Cracks in cast iron pipes must be welded at one time. Welding with stainless steel is taboo and easy to explode. If the crack is not critical, use ordinary 506 to weld by hot welding process, but it is not safe. If it's safe, we should weld it with WEWELDING777 special cast iron by cold welding, but there are too many fakes in WEWELDING777 in covered electrode, so we can consult WIODING welding in advance.
In the welding process, three problems are well controlled: carbon control, stress relief and structural adjustment, and imported welding materials such as WEWELDING777 are selected for welding, which has very good crack resistance. In addition, the structure can be repaired by sewing technology to increase the stability of welding effect. Please consult the welding technician of Viodine for details. ?
