起重机械焊接工艺评定相关标准对比分析与应用

Comparative analysis and application of related standards on welding procedure qualification of hoisting machinery

针对起重机械没有焊接工艺评定标准的现状,对比分析了《钢结构焊接规范》"6焊接工艺评定"、《建筑钢结构焊接技术规程》"5焊接工艺评定"及《承压设备焊接工艺评定》的相关内容,结合起重机械焊接接头的形式、受力特点及使用性能的要求,提出最适合起重机械焊接工艺评定的参照标准并进行实例分析。

In view of the current situation where there is no standard on welding procedure qualification of hoisting machinery, comparative analysis is performed on ＂6. Welding procedure evaluation＂ in Structural Welding Code-Steel, ＂5. Welding procedure evaluation＂ in Technical specification for Welding of Steel Structure of Buildings, and Welding Procedure Qualification for Pressure Equipment. The paper introduces the reference standard for welding procedure qualification of hoisting machinery and analyzes the example in terms of the weld joint type, loading feature, and operation perform- ance of the hoisting machinery.
