Automatic Enclosed Precision Laser Welding Machine 2000W for Metal Parts

Both grades weld with similar parameters, but 316L requires slightly higher power for equivalent penetration due to its higher thermal resistance. The machine stores separate weld programs for each material grade, allowing operators to switch between 304 and 316L parts by selecting the corresponding program.

Discoloration on stainless steel indicates oxidation, which occurs when the heated metal is exposed to oxygen before it cools below the reactive temperature. The enclosed cabinet maintains consistent argon shielding coverage from pre-flow through post-flow. The post-flow continues until the weld zone cools sufficiently, producing bright, clean welds without the blue or straw-colored discoloration that indicates oxidation.

Using the 1500W configuration with fine-focus optics and optimized pulse settings, stainless steel as thin as 0.1mm can be welded. The combination of reduced spot size, precise pulse shaping, and stable argon coverage is essential for weld quality at these thicknesses.

Yes. The machine produces smooth, crevice-free weld beads on both 304 and 316L stainless steel. The enclosed cabinet minimizes surface contamination, and the controlled argon coverage helps maintain the corrosion resistance of the weld zone-both of which support the production of parts intended for cleaning and sterilization processes.

With proper argon shielding and optimized pulse parameters, stainless steel welds come out bright and clean with minimal discoloration. The heat-affected zone is narrow and uniform. For cosmetic-grade visible surfaces on medical equipment, food processing machinery, or laboratory instruments, the weld typically requires no post-weld polishing or only minimal finishing.
