Title: METHOD FOR USE IN DOUBLE-WIRE AUTOMATIC WELDING OF VERTICAL FILLET
Abstract:
A method for use in the double-wire automatic welding of a vertical fillet: using two vertically arranged welding guns when welding to simultaneously weld a vertical fillet welding seam, wherein the top welding gun is responsible for priming to ensure the fusion of welding seam base points, while the bottom welding gun is responsible for swing capping to ensure the size of the welding seam and a good formation, thereby achieving the high-efficiency automatic welding of a vertical fillet welding seam of a ship structure having a fillet weld size of 10-14 mm, and effectively reducing the time and labor intensity in the grinding of vertical fillet welding seam welding during ship manufacturing, and improving the efficiency and quality of vertical fillet welding seam welding.
