Laser Welding Service Chicago & DuPage | American Welding

Since 1980, American Welding has welded almost everything that can be welded across Chicago and the suburbs.

Adding laser welding to the shop has opened the door to precision repairs and joins that traditional welding can't deliver, all backed by a workmanship guarantee.

What Is Laser Welding?

Laser welding uses a tightly focused beam of light to heat and fuse metal, rather than an electric arc, as in MIG, TIG, or Stick welding. The beam is so small and precise that it can melt the joint without heating the surrounding metal.

That precision is the whole point. Where traditional welding heats a wide area, laser welding works in a tiny zone, joining the metal cleanly without warping, discoloring, or stressing the surrounding piece.

How Laser Welding Works

The basic idea is simple: focused light hitting a single spot generates enough heat to melt metal in a fraction of a second. The laser is precisely aimed at the weld location, fires for a controlled duration, and creates a small, controlled weld point. Move the beam (or the part) along the joint, and you get a clean welded seam.

Three things make laser welding different from a torch:

• The heat is concentrated: only the spot under the beam melts; the metal around it stays cool
• The weld is fast: most laser welds happen in fractions of a second
• The control is exact: power, timing, and beam size can all be dialed in for the specific job

That control is what makes laser welding useful for jobs that traditional welding can't safely handle.

Advantages of Laser Welding

Laser welding doesn't replace traditional welding; it adds capability for jobs that need precision, speed, and minimal heat damage.

For jobs where heat or finish matters, laser welding is the right tool.

What Laser Welding Can Join

Laser welding works on most common metals, and a few that traditional welding handles poorly:

• Stainless steel: surgical tools, kitchen equipment, decorative pieces
• Aluminum: thin panels, marine fittings, custom parts
• Carbon steel: precision components, mold repair
• Titanium: high-performance and specialty parts
• Copper and brass: fine repairs, decorative work, jewelry-style joins
• Gold and silver: jewelry repair, fine decorative work
• Different metals together: laser welding can join some metal combinations that traditional welding can't handle

The right approach depends on the metal, the thickness, and the joint.

Some metals weld better than others, and we'll tell you straight if laser welding is the right call for your job.

Common Jobs and Industries

Laser welding handles the kinds of jobs traditional welding either can't do or would damage:

• Mold and tool repair, such as small cracks, worn corners, and broken sections
• Stainless steel kitchen equipment: precision repairs on prep tables, sinks, and decorative pieces
• Surgical and medical tools: fine repairs on thin stainless instruments
• Jewelry repair: precious metal joins without melting the surrounding piece
• Automotive precision: thin body panels, mounting brackets, custom parts
• Aerospace: lightweight, high-precision components
• Sheet metal work: very thin stainless steel and aluminum
• Decorative metalwork: near-invisible joints on architectural pieces

The industries that use laser welding most are manufacturing, medical, automotive, aerospace, jewelry, and high-end custom fabrication.

Laser Welding Aluminum

Aluminum is one of the toughest metals to weld with a torch. It pulls heat away fast, warps under traditional welding heat, and shows every flaw. Laser welding handles aluminum cleanly:

• The concentrated heat melts the joint without warping the surrounding panel
• Thin aluminum sheets can be welded without burning through
• The weld is fast enough that the rest of the piece never reaches damaging temperatures
• Joints come out clean, with minimal cleanup needed

For thin aluminum panels, fine aluminum parts, or precision aluminum repairs, laser welding is often the only realistic option.

Where Laser Welding Falls Short

Laser welding isn't the answer for every job. The places it falls short:

• Thick structural steel: beams, heavy plate, and structural work need the heat and penetration of a torch
• Long, heavy welds: laser welding is built for precision, not running long beads on thick metal
• On-site outdoor jobs: the laser welder lives in the shop; field repairs go to the truck
• Dirty or rusted metal: laser welding needs clean surfaces; heavily corroded or contaminated metal usually needs traditional methods after cleanup
• Some reflective metals at certain thicknesses: copper, for example, takes a specialized setup
• When cost outweighs benefit: for simple repairs that don't need precision, traditional welding is often the better call

We'll tell you up front when laser welding isn't the right tool for the job, and recommend the method that is.

When Laser Welding Is the Right Call

Laser welding belongs on jobs where:

• The metal is too thin for a torch
• The surrounding area can't tolerate the heat
• The weld has to be invisible or near-invisible
• The repair is fine, precise, or in a tight spot
• A traditional weld has already been tried and failed
• The metal is a specialty alloy that traditional welding handles poorly

When any of those describe the job, laser welding is the right answer.

From Crack to Closed — A Laser Welding Visit

Every laser welding job moves through the same steps:

1. Call or text (630) 927-3030 — describe the part, send photos if possible
2. Free consultation — confirm laser welding is the right method for the job
3. Drop off or shipping — most laser welding parts come to the shop, since the laser welder lives there
4. Inspection and quote — clear pricing before any work starts
5. Surface prep — metal cleaned and positioned for precise welding
6. The weld — laser fires precisely on the joint, in controlled passes
7. Finish and inspection — joint checked, cleaned up if needed, and shown to you
8. Workmanship guarantee on every weld

Most laser welding jobs are wrapped up in a single shop visit. Larger or custom work may take longer depending on the project.

Frequently Asked Questions

What is laser welding?

Laser welding uses a tightly focused beam of light to melt and fuse metal instead of an electric arc. The heat is concentrated in a tiny spot, so it joins the metal without warping or damaging the surrounding piece.

What metals can be laser-welded?

Stainless steel, aluminum, carbon steel, titanium, copper, brass, and many precious metals. Some combinations of different metals can also be joined by laser welding, which traditional welding can't handle.

Is laser welding stronger than traditional welding?

For thin metal and fine joints, yes. The bond is clean and strong with minimal damage to the surrounding metal. For thick structural welds, traditional methods like MIG or Stick are usually stronger because they put more heat into the joint.

Can laser welding be done on aluminum?

Yes, laser welding works very well on aluminum, especially thin aluminum that would warp or burn through with traditional welding. The fast, focused heat lets the joint melt without distorting the surrounding metal.

Can laser welding repair a cracked mold or tool?

Yes, mold and tool repair is one of the most common uses for laser welding. Small cracks, worn corners, and broken sections can be filled and rebuilt without damaging the rest of the piece.

Is laser welding done on-site or in the shop?

Laser welding is done in the shop. The equipment is fixed in a controlled environment for safety and precision. Field welding is done with traditional methods on the service truck.

How much does laser welding cost?

Laser welding usually costs more per inch than traditional welding because the equipment and skill required are specialized. For the right job, it saves money overall by reducing rework, replacement, and damage to surrounding metal. Every quote is clear and upfront before work starts.

What are the advantages of laser welding?

Minimal warping, clean welds with little or no cleanup, fast work on fine joints, the ability to weld in tight spots, and the option to join metals that traditional welding can't handle well.
