摘　　要：分别采用手工电弧焊及埋弧自动焊两种焊接方法,研究了焊接线能量对 800 MPa 级高强钢 WEL TEN80A的焊接接头性能的影响规律,并确定了其板厚分别为20 mm和40 mm的焊接最佳线能量范围。The law that the welding line energy influences the mechanical performance of welding joint of the 800MPa scale high strength steel, WEL-TEN80A steel, was researched by adopting two welding methods, shielded metal arc welding and submerged arc welding. The best line energy range for being 20mm and 40mm thickness is determined.
