Distortion, Residual Stress, And FixturingLaser welding’s concentrated heat input significantly reduces distortion compared to MIG or TIG welding, but stainless steel’s thermal expansion rate (~17 µm/m·℃) is still almost 1.5×that of carbon steel.···

Heat Input, Cooling Rate, And Metallurgical ControlLaser welding is inherently a low heat input, high cooling rate process, which is one reason it’s so effective for stainless steel. But “low heat” is not automatically “good” — the wrong heat inp···

Shielding Gas StrategyIn stainless steel laser welding, shielding gas is not just about keeping oxygen away from the molten pool—it directly influences weld penetration, bead shape, spatter levels, and final corrosion resistance. The concentrated···

Equipment and SetupLaser welding stainless steel requires carefully matched equipment to ensure stable performance, high-quality welds, and consistent production. The right combination of laser source, beam delivery system, motion control, and sh···

Laser Welding FundamentalsUnderstanding the fundamentals of laser welding is essential to produce strong, consistent welds in stainless steel. The process relies on tightly controlled parameters that determine penetration depth, weld width, and h···

Why Laser-Weld Stainless Steel?Laser welding offers several advantages that make it one of the most effective methods for joining stainless steel. Its unique combination of speed, precision, and minimal thermal impact delivers results that are di···

Laser welding gun maintenanceThe laser welding gun is a component that directly performs welding work. The quality of welding has a great relationship with the use of the welding gun components. Therefore, before each use of the machine, the lase···

Operating environment requirementsWhen using a laser welding machine, it is necessary to create a good operating environment for the machine. This is the prerequisite for the long-term stable use of the machine. The following are the requirements···
