    • PROBLEM TO BE SOLVED: To suppress weld defects such as blow hole caused by the gasification of a coating material between coated steel plates at the welding time without needing troublesome and difficult gap control. SOLUTION: In the lap welding method for galvanized steel plates 1, Cu-base filler metal 4 as a low melting point filler metal is mixed into fused pool 7. In this way, the temperature at the portion in contact with galvanized layers 2 between both steel plates 1 being the outer peripheral zone in the fused pool 7 is controlled to not higher than the boiling point of Zn. The Zn in the galvanized layer in contact with the outermost periphery of the fused pool 7 is only melted and not boiled. Therefore, gas volume produced by gasifying the galvanized layer 2 between both steel plates 1 is reduced and thus, the gas volume invaded into the fused pool 7 can be reduced. Further, since the advancing direction of Zn vapor in the fused pool 7 is obstructed with the welded part 6 formed by quickly solidifying the fused pool 7, the Zn vapor quickly gets out from the fused pool 7 without beingnot stayed in the fused pool 7.

    • 要解决的问题:为了抑制在焊接时间期间由涂覆钢板之间的涂层材料气化引起的气泡孔等焊接缺陷,而不需要麻烦和困难的间隙控制。 解决方案:在镀锌钢板1的搭接焊接方法中,将作为低熔点填充金属的Cu基填充金属4混入熔池7.以这种方式,与镀锌层接触的部分的温度 将作为熔池7的外周区域的两个钢板1之间的温度控制在不高于Zn的沸点。 与熔池7的最外周接触的镀锌层中的Zn仅熔化而不沸腾。 因此,通过使镀锌层2在两钢板1之间气化而产生的气体体积减少,因此能够降低侵入熔池7的气体体积。 此外,由于熔融池7中的Zn蒸汽的前进方向被熔融部7快速凝固而形成的焊接部6阻塞,所以不会将熔融池7从蒸发池7中快速地从熔池7中排出。 版权所有(C)2006,JPO&NCIPI

      SOLUTION: In a laser beam welding method, a low melting point material 1 having the melting point lower than that of a member W2 to be welded is covered on a surface of the member W2, and the surface of the member W2 is irradiated with laser beam LB to measure at least one of the molten length and the molten area of the low melting point material 1, and the output of the laser beam LB is controlled while determining whether or not the heat input in the member W2 is adequate, based on at least one of the molten length and the molten area. The image of the surface of the member W2 irradiated with the laser beam LB is picked up by an image pickup means. By computing the image data obtained from the image pickup means 2, at least one of the molten length and the molten area of the low melting point material 1 is measured.
