The invention belongs to the technical field of pipeline
welding production lines, and particularly relates to a
titanium alloy continuous
pipe making
production line which comprises a connection
welding station and a
pipe seam welding station which are arranged in sequence. The
punching mechanism and the connection
welding mechanism arranged on the connection welding
station can alternately move to the
titanium alloy belt, the end of the
titanium alloy belt is
cut off firstly, then welding is conducted, and in the process, movement of the
titanium alloy belt is reduced, so that alignment of the connection position is guaranteed, and the connection effect and the connection welding quality are improved. The
pipe seam welding station provides a welding power source suitable for continuous welding of the ultra-long welding seam for the TIG welding gun and the
deep penetration welding gun, so that when the ultra-long welding seam with the distance of 1000-12000 m or above is continuously and uninterruptedly welded for 48-500 hours, the situation that arc stopping events are accidentally triggered, and secondary arc starting is needed is reduced, and the welding efficiency is improved. Accidental arcing accidents caused by interference of external irresistible factors such as accidental power failure are reduced, and the welding yield is guaranteed.
