The welding flange using scale and Forging Technology

　　The use of welding scale? Butt welding of high productivity, easy to automate, so has been widely used. The scale of its use can be summarized as follows:

　　Ground long such as strip, profiles, wire rod, steel, rail, steel boiler, oil and natural gas delivery pipe butt welding of the workpiece (1).

　　(2) butt welding annular workpieces such as automobile and bicycle and motorcycle rim rim butt welding, butt welding of various links.

　　(3) components of the welding will be rolling, casting, stamping or simple machining parts welded into a messy parts, in order to reduce the cost. Such as shell of automobile steering shaft and axle housing of butt welding, butt welding of various connecting rod, a pull rod, and special parts of the butt.

　　(4) butt welding of dissimilar metals can save precious metals, improve product function. Such as tool operation some (HSS) and tail (steel) butt welding, internal combustion engine exhaust valve head (heat-resisting steel) and tail (steel structure) butt welding, copper conductive joint butt.
