    摘要： The present invention relates to an exothermic cutting electrode. The electrode includes an outer hollow conductor, an inner conductor disposed inside the and outer hollow conductor. The inner conductor is configured so as to form the boundaries of two chambers and configured to form a third chamber between the outer hollow conductor and an inner conductor. The three chambers are of substantially equal cross-sectional size whereby even gas flow is proudced and even consumption of the electrode is provided.

    摘要： The contact wire (30) for a roller seam welding machine is provided on its front face with grooves (32) which are formed in the longitudinal direction of the wire and which are bounded by sharp longitudinal edges (34). The contact wire (30) is particularly well suited for welding metal sheets, the surfaces of which are heavily soiled or provided with coatings which are poor electrical conductors or electrically non-conducting. During the welding operation, the longitudinal edges (34) cut open the sheets to be welded or their oxide layer or coating which is a poor electrical conductor or non-conducting, and render possible a direct passage of the welding current to the actual metal sheet. Dirt as well as semi-plastic and vaporized coating material are reliably carried away to the front and rear in the longitudinal grooves so that the contact wire (30) cannot "float" during the welding operation. A preferred application for the contact wire (30) is the welding of fuel tanks from sheets which are coated so as to be poor electrical conductors or non-conducting on both sides, on a resistance roller seam welding machine.

    摘要翻译： 用于辊缝焊机的接触线（30）在其前表面上设置有沿着线的纵向方向形成并且由锐利的纵向边缘（34）限定的凹槽（32）。 接触线（30）特别适用于焊接金属片，其表面严重污染或设置有不良电导体或不导电的涂层。 在焊接操作期间，纵向边缘（34）切割要焊接的片材或其氧化物层或涂层，其是不良的导电体或不导电的，并且使焊接电流直接通过实际的金属片 。 污物以及半塑料和汽化涂层材料可靠地在纵向槽中前后移动，使得接触线（30）在焊接操作期间不能“浮动”。 用于接触导线（30）的优选应用是在电阻辊缝焊机上将燃料箱从被涂覆为不良电导体或两侧不导电的片材焊接。
