Comparison between medium frequency DC resistance welding controller and AC control
1. When AC current passes through the welding area, it will diverge
due to the surface effect. On the contrary, the medium frequency
welder outputs DC current with very small ripple
The welding area has a "bunching effect" towards the center. It can
concentrate the welding heat and reduce the heat affected zone
around the welding point. This feature is particularly important
for the welding of multilayer plates and thick plates;
2. The AC welding machine adopts the AC chopping mode, so it has
the characteristics of discontinuous current and high current peak,
which causes the AC welding machine to weld
It is easy to produce a lot of spatter during the welding process,
which will damage the surface of the weldment and bring a lot of
work to the manufacturer. The medium frequency DC welding machine
outputs continuous DC current, with stable current and high control
accuracy. In addition, the bunching effect of DC current ensures
that there is little or no spatter during welding.
3. The medium frequency DC controller outputs DC current with very
small ripple, without zero crossing effect, so it has irreplaceable
advantages in light alloy, heat-resistant steel, precision parts,
high-speed seam welding and occasions with high requirements for
welding quality.
