This Internatioanl Standard specifies requirements for classification of wire electrodes and weld deposits in the as-welded condition and in the post weld heat-treated condition for gas shielded metal arc welding of non alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One wire electrode can be tested and classified with different shielding gases. This International Standard constitutes a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal. a) Clauses and tables which carry the suffix letter "A" are applicable only to wire electrodes classified to the system based upon the yeild strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard. b) Clauses and tables which carry the suffix letter "B" are applicable only to wire electrodes classified to the system based upon the yeild strength and the average impact energy of 27 J of all-weld metal in accordance with this International Standard. c) Clauses and tables which have neither the suffix letter "A" or the suffix letter "B" are applicable to all wire electrodes classified to the system based upon the yeild strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard.

焊接材料:保护气体、钨极 适用范围:广泛用于工业生产,特别是航空航天等军工和尖端工业技术所用的铜及铜合金、钛及钛合金、合金钢、不锈钢、钼等金属的焊接,如钛合金的导弹壳体,飞机上的一些薄壁容器等。6 管状焊丝电弧焊 管状焊丝电弧焊也是利用连续送进的焊丝与工件之间燃烧的电弧为热源来进行焊接的,可以认为是熔化极气体保护焊的一种类型。所使用的焊丝是管状焊丝,管内装有各种组分的焊剂。...
二、GB/T8110-2008焊丝力学 1、检测用于气体保护电弧焊用碳钢; 2、低合金钢实心焊丝和填充丝的抗拉强度; 3、屈服强度; 4、伸长率等指标。...
答:(1)CO2焊比焊条电弧焊熔化速度和熔化系数高1~3倍; (2)坡口截面比焊条减小50%,熔敷金属量减少1/2; (3)辅助时间是焊条电弧焊的50%。 三项合计:CO2焊的工效与焊条电弧焊相比提高倍数2.02~3.88倍。 18.为什么CO2焊接接头比焊条电弧焊的焊接接头质量好?...
