The next method, oxyfuel gouging, involves using fuel gas to heat steel to its ignition temperature. Once the metal is nice and hot, it is rapidly combusted, then blown away by a jet of oxygen gas. Oxyfuel is quieter and faster than mechanical gouging, but the process is often hard to control, even if you have years and years of experience.
How plasma gouging works. 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.
Jul 25, 2018· Air carbon arc gouging is a process of removing metal by means of heat generated from a carbon arc. The process uses a carbon/graphite electrode, compressed air and a standard power source. The intense electric arc used between the tip of a carbon electrode and a metal work piece cuts and melts the work piece.
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.
Common methods of gouging are mechanical techniques such as grinding, hand milling, routing, and chipping; oxy-fuel gouging, which can be used only on carbon steels; and air carbon-arc gouging. The plasma cutting process was invented in 1954 at the Tonawanda Laboratory of the Linde Division of …

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.
3 June 2017 - Gouging processes This process is the best alternative to traditional gouging more particularly when precision 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 Plasma cutting it enables the removal of metal
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.It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet.
4. Air Carbon Arc Gouging and Cutting Process. 4.1 Air carbon arc cutting is a thermal cutting process where the removal or severing of metal is done by melting with the heat of an arc between an electrode and the workpiece and blowing the molten material away with an air stream.
Dec 11, 2018· The process of air carbon-arc gouging is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air streams down the electrode to blow it away and thus leaves a clean groove. It is a simply process to apply, has a high metal removal rate and gouge profile can be closely controlled.
In the process, the air must lift the molten metal clear of the arc before the metal solidifies. 1.02 HISTORY Air carbon-arc gouging began in the 1940s, evolving from the existing carbon-arc cutting process. Myron Stepath, a welding engineer, developed air carbon-arc gouging to remove several hundred feet of flat, cracked, stainless steel weld.
Sep 07, 2019· Back gouging is a process of cutting a groove in the back side of a joint that has been welded. Back gouging can ensure joint fusion at the root and remove discontinuities of the root pass. This process can also remove the root pass metal if the properties of the metal are not desirable to the finished weld.
Multi-process welders perform stick, TIG, MIG, flux-cored, submerged arc, and arc gouging welding processes. Great choice for manufacturing, construction, fabrication, and heavy duty shop environments. Portable inverters are lightweight and reduce energy demand.

4. Air Carbon Arc Gouging and Cutting Process. 4.1 Air carbon arc cutting is a thermal cutting process where the removal or severing of metal is done by melting with the heat of an arc between an electrode and the workpiece and blowing the molten material away with an air stream.
A high grade, all purpose copperclad pointed gouging electrode. Its controlled copper coating improves electrical conductivity (for more efficient, cooler operation) and helps maintain electrode diameter at …
Nov 25, 2014· In most metal fabrication shops, traditional air carbon-arc gouging (ArcAir™) has proven to be a good process to work in welding applications, but it has its own disadvantages compared to plasma-arc gouging.

Plasma Arc Gouging. With practice, an operator can achieve a smooth, clean, consistent groove with a plasma gouging arc. This process is relatively quiet and smoke-free. It can be used on mild steel, stainless steel, aluminum, and almost any ferrous or nonferrous alloy. Different gases can help optimize gouge quality and surface conditions.
