Stainless steel, non-ferrous metals and welding with flux http://xhjd2007.c029.com In this section, we provide customers with a stainless steel, copper and alloy flux with flux, nickel and its alloys, alloy surfacing flux. I also development of special steels with flux according to user requirements. Stainless steel flux targeted on the wire, the base metal is not very strong, a flux (CHF601, CHF260, etc.) can be equipped with a variety of stainless steel wire welding of the corresponding chemical composition and mechanical properties of base metal conditions; non-ferrous metals with flux highly targeted, should be fully validated before the selection of welding wire for welding. Surfacing as a welding material surface will naturally be used for a variety of materials, due to the diversity of the base metal being welded, complexity, users should determine on the basis of the argument in the full test flux. Chrome-nickel stainless steel welding by repeated heating easy to carbide precipitation, so that the corrosion resistance and mechanical performance degradation. Applications with a small current, a small line of energy input to prevent overheating and intergranular corrosion, welding thin channel of the short arc welding. Note that the stainless steel resistance is large, causing wear welding may also be larger, and also easy to cause deformation. Poor thermal conductivity of nickel and its alloys, easy to cause coarse grains, help should be used in small current, small energy input method of welding. Nickel can easily be embrittlement sulfur and lead to the formation of thermal cracks, clean up the base metal surface of the oil, rust, paint, dust, moisture and other impurities before it is welded should be strictly; stomatal sensitivity to nickel and its alloys welding, noting that the operation . The thermal conductivity of copper and its alloys, thermal expansion coefficient, low melting point, is easy to produce cracks, pores and slag easily cause, help with a large heat input welding of copper and its alloys should meet the heat loss caused by a fast cooling rate ; positioning solder joints, as well as increased special process to increase the preheat and interpass temperature hammering.
