Advantages of Electrofusion Welding:
Electrofusion welding (EFW, Electrofusion Welding) is a welding process used for the production of tubes made of specialty metal materials, especially stainless steel and alloy steel tubes. This method focuses on heating the material by using a high-frequency current to melt the material.
High quality welded joints: Electrofusion welding provides clean, continuous and uniform welds, improving weld quality and structural strength.
Wide range of applications: Suitable for welding a wide range of metal materials, including stainless steel, alloy steel and other difficult-to-weld materials.
High degree of automation: The electrofusion welding process can be highly automated, resulting in increased productivity and repeatability.
Small heat-affected zone: Since the heat is concentrated in the welding area, the heat-affected zone is small, reducing the loss of material properties.
Environmentally friendly: The electrofusion welding process produces less fumes and harmful gases than conventional welding methods, making it friendlier to the operator and the environment.
