The welding of copper and stainless steel is often encountered, and the welding is difficult. The main performance is that it is very sensitive to the penetration crack of copper during welding. ; The second is to choose the appropriate filling material, control the elements that are prone to low-me

Flux is a granular welding material. It melts to form slag and gas during welding, and plays a protective and metallurgical role for the molten pool. When welding, it melts to form slag and gas, and acts as a protective and metallurgical treatment for the molten metal.CompositionFlux is composed of

Water jet cutting uses nozzles to produce a high pressure water jet carrying fine abrasive particles for cutting. This method is very effective in cutting both metallic and non-metallic materials. The process uses high capacity pumps with very high water and electricity requirements. This method can

Many methods of joining stainless steels are able to be applied well to ferritic stainless steels, mainly including.(1) Melt welding By melting the base material and the filler metal after recrystallization so that the two or more materials separated from each other to achieve a complete bond.(2) So

Heat exchanger, as the heat transfer equipment that transfers part of the heat from the hot fluid to the cold fluid between materials, has a wide range of applications in people's daily life and in petroleum, chemical, power, pharmaceutical, atomic energy and nuclear industries. It can be used as in

Welding is a process in which the material of the workpiece to be welded (same or different) is heated or pressurized or both are used,and whether or not to use a filler material, so that the material of the workpiece can achieve atomic bonding and form a permanentconnection process. So what are the

Causes of porosity1. Base metal is dirty, the groove edge is not cleaned2. The composition and properties of the welding materials used are quite different from those of the base metal3. Welding shielding gas problema) Insufficient argon pressure in the cylinder;b) Excessive adjustment of welding ga

(1) The main research object of welding labor hygiene is fusion welding, among which open arc welding has the greatest labor hygiene problems, and submerged arc welding and electroslag welding have the least problems. (2) The main harmful factors of shielded electrode manual arc welding, carbon arc
