Project info
Preheating is a very important step in cast steel welding.
Our customer delivered these giant cast steel skim pans used in the aluminum smelting Industry, they had cracks in between the drainage holes.
After hours of grinding the cracks into X shapes, we were ready to pre-heat the parts.
When the parts arrived at the right temperature, we were able to weld them layer by layer back to their original shape.
After a gradual cooldown of the parts, there were no cracks in sight, and the cast iron skim pans were ready to ship back to our customer
