摘要
1Cr17不锈钢管与Q235钢管的焊接属于异种钢焊接,焊接接头容易出现裂纹缺陷。通过认真分析,选用合适的焊接工艺并进行适当的焊后热处理,且采用单面焊双面成形是可以避免裂纹缺陷的产生,获得很好的焊接质量。
The 1Cr17 stainless steel pipe and Q235 steel pipe welding belongs to the heterogeneous steel welding, the weld joint easy to have the crack flaw. Through the earnest analysis, after selecting the appropriate welding craft and carries on suitably welds the heat treatment. Also uses one - sided welds two- sided takes shape is may avoid the crack flaw the production, obtains a very good welding quality.
