火焰矫正对屈服强度900MPa级低合金高强钢焊接接头组织与性能的影响
Influence of flame correction on microstructure and properties of welded joints of 900 MPa class yield high-strength and low-alloy steel
摘要
Abstract
When welded joints of 900 MPa class yield high-strength and low-alloy steels are flame heated to 700 ℃,a lot of M-A are found in the welding heat affected zone.The strength of the welded joints does not change basically,but the low temperature impact toughness of the welding heat affected zone declines by 45.3％.The results show that mechanical correction is more suitable for high-strength and low-alloy steel than flame correction.It is necessary to control the heating temperature if using flame correction.关键词
