摘要
Abstract
Friction stir welding was carried out on 2mm thick 30CrMnSiA high-strength steel in different heat treatment states.The welding parameters are as follows:rotation speed is 250r/min,welding speed is 30mm/min.The test plates were subjected to pre-welding heat treatment,post-welding heat treatment and non-heat treatment.The results show that heat treatment can significantly improve the mechanical properties of welded joints.Especially the pre-welding heat treatment process,the pre-weld heat treatment process results in a high-strength martensitic organization with the smallest pre-weld grain size of any process under the same conditions,which results in higher strengths in tensile tests;The post-weld heat treatment due to the more plastic ferrite,can also show high tensile strength.关键词
