Stainless steel is the most widely used and cost-effective steel surface treatment method in today's society. The term “stainless steel” refers not only to a type of stainless steel, but to more than one hundred industrial stainless steels, each of which has been developed for its specific application. The key to success is first to clarify the purpose and then determine the correct steel grade.
At present, the most dealing with us in the market is 304 stainless steel. 304 stainless steel may be just a lot of listeners to many people, but actually don't know what it means. 304 is actually a general-purpose model; that is, 18/8 stainless steel. Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard ingredient is 18% chromium plus 8% nickel. It is a non-magnetic stainless steel that cannot change its metallurgical structure by heat treatment.
Some stainless steel products manufacturers now use argon arc welding and other common welding machines. Although these can meet the production needs, they will leave welding defects such as undercut, incomplete penetration and dense pores during the welding process. And cracks not only reduce the firmness of the joint, but also become a source of corrosion for crevice corrosion. In the welding process, not only the welder's technology has a certain level, but also the welding skill and the cost of the flux are too large, which will increase the cost of production. Moreover, the working steps of processing after welding bring unnecessary troubles. Technology is constantly improving, and because of these defects, a new type of stainless steel continuous laser welding machine is born!
Stainless steel continuous laser welding machine----small power pulse laser seam welding has the advantages of high power density, energy concentration, small heat input, narrow weld seam and small deformation, and the laser beam can be focused to obtain a small spot. Positioning, these features make laser seam welding more suitable for welding small workpieces than other welding methods. For laser welding of ultra-thin stainless steel materials, due to the thin material, it is easy to vaporize the perforations, in order to obtain a continuous, non-burn through weld. The key is precise control of the parameters.
Riselaser specializes in producing a series of laser equipment such as fiber laser welding machine, continuous laser welding machine, YAG laser welding machine and stainless steel laser welding machine.
