The difference between plasma gouging and carbon arc gouging:

Carbon arc gouging is a thermal processing technique that uses the arc heat generated between a carbon rod and a workpiece to melt metal, while using compressed air to blow away the melted metal and gouge grooves on the metal.

And plasma arc gouging uses high-temperature and high-speed plasma flow to heat, melt and blow away local metal!

Both plasma arc gouging and carbon arc gouging can be used for root cleaning of metal material welds, but carbon arc gouging, which uses carbon rods, will cause a certain degree of carburization on the surface of the base material after use; Moreover, the fundamental difference between plasma arc gouging and carbon arc gouging is that plasma gouging does not require carburization. Therefore, after processing, plasma gouging can eliminate the need for subsequent decarburization layers.

The energy density of plasma arc gouging is high, the arc and heat are relatively concentrated, the arc stiffness is good, and the gouging groove is relatively neat, which is conducive to automatic or manual welding in the later stage. Guns can be used for continuous operation and can be paired with semi-automatic carts or professional swing arm carts for automated air planing, thereby improving production efficiency.

At present, manual carbon arc gouging is mainly used for cleaning the roots of stainless steel materials. There are two situations where carbon arc gouging is not easy to use: one is ultra-low carbon stainless steel in contact with strong corrosive media, and the other is high-strength alloy steel thick plates that are highly sensitive to cold cracks. This is because using carbon arc gouging will result in strong carburization on the surface of the material. In order to avoid the adverse effects of carburization on welding, the carburized layer must be polished off with tools before welding.

Therefore, the superiority and promotion scope of plasma air gouging are highly commendable, and this technology will play a pivotal role in the field of root cleaning in the future!

The LGK-100J and LGK-130J series plasma arc equipment produced by Changzhou Haibeide CNC Machinery Co., Ltd. can have three functions: manual cutting, CNC cutting, and plasma air planing. It adopts high-frequency arc ignition technology and the current output ranges from 30A to 130A. When the 100A machine current is 80A, it can meet continuous work all day long, and when the 130A machine current is 110A, it can meet continuous work all day long!

Ionic air gouging can be carried out using other mixed gases such as air, nitrogen, argon/hydrogen, etc. The mixture of argon and hydrogen can provide clean, bright, and smooth grooves on the surface of stainless steel materials, which can increase the removal efficiency of metals without forming inclusions on the metal surface, and the planing speed is also fast. Plasma gouging can completely perform gouging and root cleaning on non-ferrous metals such as stainless steel, and it is easier to achieve automation after root cleaning than carbon arc gouging. The use of plasma arc cutting machine for stainless steel planing avoids the problem of carburizing of steel body caused by conventional carbon arc gas planing. After root cleaning, the surface does not need to be polished and can be directly welded, which can significantly improve work efficiency and welding quality.
