This International Standard specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of electrode core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels. This International Standard is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type. a) Clauses, subclauses, and tables which carry the suffix letter “A” are applicable only to products classified using the system based upon nominal composition. b) Clauses, subclauses, and tables which carry the suffix letter “B” are applicable only to products classified using the system based upon alloy type. c) Clauses, subclauses, and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all tubular cored electrodes classified in accordance with this International Standard. It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current. However, this International Standard does not use pulsed current for determining the electrode classification.

答:用纯钨或活化钨(钍钨、铈钨、锆钨、镧钨)作为不熔化电极的惰性气体保护电弧焊,简称TIG焊。15.什么叫SMAW(焊条电弧焊)焊接? 答:用手工操纵焊条进行焊接的电弧焊方法。 16.什么叫碳弧气刨? 答:使用碳棒作为电极,与工件间产生电弧,用压缩空气(压力0.5~0.7MPa)将熔化金属吹除的一种表面加工的方法。常用来焊缝清根、刨坡口、返修缺陷等。 17.为什么CO2焊比焊条电弧焊效率高?...
4钨极气体保护电弧焊 这是一种不熔化极气体保护电弧焊,是利用钨极和工件之间的电弧使金属熔化而形成焊缝的。焊接过程中钨极不熔化,只起电极的作用。同时由焊炬的喷嘴送进氩气或氦气作保护。还可根据需要另外添加金属。在国际上通称为TIG焊。 钨极气体保护电弧焊由于能很好地控制热输入,所以它是连接薄板金属和打底焊的一种极好方法。...
