双丝埋弧焊焊接工艺参数对焊缝成形的影响
Study on parameters of twin-wire submerged arc welding process to impact the weld shape and quality
摘要
Abstract
A detailed study of how twin-wire submerged arc welding process to impact the welding forming quality on low alloy high strength steel.The experimental results show that when welding current and voltage is certain ,double-wire with a change from two-wire serial,parallel to the staggered approach,from analysis of forming and mechanical properties of welding joint,only dual-wire submerged arc welding process of the two-wire serial is adapt to butt welding for low-alloy high-strength steel;To ensure that the joints forming quality, double-wire spacing, welding speed and welding current, voltage should be controlled within reasonable range;General ,when a high welding speed is used ,distance between pairs of wire should be selected smaller,while when welding speed is in the middle, the two-wire spacing should be controlled at the range of 20~100 mm;at the same time,welding speed should be controlled at 60~100 cm/min.The results has a certain reference value to the study of the multi-wire welding process and the welding of other types steel.关键词
