Narrow-Gap Submerged-Arc Welding With a Multiple-Wire Electrode
J. Tušek
Sažetak
The article treats a completely new variant of narrow gap welding. First, nine different welding heads for narrow gap welding are described and shown schematically. The core of the article is devoted to a description and schematic representation of a unit for welding with twin-wire and triple-wire electrodes respectively and a description of technology for narrow-gap submerged-arc welding of thick workpieces. A macrograph of the weld is shown too, and basic optimum welding parameters for attaining a quality weld are given. Finally, main advantages of multiple-wire narrow-gap submerged-arc welding are stated.
