable, and dimensionally unchanged.

Materials we laser-weld:

• Tool steels — H13, D2, A2, S7 — mold and die repair, tooling restoration
• Stainless steels — medical, surgical, food-grade, aerospace
• Aluminum and aluminum alloys — precision parts, electronics housings, architectural finish
• Titanium — medical implants, aerospace, jewelry
• Precious metals — gold, silver, platinum (jewelry, antique restoration)
• Inconel and superalloys — high-temperature aerospace and industrial
• Copper, brass, bronze — fine jewelry, decorative restoration, electronic contacts

Common laser welding applications:

• Mold and die repair — restore worn or cracked tooling without warpage
• Tooling restoration — punch and die, plastic-injection molds, stamping tools
• Jewelry repair and fabrication — ring sizing, prong repair, stone-set work
• Medical and surgical instrument repair
• Antique watch and clock restoration
• Electronics enclosures and connectors
• Specialty automotive and racing parts
• Hairline cracks in stainless and tool steel

All laser welds performed to AWS standards with material-specific filler wire and inert gas shielding.

Laser Welding Customers We Serve

Laser welding requests come from customers who’ve already decided that precision and zero heat distortion matter more than welding speed or cost. The job is always the same idea: fix the part without warping it, cracking the surrounding surface, or destroying the finish.

• Mold makers and tool & die shops — plastic-injection mold repair, stamping die restoration, tool steel rebuilding
• Manufacturers and production shops — broken production tooling that can’t be replaced fast
• Medical device shops — surgical instrument repair, sterilization-grade weld work
• Jewelers and goldsmiths — ring repair, prong rebuild, antique jewelry restoration
• Watchmakers and clock restorers — antique mechanism repair, broken pivot rebuilding
• Aerospace component shops — exotic alloy repair, tight-tolerance precision welds
• Specialty automotive and racing — high-end parts, exotic alloy work
• Antique restorers — small heat-affected zone keeps original patina and finish intact

If the part is too small, too valuable, or too heat-sensitive for conventional welding — laser is usually the answer.

Laser Welding Standards and Safety

Laser welding is one of the safest welding processes from a contamination and fume standpoint, but the laser itself is a Class IV laser hazard that requires controlled access and proper enclosures. Every laser job follows:

• AWS C7.4 / D17.1 — laser welding process standards and aerospace welding code (when applicable)
• OSHA welding & cutting standards — adapted for laser process
• ANSI Z136.1 — safe use of lasers (Class IV laser controls)
• ANSI Z49.1 — safety in welding, cutting, and allied processes

What that means on every laser welding job:

• Class IV laser enclosure with interlocked access — no welding without enclosure closed
• Approved laser-safety eyewear rated for the specific wavelength
• Material-specific filler wire and inert gas shielding (argon, helium, or argon blends)
• Pre-weld surface prep — cleanliness matters even more than with TIG
• Joint geometry tested for fit before laser is fired
• Quality control inspection — laser welds are easy to inspect for porosity and lack-of-fusion
• Workmanship guarantee in writing

Why Chicago Mold Makers, Jewelers, and Specialty Manufacturers Pick American Welding for Laser

Laser welding is a specialty within a specialty. Most welding shops don’t offer it because the equipment investment is significant and the work is precision-driven. Here’s what you get with American Welding:

• 37 years of welding experience applied to laser work — same hand quality, smaller heat zone
• Mold and die repair specialty — restore worn tool steel, fix hairline cracks, rebuild stamping dies without warpage
• Jewelry-grade precision — ring repair, prong rebuilding, antique restoration with no surrounding heat damage
• Medical and surgical instruments — sterilization-grade welds, no contamination, full inspection
• Antique restoration without finish damage — original patina and surrounding finish stay intact
• Honest assessment — if a job is better suited to TIG or another process, we say so
• In-shop precision work — laser welding is a controlled-environment process; our shop has the proper enclosures and fixtures
• Workmanship guaranteed in writing

If conventional welding heat would ruin the part, laser is the answer. Precision over speed, every time.
