What about laser welding deformation? How to avoid it?

From the early development of laser welding machines to the present, the technology has gradually matured, and various types of welding machines have been derived. Despite technological advancements, there are still deficiencies. laser welding service ，For example, laser welding machines sometimes deform during laser welding, so how to avoid laser welding deformation.


The key factors affecting butt welding deformation are welding AC current, pulse width and frequency. When the welding AC current increases, the total welding width also increases, and sputtering occurs gradually, resulting in oxidation deformation of the welding surface, accompanied by roughness; the increase of the total pulse width can increase the hardness of the welded butt joint.


When the total pulse width is higher than the necessary level, the heat transfer energy metabolism on the surface of the material will also increase, and the volatilization will cause the night body to splash out of the molten pool, resulting in a reduced cross-section spot welding, which will affect the hardness of the terminal.


The harm of butt welding frequency to the welding deformation of stainless steel plate is closely related to the thickness of stainless steel and other factors. In the final analysis, it is imperative to strengthen the reasonable control of butt welding deformation.
