Definitions
- the field of plasma welding and cutting is a newly developed field, which has superior energy saving effect and safety and environmental protection effect compared with the original gas welding and cutting.
- BACKGROUND OF THE INVENTION In the existing plasma welding technology, plasma arc welding and plasma cutting; plasma flame brazing is also a relatively mature technology that I have just developed. Because the brazing workpiece is complicated and the brazing space is narrow, the plasma flame brazing gun The head volume is small, which results in limited cooling capacity. It can not be used for high current and large fire brazing.
- the air plasma cutting application is widely used. The disadvantages are that the cutting air is too dusty and the working environment is bad. The second is to cut the thick plate. A high current power supply is required, and the cut is not flat.
- the plasma welding torch is composed of a gun body 6, a cathode column 2, a cathode 12, a nozzle 9, an insulating ceramic 7, an insulating rubber 3 between a gun body and a cathode column; and a cooling water in the gun body 6 Channel 5, water inlet 4, water outlet 14 and radial arc inlet 13; arc chamber 8 between nozzle 9 and cathode 12; cathode column 2 with high pressure inlet 1; cathode 12 with high pressure gas passage 11 and inlay
- the ring emits an electronic electrode metal 10.
- the plasma welding torch is adjusted to mix the alcohol-containing flammable gas.
- the arc is stably maintained at the outer edge of the cathode 12 and the inner wall of the nozzle 9, and a plasma arc flame formed under the action of the arc gas is ejected from the nozzle 9; the alcohol-containing compressed air is mixed from the inlet port 1 of the cathode column 2
- the gas passage 11 to the cathode 12 is flushed out of the nozzle 9, and the rapid combustion releases a large amount of heat to meet the needs of the large workpiece brazing; since the arc is on the outer edge of the cathode 12 and the inner wall of the nozzle, the high pressure gas does not break the arc.
- the arc-mixing alcohol-containing flammable gas is adjusted, and the arc is stably maintained on the outer edge of the cathode 12 and the inner wall of the nozzle 9, and the plasma arc flame formed under the action of the arc gas is from the nozzle.
- Such a cutting operation consumes a small amount of air and does not cause a large amount of dust. Since the vent hole of the cathode 12 is small due to preheating, the thick workpiece can be cut with a small current, and the cutting mouth is also neat.
