1. The plasma arc energy is concentrated, the arc temperature is high, the heat transfer efficiency is high, the stability is good, the penetration depth is controllable, and the thickness, width and hardness of the surfacing layer are wide.
1. The plasma arc energy is concentrated, the arc temperature is high, the heat transfer efficiency is high, the stability is good, the penetration depth is controllable, and the thickness, width and hardness of the surfacing layer are wide.
2. The structure of the surfacing layer is dense, the bonding between the surfacing alloy layer and the substrate is high, the metallurgical bonding is presented, the welding defects are few, and the forming is beautiful.
3. A wide range of applicable base materials, the use of powder as a welding material, especially the smooth surfacing of refractory materials, low dilution rate, small changes in material characteristics.
4. Support pulse welding, low heat influence, low dilution rate, high bonding strength, low maintenance cost, good economic benefit, and wider welding range.
5. The electrode is shrunk in the nozzle, which is not easy to be polluted and burned, the electrode has a long service life and few weld defects.
6. The repair technology that supports recycling and reuse is in line with the future development direction of environmental protection, and is the most economical and reasonable treatment technology to improve the service life and performance of the workpiece.
