What is carbon arc gouging used for?

Asked by: Rodney Murphy

Carbon arc gouging, commonly referred to as air arc gouging, is often chosen for material removal because it’s a portable process that can quickly remove a lot of material. Sometimes gouging is necessary to complete a specific type of weld for the weld joint design.

What is carbon arc welding used for?

The purpose of arc welding is to form a bond between separate metals. In carbon-arc welding a carbon electrode is used to produce an electric arc between the electrode and the materials being bonded. This arc produces temperatures in excess of 3,000 °C.

What is carbon gouging?

Carbon-arc gouging is a melting operation, where metal is removed from the surface by the arc pressure or force. Direct current (DC) is used and the electrode is graphite coated with a layer of copper to assist conductivity. Most materials may be gouged by the process, but the cut is usually wide and ragged.

What do you need to arc gouge?

So what does it take to carbon arc gouge what equipment is involved first of all there's a torch this is a k4000 carbon arc torch. It requires an air source it requires carbon arc electrodes.

How does air arc gouging work?

Air carbon arc cutting, also referred to as metal arc gouging, and previously as air arc cutting, is an arc cutting process where metal is cut and melted by the heat of a carbon arc. Molten metal is then removed by a blast of air.

What is the purpose of gouging?

A: Gouging is necessary for many tasks related to welding when the operator is trying to remove material to get to clean metal. The most obvious use of gouging is to remove large amounts of metal or welds that need to be repaired.

Can you arc gouge without air?

having to invest big bucks in an air-arc cutting equipment (or worrying about starting fires when using it out doors). ZENA NO-Gas arc cutting/gouging rods let you gouge, bevel, and cut metal without needing a 300+ Amp air-arc gouging/cutting rig or an acetylene cutting torch and bulky gas bottles.

How many amps do you need to carbon arc?

Air Carbon Arc Gouging Procedure Schedule

Can you carbon arc gouge stainless steel?

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.

Can you carbon arc gouge cast iron?

As air carbon arc gouging does not rely on oxidation it can be applied to a wide range of metals. DC (electrode positive) is normally preferred for steel and stainless steel but AC is more effective for cast iron, copper and nickel alloys.

How many amps do you need to arc gouge?

Gouging Electrodes

What type of power source is needed for air carbon arc gouging?

three-phase welding power source

However, any three-phase welding power source of sufficient capacity may be used for air carbon arc gouging. The arc voltage used in air carbon arc gouging and cutting ranges from a low of 35 to a high of 56 volts; thus the open-circuit voltage should be at least 60 volts.
