What is gouging plasma cutting?
Plasma gouging – removing metal using a plasma arc – is similar to plasma cutting. A plasma arc between the torch and the workpiece melts the metal, and a gas jet blows away the molten metal. Plasma gouging works on any conductive metal, including mild steel, stainless steel, aluminum, and copper.
What is the advantage of plasma gouging when compared to oxy fuel gouging?
The major advantages of plasma gouging are incredible accuracy and quick speed. While methods like Oxyfuel gouging are also much faster than mechanical gouging, they lack a certain level of precision and quality. Plasma gouging is also fairly quiet and smoke-free.
Why is plasma arc gouging used?
At standoff distances greater than 25mm, arc/gas forces are reduced and this lessens the depth of penetration of the jet. By reducing the torch angle to the workpiece surface, the plasma jet can be encouraged to ‘skate’ along the surface of the workpiece; this produces a shallower and wider groove.
What is plasma arc cutting process?
Plasma arc cutting, also referred to as plasma fusion cutting or plasma cutting, is a fabrication process which employs superheated, ionized gas funneled through a plasma torch to heat, melt and, ultimately, cut electrically conductive material into custom shapes and designs.
What is a possible use for plasma gouging?
Applications. Plasma gouging was developed as a tool for weld removal and weld preparation. Backgouging was used to remove metal from the reverse side of arc-welded joints to eliminate defects and improve strength.
How does arc gouging work?
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 Unlike manual metal arc (MMA) welding the electrode tip is not withdrawn to establish arc length.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.
Does plasma cutting machine needs oxygen?
Plasma cutting is made possible by introducing electricity into compressed air to create an ionized, imbalanced plasma gas. Oxyfuel cutting is where an oxygen fuel gas flame preheats the material to its ignition temperature, then a powerful oxygen jet is directed at the material.
Which is better plasma cutter or oxy acetylene?
Plasma may be precise, but Oxy-Acetylene is far and away the most powerful cutting method. While plasma can cut materials up to a couple of inches, oxy-fuel can cut through materials that are up to two feet thick. Additionally, if you need to work with aluminum or stainless steel, plasma is your only option.
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.
What are the advantages of plasma cutting?
Advantages
- Able to cut all conductive materials.
- Great quality for thickness up to 50 mm.
- Maximum thickness up to 150 mm.
- Comparatively cheap for medium thickness cuts.
- Best way to cut medium thickness stainless steel and aluminium.
- CNC machines are available to provide high precision and repeatability.
What is the difference between plasma cutting and laser cutting?
Laser cutting is a precise thermal cutting process, utilizing a focused beam of light. Plasma cutting, on the other hand, uses a mixture of gases in order to form a cut. With our high definition plasma cutting equipment, we are able to perform bevel cuts on parts as required.
Can you cut bolts with a plasma cutter?
They also can be used to cut nearly anything that is metal, including steel, stainless steel, and aluminum. You can even use them to cut rusty nuts and bolts just like you would use a gas torch, only much faster and with cleaner results. Treat plasma cutting like welding and gas torch cutting, and you will be OK.
