A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]
1. Gas plasma, 2. Nozzle protection, 3. Shield Gas, 4. Electrode, 5. Nozzle constriction, 6. Electric arc. Plasma arc welding (PAW) is an arc welding process similar to gas tungsten arc welding (GTAW). The electric arc is formed between an electrode (which is usually but not always made of sintered tungsten) and the workpiece.
CNC plasma cutting Plasma cutting performed by an industrial robot. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
The flow rate DOES change, as the plasma reacts to the electric field in the torch and on the workpiece. - Toastydeath 04:24, 5 December 2006 (UTC) To give an idea of the flow rate while plasma cutting: The flow of a Hypertherm plasma 260A for mild steel uses 42 l/min for the plasma gas (O2) and 104 l/min for the shield gas (air).
Slag forms from the use of a flux, which is why this type of defect usually occurs in welding processes that use such flux, such as shielded metal arc welding, flux-cored arc welding, and submerged arc welding; but it can also occur in gas metal arc welding. This defect usually occurs in welds that require multiple passes when there is poor ...
A submerged arc welder used for training Close-up view of the control panel A schematic of submerged arc welding Pieces of slag from submerged arc welding exhibiting glassy surface due to silica (SiO 2). Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.
The F-Arc is born out of Voltage and initiates around V (F-Arc_init_min), and the F-Arc plasma is maintained at or above the minimum-arc-current of I (arc_plasma_min). [8] While arcing occurs during both the BREAK and MAKE transitions, the break arc is typically more energetic and thus more destructive. [8] [9] [10] Potential MAKE F-Arc plasma ...
Air carbon arc cutting, also referred to as metal arc gouging, and previously as air arc cutting, [1] 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.
