The application of laser welding of 304 stainless steel

by:J&D WATER     2020-03-21
In laser welding industry, the use of the manufacturer of laser welding of stainless steel workpiece is very much, laser welding machine the welding effect is also very good, 304 stainless steel material nature by laser welding is also a good choice. Laser welding machine for welding compared with the traditional welding, low power pulse laser seam welding with high power density, energy concentration, low heat input and welding seam narrow and the advantages of small deformation, and the focused laser beam can be obtained after a small spot, precision positioning, these characteristics make laser seam welding is better than other welding method is suitable for the welding of small size workpieces. For laser welding ultra-thin stainless steel materials, because the material is very thin, easy vaporization perforation, to get a continuous, no burning through the weld. The key is the precise control of the parameter. Main parameters affect the quality of laser welding such as welding current, pulse width, pulse frequency, its effect is mainly as follows: ( 1) With the increase of current, the increase of the width of the weld, the welding process developed splash, weld surface oxidation phenomenon, and has a rough feel. ( 2) Along with the increase of pulse width, the width of the weld is also increased. The change of the pulse width of stainless steel ultra thin the effect of the laser welding machine for welding effect is very significant. The small increase of the pulse width could lead to a sample was oxidized and burn through. ( 3) With the increase of the pulse frequency, the solder joint overlap rate increase, the weld width increase first. After the basic remain unchanged. Under a microscope, the weld is more and more smooth and beautiful. But the pulse frequency increases to a certain value, serious splash welding process, weld become coarse, and weldments oxidation occurs on both sides. ( 4) Ultra thin sheet materials of laser welding is suitable for use are from coke, coke in the same amount of cases, are from the confocal laser welding the weld surface is smooth and beautiful than negative out of the coke.
