本规范介绍了最低制造、设备和工艺程序要求，以及检查 钢、不锈钢、铜、铜合金和耐热或耐腐蚀材料的焊炬钎焊要求 合金和其他可充分进行焊炬钎焊的材料（AWS中介绍了铝合金的焊炬钎焊 C3。7M/C3。7，铝钎焊规范）。本规范提供了对焊炬钎焊接头进行分类的标准 基于载荷和故障后果以及质量保证标准，定义了每种情况下的可接受极限 班本规范规定了可接受的焊炬钎焊设备、材料和程序，以及所需的 每类接头的检查。

This specification presents the minimum fabrication, equipment, and process procedure requirements, as well as inspection requirements for the torch brazing of steels, stainless steels, copper, copper alloys, and heat- or corrosion-resistant alloys and other materials that can be adequately torch brazed (the torch brazing of aluminum alloys is addressed in AWS C3.7M/C3.7,Specification for Aluminum Brazing). This specification provides criteria for classifying torch brazed joints based on loading and the consequences of failure and quality assurance criteria defining the limits of acceptability in each class. The specification defines acceptable torch brazing equipment, materials, and procedures as well as the required inspection for each class of joint.
