摘要
文章介绍了用自动焊和手工焊的焊接方法焊接SA516Gr70（SA240TP304L）不锈复合钢压力容器焊接工艺试验及焊接工艺评定，通过检查焊缝的化学成分、硬度、金相组织、测定接头的力学性能，晶间腐蚀等试验，证明了焊接方法及焊材的可行性，对不锈钢复合钢压力容器的焊接要点进行了简要说明。
The paper introduces in brief the shielded metal arc welding and shielded metal welding procedure test and procedure qualification of SA516Gr70 （SA240TF304L） stainless clad steel pressure vessel. By means of various tests on welded joint, such as chemical composition, hardness, metallographic structure, mechanical properties and intergranular corrosion of weld and so on, the results show that it is feasible to weld stainless clad steel pressure vessel using the welding procedure and the filler. The paper also introduces the main welding procedure of stainless clad steel pressure Bessel.
