摘要
Abstract
In order to solve the problems of low performance and easy strip breaking of the laser weld-ing seam of hot-rolled DP980 in cold rolling production,the laser welding experiments of hot-rolled DP980 were developed by using the methods of wire filling and post heat treatment,and the technological methods to improve the properties of welding seam were explored.The results show that the properties of hot-rolled DP980 weld can be greatly improved by increasing the post-weld heat treatment temperature.Wire filling has little effect on the weld properties of hot-rolled DP980,and is mainly used to improve the depression of weld gap.关键词
