摘要
通过焊前准备、焊接工艺规范、施焊过程、焊后热处理和检验分析等几个方面详细阐述了P9 1钢的焊接工艺。该工艺操作简便,减少了焊接缺陷,提高了焊接速度和焊接质量。
Welding technics of P91 steel are expounded, including preparation before welding, welding technics criterion, welding process, heat treatment after welding and inspection inspectron analysis. The operation of this technics is easy, welding defects are reduced, the welding rate and quantity are raised.
