补充资料：焊接:气焊
     利用气体燃烧的火焰作为热源的焊接方法(见图 气焊示意图 )。乙炔 (C2H2)是最常用的可燃气体。氧和乙炔燃烧的化学过程是 2C2H2+SO2→4CO+2H2+3O2+热量→4CO2+2H2O+热量。形成的火焰可调节成4种形式﹐分别适用於不同金属和合金的焊接(见表 氧乙炔火焰的形式及其应用 )。氧乙炔火焰生成的氢和二氧化碳对熔化金属有一定的保护作用。气焊一般是手工操作﹐常用於焊接 6毫米以下的薄板和小直径管材以及修补焊接。 
      气焊适用於多种金属材料的焊接﹐设备简单﹑成本低廉﹑焊炬操作灵便﹐在小批量薄件(最薄 0.5毫米)焊接﹑全位置安装焊(如锅炉低压管安装)和修补焊等方面应用较普遍。
