What is the best way to super-wave stainless steel plate welding? With the continuous expansion of China's stainless steel market, stainless steel consumption has increased year by year, thin-walled stainless steel has also been deep into a variety of manufacturing areas, so thin-walled stainless steel plate welding production process will become an important process , By the thin-walled stainless steel welding process itself determines the characteristics of the difficulty of its welding.       Thin stainless steel welding machine is the most intractable problem is the welding wear, deformation: stainless steel sheet binding degree is small, in the welding process by local heating, cooling, the formation of uneven heating, cooling, weldment will produce uneven stress and Strain, the longitudinal shortening of the weld on the edge of the sheet pressure exceeds a certain value, that will produce more severe wave-shaped deformation, affecting the quality of the workpiece shape.       The main measures to solve the burning and deformation of stainless steel sheet are:       (1) strictly control the heat input on the welded joint, select the appropriate welding methods and process parameters (mainly welding current, arc voltage, welding speed);Stainless steel wire suppliers       (2) to the precise size of the assembly, the interface gap as small as possible. The gap slightly larger easy to burn through, or the formation of large welding tumor;430F cold drawn stainless steel round bar       (3) must be hardcover fixture, clamping force balance. Welding of stainless steel sheet key to note: strictly control the welding joint line energy, to be able to complete the welding under the premise of minimizing heat input, thereby reducing the heat affected zone, to avoid the emergence of the above defects.304 Stainless Steel Bar Equipment       TIG welding deformation of stainless steel sheet can not be avoided, only the use of sub-step backward welding method, the use of current should not be too large, to minimize the heating time of the plate, so that deformation of the board to minimize.304 Stainless Steel Pipe Solid In Structure       Stainless steel sheet is the best laser welding 0.1MM can be welded, laser spot size of arbitrary regulation, can be a very good control. Deformation than this is not.
