The general problem of half-pipe jacket is the leakage of the welding line induced by crack.
The invention is used for automatic air gouging back gouging of the straight welding line and the girth welding line of the large cylindrical welding structure.
The failure form of Ji 'nan luminous character after being subjected to electric shock is not fixed, but it usually causes welding line damage.
Surface treatment: Apply the surface treatment techniques like polishing, acid treatment and passivation to treat the welding line, hole, screw to ensure that the surface meets the GMP standards.
The machine can not only process the U、 V welding line of end sloping back ridging, edge cutting for carbon steel stainless steel and allayed steel pipes, but also can treat the welded convex flange and plain flange.
