Fixed welding means that the joints of the steel pipes cannot be moved after being assembled, and the welding is performed according to the change of the welding position (horizontal, vertical, upward, and mid-level changes) during the welding process.
Rotating the welding port is to rotate the welding port during the welding process so that the welder can perform welding in an ideal position (horizontal, vertical, upward, or downward).
The fixed welding joint means that the pipe does not move, and the welder performs all-round welding, especially when the welding method is overhead, the welding method is not easy to operate, the welder’s technical requirements are high, and defects are prone to occur. Usually, the construction is on the pipe gallery;
The rotating port is a pipe that can be rotated. The welding position is flat welding or vertical welding. The welding operation is convenient and there are few defects. It is constructed on the ground or the floor.
In general, we use the fixed port as the active port. The active port is the prefabricated welding joint of the steel pipe, and the pipe section can be moved or rotated when the steel pipe is prefabricated outside the site. The fixed port is a welded joint installed on site, and the steel pipe cannot be moved or rotated at this time.
