摘要
以P690QL1调质高强钢板为研究对象,选择国产和进口两种焊材,分别采用手工电弧焊和埋弧自动焊方法,焊后对焊接接头进行力学性能检验和分析,最终确定了适合P690QL1钢的焊接工艺规范。
Taking P690QL1 quenched and tempered high strength steel plate as research object, two welding materials from home and abroad have been selected, manual arc welding and automatic submerged arc welding methods have been tried, mechanical properties of weld joint have been tested and analyzed after welding. Proper welding process specification of P690QL1 steel plate has been determined
