摘要
Abstract
Aiming at the problem of low welding efficiency and urgent need to improve the joint quality of ship thick plate,a new process of cable-type 36-wire submerged arc welding is proposed and developed in this paper.The process uses ⌀7.0 mm cable-type wire,which is made up of ⌀1.0 mm central wire and 35 peripheral wires.During the welding process,mul-tiple wires are melted synchronously by continuous wire feeding,and the end of the peripheral wire forms an autonomous ro-tating welding arc.Based on the modular inverter welding machine,the process test was carried out and compared with the traditional ⌀4.0 mm single wire submerged arc welding.This process significantly improves the welding efficiency and joint quality.The deposition speed is increased by about 60%,the welding time is shortened by 50%and the electric energy is saved by 20%under the same wire consumption.The average tensile strength of the weld joint reaches 542 MPa,and the elongation is 25.02%.The microstructure is mainly composed of fine-grained ferrite and pearlite,and no harmful phases such as widmanstatten structure appear.The comprehensive mechanical properties and weld quality are significantly better than those of traditional single-wire submerged arc welded joints.关键词
