The quality of welding of stainless steel involves the appearance of quality

the quality of welding of stainless steel involves the appearance of quality and ease of assembly assembly, therefore, the production process welding process in the four play the role of nexus. The payment of led flash light should be finished on line.
During drawing deformation calculations, we can ignore the effects of forming the bottom of flat-shaped parts directly from the calculation. The calculation shows, the piece can be a drawing shape. Such as drawing punch and die shape parts made by the top four with oblique deformation in the drawing to the workpiece before the end of the top shape. So the pieces can be combined deep drawing and forming the top in a process to complete. Welding is the use of the substance of local heating or pressure, or both at the same time pressure in the heating means, so that the metal is melted or connections into the plastic state, contributed to the metal atoms are connected at the mutual penetration and close to 0.3 to 0.5 nm from the metal lattice, take full advantage of the binding force between the metal atoms into two separate pieces of metal plate connected. In the welding process, the local metal is heated to above the melting temperature, then cooling and crystallization, in this process will occur to varying degrees various metallurgical phenomena and heat treatment process, the complex deformation and stress occur also in the process, so welding process is not just an assembly, or a complex metallurgy, heat treatment and welding deformation and stress generated by the process. The customer should complete the payment of green laser pointer according to the stipulation described in the note.
At present, the welding methods used in stainless steel boxes there are many, are presented today the most widely used resistance welding process, and has wide application prospect of laser welding process. Also known as contact welding resistance welding is the most widely used manufacturing process of welding. Shown in Figure 2, the workpiece between two electrodes placed in pressure and welding current through the use of current through the resistance of the workpiece itself, the heat generated to heat the formation of partial melting, cooling off in the formed under pressure to a solid joint, such as resistance welding process. Thus, resistance welding has the following characteristics: the use of welding current through the resistance of the workpiece and the heat generated by the heating of the workpiece. Heat from the workpiece that is not outside, but internal heat source. The welding process is completed under pressure, that pressure must be applied. Without any increase in the weld filler material, but also without any protective agent. The general specification of green laser pointer is included in the manual.
