A high-efficiency double-wire submerged-arc welding method for composite plate assembly

Abstract

The application discloses a kind of composite board group blank high-efficiency double wire submerged arc welding methods, it is related to composite board production technical field, and double wire submerged arc welding is sealed to the strip welding of composite board group blank, welding current is controlled at 1000A-1300A, the welding depth of composite board group blank is controlled at 8mm-10mm, the size of sealing strip in the depth direction of the circumferential side gap of composite board group blank is controlled at 20mm-30mm.Effectively improve welding efficiency and reduce welding time by reasonably increasing penetration, thereby improving the overall production efficiency of composite board group blank, the present application reduces the amount of weld filling by reducing the welding depth, which can save welding materials, reduce production cost and improve economic efficiency of enterprises.On the other hand, the size of the sealing strip is increased to 20mm-30mm, specifically the size of the sealing strip in the depth direction of the circumferential side gap of the composite board group blank, which improves the risk of the sealing strip being welded through under large penetration welding.
