What material is the excavator cylinder and what welding wire is needed to weld the excavator cylinder?

Excavator cylinders are generally forged steel or cast steel with high carbon content. When welding, alloy steel welding wire WEWELDING600tig can be used as backing weld, and the upper surface is covered with WEWELDING600 coated covered electrode, which saves preheating and heat preservation.

Application of WEWELDING600 special alloy steel covered electrode

Suitable for welding tools and dies, high-speed tool steel, hot working tool steel, manganese steel, cast steel, T- 1 steel, shock-resistant steel, vanadium-molybdenum steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, unknown steel and various types of steel. For example, it is used for the removal of high-pressure valves, broken bolts, shaft reconstruction, etc. And the effect is very ideal.
