Default |清大圣科气化炉反骗子.|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。×&t imes;清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大金桥 ×清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn&t imes;清大圣科科技有限公司××
还可根据需要另外添加金属。××清大圣科×清大圣科电焊条&time s;清大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气 化炉×www.qhsk.cn×清大圣科科技有限公司×&times ;在国际上通称 为TIG焊。××清大圣科×清大圣科电焊条×清大圣科电 焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉&time s;www.qhsk.cn×清大圣科科技有限公司××
这种方法几乎 可以用于所有金属的连接,尤其适用于焊接铝、镁这些能形成难熔氧化物的金属以及象钛和锆这些活泼金属。&t imes;×清大圣科×清大圣科电焊条×清大圣科电焊条设备&tim es;清大金桥×清大金桥电焊条设备×清大圣科气化炉×www.qh sk.cn×清大圣科科技有限公司××这 种焊接方法的焊缝质量高,但与其它电弧焊相比,其焊接速度较慢。××清大圣科&t imes;清大圣科电焊条×清大圣科电焊条设备×清大金桥×清大金桥 电焊条设备×清大圣科气化炉×www.qhsk.cn×清大圣科科技 有限公司××
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。× ×清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大 金桥×清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn ×清大圣科科技有限公司××
焊接过程中钨极不 熔化,只起电极的作用。××清大圣科×清大圣科电焊条× 清大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉 ×www.qhsk.cn×清大圣科科技有限公司××同 时由焊炬的喷嘴送进氩气或氦气作保护。××清大圣科×清大圣科电焊条 ×清大圣科电焊条设备×清大金桥×清大金桥电焊条设备× 清大圣科气化炉×www.qhsk.cn×清大圣科科技有限公司×& times;
由于药皮容易受潮,受潮后的焊条工艺性能变坏,而且水分中的氢容易使焊缝产生气孔和裂纹,故焊条使用前必须 烘干,以降低焊条的含氢量,一般采用350~450o,保温1~2小时,烘干。×&times ;清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大金桥&tim es;清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn&times ;清大圣科科技有限公司××
