摘要
阐述了16MnR低合金钢板-板对接立焊单面焊双面成形的打底焊、填充焊、盖面焊的工艺过程及操作要领。重点讨论了提高单面焊双面成形打底焊质量的措施;强调了焊条伸入坡口的相对深度对打底焊、填充焊和盖面焊焊缝高度的重要影响。
The welding technology of one-sided welding with back formation of 16MnR steel was for vertical position welding introduced such as backing weld, multi-pass welding, cosmetic welding, and the measures emphatically how to enhance weld quality of backing weld of one-side welding with back formation were discussed. The influences of coverer eleccrode distance on backing weld, multi-pass welding as well as the throat depth of cosmetic welding were emphasized respectively.
