Stainless steel is often classified according to the state of the organization: martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardened stainless steel. In addition, it can be divided into: chromium stainless steel, chrome nickel stainless steel and chromium manganese nitrogen stainless steel. There is also special stainless steel for pressure vessels. GB24511_2009_Stainless steel plates and strips for pressure equipment

Laser deep-fusion welding generally uses a continuous laser beam to complete the material connection. The metallurgical physical process is very similar to electron beam welding, that is, the energy conversion mechanism is completed by a "key-hole" structure. Under high enough power density laser illumination, the material evaporates and forms small holes. The beam continuously enters the small hole, and the material outside the small hole flows continuously. As the beam moves, the small hole is always in a flowing stable state. That is, the small holes and the molten metal surrounding the walls of the holes move forward with the advancement speed of the leading beam, and the molten metal fills the gap left after the small holes are removed and condenses, and the weld is formed. All of the above processes happen so quickly that the welding speed can easily reach several meters per minute.
