    • A method for continuously producing a powder-filled tubular welding electrode, whereby a metallic band while being fed is formed to a gutter (16) and thereupon to a tube (21), whereby the edges of the gutter are welded together and welding powder is supplied via a conduit (18, 19) to the welded tube, and the welding powder free space of the tube being filled with a protective gas. The object of the invention is to provide a method for continuous production of a tubular welding electrode, especially a tubular welding electrode for welding without external supply of protective gas. The invention is characterized by the fact that the welding powder is introduced in a container (11), which is evacuated of an essential portion of its air content, whereupon the protective gas is introduced into the container until a positive pressure has been reached therein, and the powder-protective gas-mixture thereupon being supplied to the tube (21), whereby in the conduit (18, 19) is maintained a gas pressure, which is somewhat higher than the atmospheric pressure.
    • 一种用于连续生产填充粉末的管状焊接电极的方法,由此将馈送的金属带形成于沟槽(16)并随后形成管(21),由此将沟槽的边缘焊接在一起并将焊接粉末 通过管道(18,19)供应到焊接管,并且管的焊接粉末自由空间被填充有保护气体。 本发明的目的是提供一种用于连续生产管状焊接电极的方法,特别是用于在不外部供应保护气体的情况下焊接的管状焊接电极。 本发明的特征在于,焊接粉末被引入容器(11)中,该容器(11)被抽空其空气含量的主要部分,于是保护气体被引入容器中直至达到正压, 并且将所述粉末保护气体混合物供应到所述管道(21),由此在所述导管(18,19)中保持稍高于大气压力的气体压力。
