Welding methods:
l To guarantee the welding quality of cladding, smaller diameter welding rod should be applied by multi-layer of welding seam, while the seam height should be kept minimum.
l Welding on cladding, the flux and other surface attachment must be removed, the interlayer temperature shall be controlled under 60 Celsius degree.
l More notice shall be taken on welding start and stop. The end of welding should fill up the welding pit, multi-layer welding seams should be staggered.
l While welding the first layer on bottom plate, special attention should be taken to avoid low alloy metal settled on cladding. 1.5-2.5mm of transition layer melting metal must be paved along the plate, while surpassing the interface by 0.5-1.5mm between stainless steel and carbon steel.
l The first welding seam of transition layer should adipt smaller parameters, anti-polarity, straight and multi-welding seams to reduce the dilution to cladding.
