What type of welding wire should be used to weld cast iron parts with carbon dioxide gas shielded welding?
Carbon dioxide gas shielded welding non welding cast iron.Carbon dioxide welding wire models.JY50-6 with GB/T8110-1995 (ER50-6) CO2 gas shielded arc welding is suitable for low carbon steel and low alloy steel in AWS ER70S-6.JY50-6 welding, especially suitable for vehicles, containers, engineering machinery, pressure vessel welding jie. JY-308 with GB/ T17854-1999 (H0Cr21Ni10), AWS ER308, JIS Y308. is equivalent to JY-308 for tungsten argon arc welding of stainless steel wire for welding of Cr18Ni8 stainless steel, chemical industry, petroleum equipment, little spatter, weld appearance. JY49-1 (H08Mn2SiA) conforms to GB/T8110-1995 (ER49-1) JY49-1 welding wire, suitable for low carbon steel and low alloy steel CO2 welding, such as construction machinery, bridges, vehicles, pressure vessels and other welding. JY44-8 (I) conforms to TB/T2374-1999 (H08MnSiCuCrNi I), and is suitable for weathering steel welding in railway rolling stock and automobile manufacturing industry.Welding wire specification: 1.0mm Cu. 1.2mm 1.6mm welding wire type "I" means carbon dioxide welding wire model of "8" means that the welding wire containsCarbon dioxide shielded welding wire, welding H08MnSiA welding wire for low carbon steel,H08Mn2S welding wire for welding low alloy steel,The utility model has the advantages of low cost, high production efficiency, good operation, good welding quality, etc.;Choose the appropriate welding wire, mainly to prevent spatter and affect quality, the landlord can choose as neededThe remaining flux cored wire is classified as EF-1 DC, single pass weldingEF-2 DC, single pass weldingEF-3: direct current, single pass soldering, except for core components and EF-1
Cast iron with high carbon content and impurity, and has low plasticity, poor weldability, sensitive to the cooling rate after welding characteristics, prone to white tissue and cracks, should pay attention to the process, preheating before welding, after welding heat, eliminate stress, otherwise easy to crackGray iron:Z208, Z248: grey cast iron electrode, semi thermal welding, thermal welding, welding without preheat, defects of large stiffness parts easy to crackZ308: pure nickel cast iron electrode, arc welding, good crack resistanceZ508: copper nickel cast iron electrode, arc welding, weld shrinkage, easy to crack, but hammer effect, can prevent crackingZ112, Z100: Iron and steel core cast iron electrode, welding, easy to produce hot crack and peelingZ116, Z117: high vanadium electrode for high strength gray cast iron, welding, better crack resistanceZ607, Z612: copper steel welding rod, welding, good crack resistance and multilayer welding produce blowholeSpheroidal graphite cast iron:Z258: ductile iron electrode, preheating weldingZ238SnCu: nodular cast iron welding rod, preheating welding, non preheating welding, heat treatment after weldingZ238F: ductile iron electrode, usually without preheating welding, suitable for lower strength nodular cast ironZ238: ductile iron electrode, usually without preheating welding, good crack resistanceZ408, Z438: nickel cast iron electrode, arc welding, good crack resistanceZ408A: copper nickel cast iron electrode, arc welding, good crack resistanceVermicular graphite cast iron:Z288: vermicular cast iron welding, arc welding, better crack resistanceZ358: pure nickel vermicular cast iron welding, arc welding, good crack resistanceWhite cast iron:BT-1: white cast iron bottom electrode, arc cold welding, good crack resistance, shall be equipped with a special processBT-2: white iron layer electrode, arc welding, good crack resistance, shall be equipped with a special process
