摘要
选取20G作为实验材料,采用埋弧自动焊焊接成试板,分别考察了焊接电流和焊接速度这两个焊接工艺参数对其焊接残余应力数值大小的影响。结果表明,焊接电流一定时,焊接残余拉应力随焊接速度增大而增大;焊接速度一定时,焊接电流越大,焊接残余拉应力越大。
Selecting 20G as experimental material,the effect of welding current and welding speed on welding residual stress were studied by using submerged arc welding.The results show that when the welding current is definite,the welding residual stress increases with the increase of welding speed,when the welding speed is definite,the welding residual stress increases with the increase of welding current.
