Galvanized pipe welding processes can be divided into spiral welded and straight seam welded, and galvanized spiral welding process is relatively wider number of applications, but also more complex.

Galvanized spiral pipe welding method is first out of the forward end portion of the electrode about 5 ~ 7mm, without leaving a blunt edge technology for centralized control to ease the industry needs to pay attention to seriously handle groove dimensions and near-plated zinc layer.

For penetration, undercut the tendency will be very small, If the front and rear of the round-trip transportation technology is used, generally 1.5 ~ 2.5mm; to reduce zinc weld penetration, with a focus on playing groove industry downturn, such as the use of short welding slag such as J427, to leave some space sector is expected to greatly reduce the liquid zinc remain in the weld, when welding fillet welds, you can get no defects of welding quality.

Advantages of galvanized spriral welding: the welding precision can not be compared for the straight seam welding, large diameter pipes or some special pipes are all used the spiral welded pipe, because spiral welding welding density is big, welding up is very flexible, welded together can form a variety of changes.

But straight seam welding can only weld one line, the curve of straight seam welding completely couldn't play the advantages, therefore, The use of spiral welded is the best choice.
