摘要
主要介绍了工业汽轮机汽缸与阀体的组焊工艺，详细说明了汽缸与阀体对接的接头形式、组对要求、焊接顺序及焊接工艺评定。施工实践表明，只要采用合理的接头形式和焊接工艺，并进行严格的焊后检验，完全可以保证组焊的焊接质量。
The composite welding of the outer casing and valve in industrial steam turbine was introduced, and the type of the welding joint, composition requirement, PQR about the casing and valve was described. Adopting corresponding groove, welding method, welding process and strict inspection after PWHT, which could guarantee the quality of weld.
