After welding no deformation, no undercut, no color change.
We focus on customer service and after sales service so much to make our customers feel convenience during the using of our machine. Hope our professional will help you reduce the lost and saving the cost.

ATOM Cold welding machine is an electro-spark deposition welding machine widely used in Foundry / Plastic industry / Oil industry / Automobile industry etc.
Use cold welding technology can easily repair defects like porosity defects / sand hole defects / shrinkage defects / Crackle with very small heat affected zone and forming metallurgy combination. Suitable for Ductile iron ; Gray iron ; Aluminum ; Copper and Steel. Will save a lot of cost.

Main features compare to normal welding:
> After welding no temperature on the welded surface. So no annealing to the workpiece.
> After welding no deformation no undercut to the workpiece, the welded area hardness is suitable to be re-machined.
> High technology : Use chopped wave soft switch technology , output more accurate.
> High welding intensity : With high single point power output, each point of welding material is combined with the welding substrate , forming metallurgical combination, molten state to the produce very strong combination, minimal chromatic aberration. Easy to operating, any one without professional training can use and no pollution while using.
