The invention discloses a special-shaped spiral welding wire and a manufacturing method thereof. The special-shaped spiral welding wire comprises a welding wire body, a center column is arranged in the welding wire body, a plurality of evenly-distributed grooves are formed in the welding wire body, and the welding wire body is of a spiral structure around the center column. The production device comprises a pay-off mechanism, the wire outlet end of the pay-off mechanism is matched with a traction mechanism, a blooming mechanism, a finish rolling mechanism and a sizing die structure are sequentially arranged between the pay-off mechanism and the traction mechanism, the wire outlet end of the traction mechanism is matched with a wire accumulating mechanism, and the wire outlet end of the wire accumulating mechanism is matched with an inward-folding twisting mechanism. The welding wire is simple in structure and low in cost. According to the production device, rolling production is adopted, and the requirement for the production environment is low; the traction mechanism pulls the welding wire to carry out primary rolling and final rolling, and rolling of the welding wire is achieved through the sizing die, and rolling is convenient and fast; and the wire accumulating mechanism carries out winding treatment on the rolled welding wires, so that the rolling effect can be better checked, and meanwhile, the welding wires which are far away from being broken can be provided for the inward rolling and twisting mechanism.
Description
technical field [0001] The invention relates to the field of welding materials and wire products and processing technology, in particular to a special-shaped spiral welding wire and a method for its production process. Background technique [0002] Welding wire is used as filler metal for metal welding, and as welding electrode material for electric arc power supply. It is widely used in gas shielded welding, submerged arc welding, electroslag welding and other metal shielded arc welding. In gas welding and gas tungsten arc welding, the welding wire is used as filler metal; in submerged arc welding, electroslag welding and other MIG arc welding, the welding wire is both filler metal and conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux. However, the production process of the existing cable-type welding wire (twisted from many thin welding wires) is complicated and the cost is high, and the combination of the existing welding wire a...
