摘要
介绍低合金高强度钢压力容器焊接过程和焊后常出现的缺陷,分析其产生的因素,并从焊接前准备、焊接过程、焊接后检验三个方面对低合金高强度钢压力容器焊接接头的质量进行控制。
The flaws of low-alloy high-strength steel pressure vessel were introduced, which ffeqnently occur in the course of welding and after the welding has been finished. And the main factors that eausing clefeets were analyzed. The quality of the welding joint was eontrollecl through three aspeets： making preparation prior to welding, the proeess of welding and postweld test.
