Described in the article are the advantages and the flows of SAWH pre-welding and finalwelding processes. Focusing on the facilities located in the coil preparation station, the pre-welding area, the run-off area and the final-welding area, applications of all the major technologies as employed by the operation line are detailed from different point of view, involving a number of advanced technologies, namely, the human-machine interface technology, the PLC technology, the network architecture technology, and the servo-drive technology as well as the technology for identification and tracking of steel pipe information, etc. These technologies are closely related, which ensures that the pre-welding and final-welding line is operated with high speed, high product quality and high stability. Therefore it is expected to further realize the objectives concerning SAWH pipe production, i.e., low consumption, high operation speed and high product quality.
