As far as the current laser technology is concerned, the development of laser technology is more and more mature. Of course, one of the more widely used laser technology is laser welding technology. Although the technology is improving constantly, there are still some defects, such as deformation sometimes occurs when laser welding is done by laser welding machine. 2000w hand-held fiber laser welding machine manufacturers tell you how to avoid laser welding deformation.

At present, stainless steel is widely used in laser welding materials. Because of its corrosion resistance and formability, stainless steel has been widely used in aerospace, auto parts and other industries. Laser welding plays a key role in the application of stainless steel, especially in automobile manufacturing. But the butt welding of stainless steel plate is difficult to deform and operate.

The key factors affecting welding deformation are welding alternating current, pulse width and remote frequency. 2000w hand-held fiber laser welding machine with the increase of alternating current welding, the total width of welding will also increase, slowly appear sputtering and other conditions, will cause oxidation deformation of welding surface, accompanied by rough; With the increase of the total width of the pulse width, the stiffness of the butt joint can be increased. When the total width of the pulse width is higher than the energy level, the heat transfer energy metabolism of the material surface will also be changed. Volatilization will make the liquid splash out from the molten pool, resulting in the reduction of the cross section of spot welding, affecting the hardness of the joint.

The harm of welding deformation of stainless steel plate is closely related to the thickness of stainless steel and other factors. For example, 0.5mm stainless steel plate, when the frequency of 2000w handheld fiber laser welding machine reaches 2 Hz, the weld conformity rate is higher. However, when the frequency reaches 5 Hz, the welding seam burns seriously and the heat affected zone is wide, resulting in deformation. Therefore, it is very important to strengthen the reasonable control of welding deformation.
