cooling and crystallization of various metallurgical phenomena

Through process optimization, to find a more suitable process parameters, the use of this technology for precision cutting on stainless steel plate can improve our competitiveness in the steel industry. Laser cutting welding production line, equipment selection and layout design in stainless steel boxes, stamping, welding, painting, assembly technology, welding quality involves the appearance of stainless steel quality and the ease of assembly assembly, therefore, welding The installed production process from the connecting role in the four process. (A) of the workpiece structure during drawing deformation calculations, we can ignore the bottom of the forming directly calculate the flat-shaped parts. The calculated results can be a drawing shape. And at this moment, the energy of concentrated in the small dot will be greater so that the match might be lit by laser pointer when the condition is appropriate enough.
Such as at the top of the drawing punch and the die made of parts shape surrounded with oblique deformation, forming before the end of the drawing to the workpiece at the top. Can pull the pieces deep and the top of the molding compound in a process to complete. Welding process analysis in real terms of welding a stainless steel box plan (b) the use of local heat or pressure or both heated and pressurized way to be connected at the molten metal or plastic state, contributed to the junction the metal atoms penetrate each other and close to the distance of 0.3 ~ 0.5nm metal lattice, and take full advantage of the binding force between the metal atoms of two separate metal plates connect. For example, if the power of laser pointer is 50mW and at this time the laser pointer can not light the match or black material.
In the welding process, the local metal is heated to above the melting temperature, cooling and crystallization of various metallurgical phenomena and heat treatment process will occur in this process, the complex deformation and stress also appears in these processes, so welding is not just an assembly process is a complex process metallurgy, heat treatment and welding deformation and stress. At present, the welding method applied to the stainless steel box there are many, are presented the most widely used resistance welding process, and has wide application prospects of laser welding process. A resistance welding resistance welding, also known as contact welding is the most widely used welding methods in the manufacturing process.
