Mdc-500p is a full digital control inverter MIG-MAG arc welding power supply for high-end welding field, with minimally invasive cold welding (MDC), pulse, DC low fly, space welding, mixed process and other welding processes, can weld more than 0.3mm carbon steel and stainless
Second, welding process introduction
2.1 Welding process -MDC
The revolutionary innovation of the MDC welding process is the real-time control of the size and direction of the wire feed speed, through the dual servo motor to achieve the wire cycle feed-in and withdrawal, using mechanical forces to promote the stable transition of the droplet at lower currents and temperatures. Dual servo motor wire feeding system with high performance arc welding power supply host, cooperate to output welding wire motion curve and current and voltage waveform, and finally achieve accurate control of arc shape, molten pool shape and molten drop transition. It can weld stainless steel, carbon steel, high-strength steel, nickel-based alloy, copper, aluminum alloy and other metal materials.
The advantages of MDC welding process compared with traditional DC, pulse welding process are
The average welding current is low, the heat input is greatly reduced, and the welding speed is fast
The liquid bridge is pulled off by mechanical force instead of current explosion, and the spatter is greatly reduced, and the spatter-free arc transition period is short, the maximum welding frequency is 200Hz, and the high-speed welding can reach 4m/min
The temperature of molten pool is low, and the gap bridging ability is stronger
