Comparison with other similar manufacturers' products:
At present, most of the similar products on the market use two argon arc welding machines as the power source for surfacing welding, rather than the professional plasma power source. There are the following drawbacks:
1. Because the arc pressure of the argon welding machine is low, it is difficult to guarantee the smoothness of the arc starting of the dimensional arc (non-transferred arc). The stretching distance of the main arc is short, and the limitation of the welding torch is large.
2. The dimensional arc current is large, the nozzle of the welding gun is easy to burn, and energy is wasted at the same time
The patented powder feeder is a new type of powder feeder independently developed by our company. It overcomes many shortcomings of the previous products. The powder feed is more accurate, the powder feed volume adjustment range is wide, and it is simple and easy to maintain. DMB-1 welding oscillator is a universal welding auxiliary equipment, suitable for a variety of welding processes, realizes the welding torch swings from side to side along the seam direction, improves the welding seam formation and increases the production efficiency.
Features: PLC digital program control, touch-type man-machine operation interface, menu-style function selection, high reliability, high control accuracy, strong anti-interference ability, stepper motor drive, ball screw, linear guide transmission mode.
Swing parameters: including swing amplitude, swing speed, center * center position, left/center/right position stay time and other parameters.
Equipment configuration: 1) 1 control box, 2) one set of swing linear slide group, 3) one set of connecting cable
Plasma powder surfacing uses plasma arc as the heat source. The high temperature generated by the plasma arc is used to rapidly heat the alloy powder and the surface of the substrate and melt, mix, diffuse, and solidify together. After the plasma beam leaves, it is self-excited and cooled to form a high-performance alloy. Layer, so as to realize the strengthening and hardening of the surface of the part. Because the plasma arc has high arc temperature, high heat transfer rate, good stability, and strong controllability of penetration, it can be The thickness, width and hardness of the welding layer can be adjusted freely within a certain range. After plasma powder surfacing, a fusion interface is formed between the base material and the surfacing material, with high bonding strength; the surfacing layer has a dense structure, good corrosion resistance and wear resistance; the dilution of the base material and the surfacing material is reduced, and the material characteristics change little; The use of powder as a surfacing material can improve the selectivity of alloy design, especially for smooth surfacing of refractory materials, and improve the wear resistance, high temperature resistance and corrosion resistance of the workpiece. Plasma powder surfacing has high productivity, beautiful forming and surfacing process is easy to realize mechanization and automation
