In the automatic welding process of pressure vessel automatic welding equipment, the wrong operation or unexpected situation may lead to some problems in the welding process, so it may lead to serious consequences if it is not solved in time. Below by the small ribbon you in the process of automatic welding simple fault processing

1.在焊接過程中，發現電弧在噴嘴和工件之間產生，這樣就產生了雙弧現象。出現此現象后，要及時的調節焊接參數電流和離子氣，電流過大和離子氣過小都會引起雙弧。

1. In the welding process, it is found that the arc is generated between the nozzle and the workpiece, which leads to the double arc phenomenon. After this phenomenon, the welding parameters current and ion gas should be adjusted in time, too much current and too little ion gas will cause double arc.

2.焊接時發現等離子焊槍噴嘴處冒煙。要停止焊接，檢查水箱是否打開，水表有無水量顯示，如果沒有水通過焊槍，則焊槍已燒壞，須人士來修理。

2. Smoke was found at the nozzle of plasma welding gun during welding. To stop welding, check whether the water tank is open and whether the water meter shows the amount of water. If there is no water passing through the welding gun, the welding gun is burnt out and needs to be repaired by professionals.

3.在鎢對中的過程中，不打高頻。出現這種情況，要及時清理火嘴，用金相砂紙將金屬磨出光澤，重新磨鎢針。

3. In the process of tungsten alignment, high frequency is not used. In this case, the nozzle should be cleaned in time, the metal should be polished with metallographic sandpaper, and the tungsten needle should be ground again.

4.焊縫中產生氣孔。產生的原因可能是母材有油、銹等污物；氣體保護效果差；氣路不干凈；槍頭漏氣。應該清理工件，降低弧壓，焊速降低，換用新的氣體，更新管路，更換O型圈。

4. There are pores in the weld. The reasons may be that the base metal has oil, rust and other dirt; the gas protection effect is poor; the gas path is not clean; the gun head leaks. The workpiece should be cleaned, the arc voltage should be reduced, the welding speed should be reduced, the new gas should be used, the pipeline should be renewed, and the O-ring should be replaced.
