Who invented carbon arc gouging?
Arcair
Arcair and SLICE products are synonymous with the air-carbon arc gouging and exothermic cutting processes. Arcair invented arc gouging in 1949, and we’ve been the leading name in metal removal and cutting ever since.
What is the main application of arc air gouging?
The main goal of air arc gouging is to remove defective or old welds to repair or dismantle equipment. Unlike oxy-fuel cutting, air arc gouging avoids the need for oxidation of the metal to cut. The rate of metal removal depends on the efficiency of air jet in removing molten metal and the melting rate.
Can you air arc aluminum?
The air carbon arc process is inexpensive and efficient on all suitable metals. It is used for gouging and cutting magnesium, iron, copper, aluminum, and stainless and carbon steels.
Can aluminum be arc gouged?
It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet. This process is useful for cutting a variety of materials, but it is most often used for cutting and gouging aluminum, copper, iron, magnesium, and carbon and stainless steel.
Can you air arc stainless steel?
The air carbon-arc process does not require oxidation to maintain the cut, so it can gouge or cut metals that the OFC process cannot. Most common metals (e.g., carbon steel, stainless steel, many copper alloys and cast irons) can be cut using the air carbon-arc process.
What is arc gouging?
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. It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet.
How does air arc gouging work?
Air carbon arc gouging works as follows. An electric arc is generated between the tip of a carbon electrode and the workpiece. The metal becomes molten and a high velocity air jet streams down the electrode to blow it away, thus leaving a clean groove.
What is oxy arc cutting?
“Oxygen-arc cutting is an oxygen cutting process in which metal is severed by means of the chemical reaction of oxygen with the base metal at elevated temperatures,” explains IMCA’s Technical Director, Jane Bugler. The metal oxidises and is blown away.
Can you air arc stainless?
Can you arc gouge cast iron?
Application. 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 much air does an air arc need?
A minimum extension of 2″ should be used to prevent damage to the torch parts. Normal compressed air pressures for CAC-A range between 80 psi and 100 psi at the torch; higher pressures may be used, but they don’t remove metal more efficiently. Use 60 psi (413.7 kPa) with the light-duty manual torch.
How to use gouging rods?
Insert the rods into the handles. Drill for a locking screw on each handle. This screw fixes the rods so they cannot shift or rotate from your setting of their angle. Now place the spring into the countersink holes on the inner surfaces of the handles.
What is gouging in welding?
Arc Gouging. The main advantage of manual metal arc (MMA) gouging is that the same power source can be used for welding, gouging, or cutting, simply by changing the type of electrode. As in conventional MMA welding , the arc is formed between the tip of the electrode and the workpiece.
What is air arc welding?
Typical operating data for air carbon arc gouging: Gouging is commenced by striking the electrode tip on to the workpiece surface to initiate the arc. Unlike manual metal arc (MMA) welding the electrode tip is not withdrawn to establish arc length. Molten metal directly under the electrode tip (arc) is immediately blown away by the air stream.
What is an arc welder?
An arc welder is a device used to join two or more pieces of steel together. By using electric current, the arc welder generates enough heat to actually melt the pieces of steel.
