Galvanized pipe welding connection method:
1. Galvanized Steel Pipe mouth is not in a straight line after docking and Steel Pipe has the problem of diagonal. It is recommended to cut off a small section of steel pipe head before processing.

2. After the joint of Galvanized Steel pipe orifice, the joint of two pipe orifice is not strict, resulting in uneven welding thickness; As well as the steel pipe due to its own reasons or transportation bump, resulting in the pipe mouth oval, it is recommended to cut off a small section of the pipe head before processing.

3. Sand holes appear at the pipe orifice of galvanized steel pipe after docking:
