Laser welding joins metal with a focused, high-energy laser beam instead of an electric arc — fast, precise, and low-distortion. This guide explains the process, compares it to traditional welding, and shows how a machine is used.
What Is Laser Welding?
A concentrated laser beam melts a narrow line of metal that cools into a strong weld. Because heat is focused, there’s little warping and usually little grinding. It works on stainless steel, carbon steel, galvanized sheet, aluminum and brass.
Key Specifications & Performance (the basics)
Power sets weldable thickness and speed; cooling (air vs water) sets duty cycle; gun weight affects fatigue; wire feeding handles gap filling; pulse mode suits thin/precision work.

For most export buyers, the real question isn’t power alone — it’s matching the machine to your material and duty cycle. A well-configured handheld system handles the vast majority of fabrication jobs without over-spec’ing.
