摘要
WB36钢是在C-Mn钢基础上添加Ni、Cu、Mo及Nb微合金化的钢。通过对WB36钢的化学成分和焊接性能特点进行分析，确定了焊接工艺方案，并进行了焊接工艺评定。在选择合适的焊接材料基础上，焊前预热150℃～200℃，焊后进行200℃～250℃的紧急后热，并采用580℃～620℃的焊后热处理制度。该工艺成功地应用于高压厚壁集箱生产中。
WB36 is created by adding Ni ,Cu,Mo and Nb on the base of C-Mn steel. This paper analyzes the chemical proportion and welding properties of WB36, defines welding method, processes welding program quality assess. After selecting the fit welding material ,fore-welding heating is 150℃ -200℃ ,urgent post heat-treatment is 200℃ -250℃ ,postwelding heat-treatment is 580℃-620℃ ,the procedure has been applied in the high pressure thick wall header production.
