Abstract

PURPOSE: To enable carrying in and out of tubes during welding by carrying in and butting the tubes to be welded between a pair of feed booms arranged to allow free advance or retreat and executing inside welding alternating the feed system.
CONSTITUTION: Inside welding is made at the beveling of steel tubes 12 using the welder 4 which is fed from the feed boom 4. At this time, the beveling of the tube 11 carried on the turning roller 5 is set to face downward and shifted to the side of the cage roll 6 by the carrying roller 7 and the ends of tubes 11, 12 are butted. Inside welding by the welder is continued extending from left end of the tube 12 to the tube 11. When butt portions of the tubes 11, 12 come to the left end of the carry out table 9, feed boom is changed to 1. Then, the butt portion is cut by the cutting saw 10 and the tube 12 is carried out. When welding of the tube 11 is made to a certain degree, the feed boom 1 is changed to feed boom 2 and welding is continued.
