Is it possible to weld pig iron with ordinary welding machine?
The DC welding machine has no frequency, the welding process is stable, the arc is stable, and the spatter is very small. The welding machine has good dynamic characteristics and high welding seam strength. DC reverse polarity (anode - ground, welding connected with the anode + polarity welding).According to cast iron concrete material, choose matching cast iron electrode welding.
AX series arc welding generator, ZX5 SCR (thyristor) DC welding rod, hand arc welding machine, ZX7 inverter welding rod arc welding machine, suitable for welding cast iron material.
There is no ordinary welding machine, the most primitive is the BX series power frequency AC welding hand arc welding machine, this kind of AC welder is not suitable for welding pig iron (cast iron).BX series power frequency AC welding rod arc welding machine is divided into: BX1 moving iron core, BX2 body type, BX3 moving coil core, BX6 tap welder. By the factors of welding power supply (China frequency alternating current frequency is 50HZ), welding arc to burn out per second of repeat 100 times. The arc is re ignited during each quenching process, which causes porosity, slag inclusion, crack and so on, and the weld strength is low. Only suitable for welding low carbon structural steel such as welding Q235.
