Abstract

The invention relates to a metal welding wire manufacture method, especially to an aluminum alloy welding wire surface scraping method and device, which mainly solves problems in prior art that welding wire surface is treated by a chemical treatment method, because after chemical treatment, surface smoothness is deficient, block is easy to happen when conveying, simultaneously oil stain and chemical stain are remained on the surface, smoke is generated when the welding wire is used for welding, and black spot and splash phenomenon are appeared on and near weld seam. The method includes steps of line laying, positioning, wiping, crude scraping, fine scraping and cooling. The device includes a frame, and a positioning wheel, a wiping die, a crude scraping die, a fine scraping die and a cooling device which are connected in the frame.

Description

technical field [0001] The invention relates to a method for manufacturing a metal welding wire, in particular to a method and equipment for scraping the surface of an aluminum alloy welding wire. Background technique [0002] Aluminum alloy welding wire is usually transported by automatic welding machine. In order to ensure the smooth feeding of the wire and overcome the impurity on the surface of the welding wire that affects the welding performance, the welding wire must undergo surface treatment before coiling and packaging to achieve smoothness and cleanliness of the welding wire. The Chinese patent discloses a high-strength aluminum alloy welding wire and its preparation method (notification number: CN 1943962A). The steps are: using aluminum ingots, copper ingots, sponge titanium, boric acid, and crystalline silicon as raw materials, preparing materials; Use medium or high frequency induction furnace, clay graphite crucible to melt and cast ingots to prepare intermedi...
