CRRC Changchun Railway vehicles Co., Ltd. 按照合同要求,中车长客在某出口项目执行AWS D17.2/D17.2M:2013点焊标准,该标准是美国航空航天点焊标准,与现行的EN15085铁路轨道车辆焊接标准有较大的差别。从点焊工艺评定试验、设备验证试验、点焊质量判定、周期性检验等方面对AWS D17.2/D17.2M:2013点焊标准进行分析,并与国际铁路客车行业通用的EN15085焊接标准和日本点焊标准JIS E 4048进行对比,确定了AWS D17.2/D17.2M:2013点焊标准执行的重点要求,为项目的顺利实施提供了技术保障。 According to the contract requirements, our company implemented AWS D17.2/D17.2 M:2013 resistance spot welding standard in an export project, which is the American aerospace resistance spot welding standard, which is quite different from the EN15085 railway vehicle welding standard currently implemented by our company. This paper describes the AWS D17.2/D17.2 M: 2013 spot welding standard from the aspects of the resistance spot welding procedure qualification test, welding machine qualification, spot weld quality evaluation and periodic inspection, and compares it with the railway vehicle industry general EN15085 standard and Japan standard JIS E 4048. Identifies the requirements of AWS D17.2/D17.2 M: 2013 resistance spot welding standards, which provide technical guarantee for the implementation of the project. 轨道车辆 电阻点焊 焊接标准 设备验证 验收标准 railway vehicle resistance spot welding spot welding standard qualification of welding machine acceptance criteria TG453.9;U270.6 2022-03-08 9 51
