Fixed welding is a welding joint that cannot move after the steel pipe is assembled. During the welding process, the welding position changes (horizontally, vertically, upward, and inward).
Rotating the welding port means rotating 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 welding upward, the welding method is difficult to operate, requires high technical requirements for the welder, and is prone to defects. It is usually constructed on a pipe gallery;
The rotary port allows the pipe to rotate, and the welding position is flat welding or vertical welding. The welding operation is convenient and has few defects. It is constructed on the ground or floor.
Under normal circumstances, we use the fixed port as a movable port. The movable joint is a prefabricated welded joint of the steel pipe. The pipe section can be moved or rotated when the steel pipe is prefabricated off-site. The fixed port is a welded port installed on site. At this time, the steel pipe cannot move or rotate.
