Manual Metal Arc Gouging - MMA, welding, gouging, cutting

The gouging process is characterised by the large amount of gas which is generated to eject the molten metal. However, because the arc/gas stream is not as powerful as a gas or a separate air jet, the surface of the gouge is not as smooth as an oxyfuel gouge or air carbon arc gouge.

Caustic Gouging -

The process finally results in high sodium hydroxide concentrations in the boiler water at the tube surface. The concentrated sodium hydroxide dissolves (fluxes) the ... Caustic gouging may also occur in HP evaporators of HRSGs. Figure 7 shows heavy deposits and gouging in a HRSG tube.

What is Gouging? - Definition from Corrosionpedia

Gouging is a type of corrosion that occurs on a metallic surface in which a hole, groove or indentation is created. Gouging happens in boiler tubes because of caustic corrosion that occurs as a result of excessive use of alkalines such as sodium hydroxide (NaOH).

Seabed gouging by ice - Wikipedia

Seabed gouging by ice is a process that occurs when floating ice features (typically icebergs and sea ice ridges) drift into shallower areas and their keel comes into contact with the seabed. As they keep drifting, they produce long, narrow furrows most often called gouges, or scours.

Gouging processes - GYS

3 June 2014 - Gouging processes This process is the best alternative to traditional gouging more particularly when preci-sion and safety are priorities. With a removal capability of up to 8 kg/h, Plasma gouging improves operating conditions by reducing noise and fumes. Using the same process as

Understanding plasma gouging vs carbon arc & air arc gouging

The plasma gouging process removes any amount of material from a workpiece regardless of shape or rate, without actually severing or piercing the material. Just as in plasma cutting, a plasma arc is formed between a negatively charged electrode inside the torch and a positively charged workpiece.

Gouging how-to - Welding Productivity

The air carbon-arc gouging process does not require oxidation to maintain the cut, so it can gouge or cut metals that the oxyfuel process cannot. In fact, most common metals (carbon steel, stainless steel, high-alloy wear plate, copper alloys and cast irons) can be cut using air carbon-arc gouging.
