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(guò)程中，發(fā)現(xiàn)電弧在噴嘴和工件之間產(chǎn)生，這樣就產(chǎn)生了雙弧現(xiàn)象。出現(xiàn)此現(xiàn)象后，要及時(shí)的調(diào)節(jié)焊接參數(shù)電流和離子氣，電流過(guò)大和離子氣過(guò)小都會(huì)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(shí)發(fā)現(xiàn)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(wú)水量顯示，如果沒(méi)有水通過(guò)焊槍，則焊槍已燒壞，須人士來(lái)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(duì)中的過(guò)程中，不打高頻。出現(xiàn)這種情況，要及時(shí)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(chǎn)生氣孔。產(chǎn)生的原因可能是母材有油、銹等污物；氣體保護(hù)效果差；氣路不干凈；槍頭漏氣。應(yīng)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.
