適用范圍：This European Standard gives general recommendations for welding of clad steels by means of appropriate arc welding processes and electroslag strip cladding. It is generally applicable to all clad steels and is appropriate regardless of the type of fabrication involved, although the application standard may have additional requirements. Non-ferrous claddings, such as titanium, tantalum, zirconium and their alloys are not covered by this standard. Examples for joint preparation are given in EN ISO 9692-4. This standard covers welding of cladding deposits as well as welding of the transition zone(s), when existing, between parent metal and cladding. These transition zones are metal combinations of non-alloyed ferrous parent metal with high alloyed stainless steels, nickel alloys or other non-ferrous metals. The mechanical and physical design of the joints is not covered by this standard. Methods of testing and acceptance levels are not included because they depend on the service conditions of the fabrication. These details should be obtained from the design specification. The corrosion resistance of the cladding depends on many factors and is not a part of this standard. For general guidelines see EN 1011-1.
