AWS3.0 焊接术语摘录 注：黑体字为标准术语，中文为我自己翻译 abrasive blasting. A method of cleaning or surfacen roughening by a forcibly projected stream of abrasive particles. 喷砂 acceptable weld. A weld that meets the applicable requirements. air carbon arc cutting (CAC-A). A carbon arc cutting process variation that removes molten metal with a jet of air. 空气炭弧切割 aligned porosity. A localized array of porosity oriented in a line. 线状气孔 arc gouging. Thermal gouging that uses an arc cutting process variation to form a bevel or groove. 电 弧气刨 arc strike. A discontinuity resulting from an arc, consisting of any localized remelted metal, heat-affected metal, or change in the surface profile of any metal object. 电弧击伤 arc stud welding (SW). An arc welding process that uses an arc between a metal stud, or similar part, and the other workpiece. The process is used without filler metal, with or without shielding gas or flux, with or without partial shielding from a ceramic or graphite ferrule surrounding the stud, and with the application of pressure after the faying surfaces are sufficiently heated. 螺柱焊 arc welding electrode. A component of the welding circuit through which current is conducted and that terminates at the arc. 电弧焊电极 automatic welding. Welding with equipment that requires only occasional or no observation of the welding, and no manual adjustment of the equipment controls. Variations of this term are automatic brazing, automatic soldering, automatic thermal cutting, and automatic thermal spraying. See Figures 52 and 53 and Table 4. See also adaptive control welding, manual welding, mechanized welding, robotic welding, and semiautomatic welding. 自动焊 back bead. A weld bead resulting from a back weld pass. 背面焊 backgouging. The removal of weld metal and base metal from the weld root side of a welded joint to facilitate complete fusion and complete joint penetration upon subsequent welding from that side. 清
