This International Standard specifies requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of non-alloy and fine grain steels in the as-welded condition or in the post-weld heat-treated condition with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if any. This International Standard is 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. 1) Paragraphs and tables which carry the suffix letter “A” are applicable only to tubular cored electrodes classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard. 2) Paragraphs and tables which carry the suffix letter “B” are applicable only to tubular cored electrodes classified to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in accordance with this International Standard. 3) Paragraphs and tables which have neither the suffix letter “A” nor 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, but for the purposes of this International Standard, pulsed current is not permitted for determining the electrode classification.
二、氩弧焊接氩弧焊接是电弧焊的一种,主要是利用连续送进的焊丝与工件之间燃烧的电弧作热源,由焊炬喷嘴喷出的气体保护电弧来进行焊接的。目前氩弧焊接是常用的方法,可适用于大部分主要金属,包括碳钢、合金钢。熔化极惰性气体保护焊适用于不锈钢、铝、镁、铜、钛、锆及镍合金,由于价格低,被广泛用于模具修复焊,但焊接热影响面积大、焊点大等缺点,目前在精密模具修补方面已逐步补激光焊所代替。...
工件易变形,电阻焊通过接头两边焊合,而激光焊只从单边进行,电阻焊所用电极需经常维护以清除氧化物和从工件粘连着的金属,激光焊接薄金属搭接接头时并不接触工件,再者光束还可进入常规焊难以焊及的区域,焊接速度快。 氩弧焊 使用非消耗电极与保护气体,常用来焊接薄工件,但焊接速度较慢,且热输入比激光焊大很多,易产生变形。 ...
在工业装置中气体的液化、液化气体的生产、储运和应用日趋广泛,低温技术的发展促进了各种低温压力容器的运用。低温压力容器设计较常温容器设计复杂,笔者就低温压力容器的使用特点及存在的的失效模式,设计时低温压力容器的选材、结构设计和制造工艺检验应注意的事项作了分类分析,为在工作中低温压力容器设计给予更多的参考。 ...
