What is Arc Gouging in Welding?
Arc gouging is a welding process that uses an electric arc to remove material from a workpiece. Arc gouging can be performed with either a handheld torch or a machine-mounted gouging torch.
What is the purpose of arc gouging? What is it used for?
The main purpose of arc gouging is to remove metal from a workpiece. It can be used to create bevels or grooves in metal, but can also be used to remove weld bead defects or to prepare a surface for welding.
What are the types of gouging?
There are 2 main types of arc gouging:
- Air carbon-arc gouging uses a carbon electrode to create an arc between the electrode and the workpiece. The heat of the arc melts the metal, and the pressure of the carbon electrode blows away the molten metal.
- Plasma arc gouging uses a plasma torch to create an arc between the electrode and the workpiece. The heat of the arc melts the metal, and the plasma gas blows away the molten metal.
What are the benefits of arc gouging?
The main benefit of arc gouging is that it can remove metal quickly and efficiently. It also produces less heat than other methods of metal removal, such as grinding or cutting.
What are the disadvantages of arc gouging?
The main disadvantage of arc gouging is that it can be dangerous. The arc can cause burns and the molten metal can cause injuries.
What is gouging in fabrication?
Gouging in fabrication is the process of removing metal from a workpiece using an electric arc. This can be done with either a handheld torch or a machine-mounted gouging torch.
What is arc gouging polarity?
There are 2 types of arc gouging polarity:
- Reverse polarity – the electrode is connected to the positive terminal of the power source, and the workpiece is connected to the negative terminal.
- Direct polarity – the electrode is connected to the negative terminal of the power source, and the workpiece is connected to the positive terminal.
