Basic Knowledge of Sheet Metal Processing - Welding Processing (4)

We will introduce the basic knowledge of sheet metal processing.

"Welding processing" refers to the process of joining two or more metal parts together. This page introduces "YAG laser welding," which is one of the welding methods implemented at Tubota Technica. ○ Laser Beam Welding Laser beams are directed onto the base material, and the energy from the laser is used to weld the material. Depending on the method of generating (oscillating) the laser light, it can be divided into several types. ・YAG Laser Welding This method uses a laser generated from a yttrium-aluminum-garnet (the initials YAG) alloy of yttrium and aluminum to perform the welding. It can weld stainless steel, which is prone to distortion from heat, with minimal impact, and it allows for deep penetration, resulting in a strong joint. No filler material is used; instead, the melted base materials are joined directly (this is called butt welding). There is no variation in the thickness of the weld seam. It is often used for welding stainless steel and electroplated steel sheets. In "Basic Knowledge of Sheet Metal Processing - Welding Processing (5)," the characteristics of fiber laser welding will be introduced.
