Abstract

PURPOSE: To perform continuous welding subsequently without stopping materials during continuous conveying of the materials by placing a welding machine on a welding travelling carriage which reciprocatively travels in a timing relation with respect to the conveying of the materials and performing welding during the travelling synchronized to the material conveyance.

CONSTITUTION: The 1st material I on a front table 14 is carried on the inlet side table 28 provided on a welding travelling carriage 22. After the trailing end face of the material I passes the weld point X, the driving of the inlet and outlet side tables 28, 30 is stopped to stop the material I. In this state, the stopper 34 provided on the carriage 22 is moved upward up to the level hight of the material conveying path, then the table 30 is moved backward to retreat the material I and let its trailing end contact the stopper 34, after which the width direction of the material I is clamped 44. Next, the stopper 34 having been moved upward is lowered from the level height of the conveying path. Next, the material II arriving at the end part of the table 14 is conveyed up to the trailing end face of the material I by driving the table 28 on the carriage 22 through similar operation, by whidh it is contacted anc closely fitted thereto, after which the materials I, II are welded and connected by a welding machine 32. Thereafter, the succeeding materials are subsequently continuously welded by the similar operations.
