    • A hybrid welding apparatus for subjecting a base metal to gas-shielded arc welding and laser welding comprises a laser generator for emitting a laser beam and a condenser optical system for condensing the laser beam to laser weld the base metal. The condenser optical system includes a plurality of lenses, each having a hole portion in the center thereof. A tubular supply holder for supplying a welding wire is passed through these respective hole portions of the lenses and located substantially coaxially with the axis of the condenser optical system. The laser beam and welding wire to be applied to the base metal are arranged coaxially, so that laser-welding and arc-shielded welding can be simultaneously performed with a wide angle between the welding head and a bevel of the base metal, thereby deepening penetration of the weld at an increased welding speed.
    • 用于对母材进行气体保护电弧焊和激光焊接的混合焊接装置包括用于发射激光束的激光发生器和用于使激光束聚光以激光焊接母材的聚光器光学系统。 聚光镜系统包括多个透镜,每个透镜在其中心具有孔部分。 用于供应焊丝的管状供应保持器穿过透镜的这些相应的孔部分,并且与冷凝器光学系统的轴线基本同轴地定位。 施加到母材的激光束和焊丝同轴地布置,从而能够以焊接头与母材的斜面之间的广角同时进行激光焊接和电弧保护焊接,从而加深穿透 的焊接速度。
