Stainless steel
Stainless steel is the most widely used steel surface treatment method in the world. The word “stainless steel” is not just about a single kind of stainless steel, but more than one hundred kinds of industrial stainless steel. Each kind of stainless steel developed has good performance in its specific application field. The key to success is first to clarify the purpose and then to determine the right type of steel.
304 steel
Now, the 304 largest steel company we deal with is steel. 304 for many people, they may just listen much, but actually they don’t know what it means. 304 is in fact a general model, that is, 18/8 stainless steel. Products such as corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard component is 18% chromium and 8% nickel. The stainless steel is non-magnetic and can not be changed by heat treatment to change its metallographic structure.
Some stainless steel manufacturers are now commonly used in argon arc welding and other ordinary welding machines. Although these can meet the needs of production, they will leave welding defects in the process of welding, such as bite, non penetration, dense pores and cracks, not only to reduce the firmness of the joint, but also to corrosion corrosion. Source. In the welding process, not only the welder’s technology has a certain level, but also the welding skills and the cost of flux are too large, which will improve the cost of production. Moreover, the working procedure after welding will bring unnecessary trouble. Technology is progressing. It is because of these defects that the new type of stainless steel continuous laser welding machine is born.
The continuous laser welding machine of stainless steel – small power pulse laser seam welding has the advantages of high power density, energy concentration, small heat input, narrow weld and small deformation, and the laser beam can get very small spot and precision positioning. These features make the laser seam welding more suitable for small size workpiece than his welding method. Welding. For ultra thin stainless steel laser welding, because of the thin material, it is easy to vaporize the perforation, so as to get a continuous, non burn weld. The key is the precise control of the parameters.
