Structural Welding Code — Steel
7. Stud Welding 螺柱焊
Scope 范围
Section 7 contains general requirements for welding of steel studs to steel, and stipulates specific requirements: 第 7 章包括将钢螺柱焊於钢材的一般要求,并规定了特定要求: (1) For workmanship, preproduction testing, operator qualification, and application qualification testing when required, all to be performed by the Contractor 工艺,生产前试验,操作人员资格评定以及应用评定试验,如果需要,则全由承包商实施. (2) For fabrication/erection and verification inspection of stud welding during production 生产过程中螺柱焊接的作业,安装和监造检查. (3) For mechanical properties of steel studs, and requirements for qualification of stud bases, all tests and documentation to be furnished by the stud manufacturer 钢螺柱的力学性能,螺柱焊接端的评定要求,由螺柱制造商提供的所有试验和文件. Note: Approved steels; for studs, see ; for base metals, see Table (Groups I and II). For guidance, see . 注:认可的钢材:有关螺柱的见 ;有关母材的见表 (I 组和 II 组).参见 的指导.
Scope 范围
Stud welding is unique among the approved welding processes in this code in that not only are the arc length and the weld time automatically controlled, but it also lends itself to a significant production proof test. Once the equipment is properly set, the process is capable of a large number of identical sound welds when attention is given to proper workmanship and techniques. Many millions of studs have been essfully applied. For other reasons outlined above, formal procedure qualifications are not required when studs are welded in the flat (downhand) position to materials listed in Table , Group I and II. Procedures developed under the application qualification requirements of are an exception to the foregoing. Since this constitutes the basic change from other approved
welding processes in this code, stud welding has been moved to Section 7. 螺柱焊是本规范认可的焊接方法中一种独特的焊接方法,它不仅弧长和焊接时间自动控制,,只要注意恰当的工艺和技术,, I 组和 II组材料上以平焊位置(向下)进行时, 条款应用评定要求发展的工艺是上述的一种例外.
