WELDING APPARATUS FOR BRANCHED TUBE

摘要

The present invention enables a first and a second welding torch (112a), (114a) to be positioned in a symmetrical state having a predetermined distance on the same line. Front ends of each welding torch (112a), (114a) are positioned at the predetermined distance from the center of a paper pipe and a branch pipe (14) to the both sides so as to enable a circular circumference where the paper pipe and the branch pipe (14) come in contact with each other to be welded while an apparatus rotates 181 degrees in order to improve continuous workability and a welding quality.
