Weld leveling of straight seam steel pipe
by admin on 22-12-28
Weld leveling of straight seam steel pipe (lsaw/erw): Due to the impact of the welding current and the influence of gravity, the internal weld of the pipe will protrude, and the external weld will also sag. If these problems are used in an ordinary low-pressure fluid environment, they will not be...

Short joint welding of oil casing
by admin on 22-12-22
The oil casing is short joint, causing this phenomenon due to internal mechanical failures such as roller or shaft eccentricity, or excessive welding power, or other reasons. As the welding speed increases, the tube blank extrusion speed increases. This facilitates the extrusion of the liquid met...
