手工电弧焊、埋弧焊、TIG焊、CO2保护焊等各种焊接方法的优缺点

压力容器的承压能力和安全可靠性,在很大程度上取决于容器的制造质量。焊接是现代压力容器制造中常用的加工方法,也是关键的工艺手段。所以合格的焊接质量是保证压力容器的强度和安全可靠性的前提和基础。在压力容器制造过程中常用的焊接方法有手工电弧焊、埋弧焊、TIG焊、CO2保护焊等方法。下面分别介绍:

手工电弧焊/埋弧焊/TIG焊/CO2保护焊等各种焊接方法的优缺点

1、  手工电弧焊

4、  CO2保护焊

利用CO2气体在高温下分解为CO和O2,氧分子继续分解为氧原子,原子氧有强烈的氧化作用,氧化熔池中的Fe、Si、Mn、C等元素,形成相应的氧化物FeO、SiO2、MnO、CO等。产生的SiO2、MnO以熔渣的形式浮出,CO逸出到气相中。

CO2保护焊的缺点是:焊缝成型粗糙,飞溅较大,弧光强烈及紫外线强分别为手工电弧焊的2~3倍和20~40倍。应加强防护。
