Embodiment Construction

[0010] The present invention includes a power supply device 1, which is connected with a coil 5 in a supporting frame 6 through a wire 7;

[0011] A silicon steel sheet 10 can be arranged in the coil 5; thereby increasing the strength of the magnetic field.

[0012] The coil 5 is placed on the outer surface of the plasma arc welding torch 8 connected to the cable 9 and fixed on the corresponding feeding device with the support frame 6. The whole of the coil 5 of the present invention is placed directly above the workpiece 4, and two adjustments are made as required. the distance between them. When in use, first connect the power supply device 1 of the welding machine equipment, start the welding machine, then turn on the switch 2 of the magnetic field power supply device 1 to energize the coil 5 and generate a corresponding magnetic field, and then let the plasma arc welding torch 8 contact the workpiece 4 to start the arc 3. Then the workpiece 4 is welded by moving the plasm...

Abstract

The invention discloses a production method for improving the wear resistance of plasma arc surfacing, which relates to the improvement of a welding processing method of plasma arc surfacing. Based on common surfacing alloy, the invention changes the crystallization process of a surfacing layer by applied magnetic field, and controls the distribution pattern of hard phase in the surfacing layer, thus improving the wear resistance of the surfacing layer. The invention comprises power supply equipment, which is characterized in that the power supply equipment is connected with coils arranged in a braced frame by wires. A plasma welding torch can weld under the action of magnetic lines of force of the coils.

Description

Technical field: [0001] The invention relates to an improvement of a plasma arc surfacing welding processing method. Background technique: [0002] Wear is one of the three main failure modes of materials, and the economic loss it causes is very huge. In a report submitted to the U.S. Congress by the U.S. National Materials Policy Committee, it was pointed out that the loss caused by friction and wear caused the U.S. economy to pay a huge sum of 100 billion U.S. dollars every year, and the material part of this loss was about 20 billion U.S. dollars; In a survey of the former Federal Republic of Germany in 1996, it was pointed out that the loss caused by friction and wear was estimated to be 38.7 billion marks; 1.1%. Our country has conducted a comprehensive investigation and analysis on the economic loss caused by friction and wear, and pointed out that this loss accounts for at least 1.8% of the gross national product every year. The patent applied by Matsui Integer of ...
