摘要：
An abutting end portions of the strips are heated from below to a temperature range where annealing effects are obtained by means of a movable heating apparatus which performs high-frequency induction heating and a laser beam (or arc or electron beam) is irradiated from above, at the same speed as that of the movable heating apparatus, to laser beam weld (or arc or electron beam weld) the abutting end portions.
