What kind of welding rod is used for No. 55 steel?
No. 55 steel is made of genuine WEWELDING 600 welding rod.Because the 55 steel for high strength steel, treated with surface hardness and high strength, plasticity and toughness but poor machinability of medium, weldability, hardenability, water quenching is the tendency for crack formation, welding crack resistance of the need for a very ideal electrode to WEWELDING 600 welding, ensure tensile strength requirements of crack resistance and use of the process after welding.Characteristics of WEWELDING 600 special alloy steel welding rodWEWELDING 600 is a low heat output, suitable for special nickel chromium alloy steel electrode welded all-round, universal design is extremely wide, the general strength of parent materials with high strength, excellent welding performance, stable arc, beautiful shape of seam, in oil, water and rust conditions can welding effect is excellent, can be welded different steel.Application of WEWELDING 600 special alloy steel welding rodSuitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.Technical parameters of WEWELDING 600 special alloy steel welding rodTensile strength: 125000 psi (862MPa)Yield strength: 90000 psi (620MPa)Elongation: 35%Hardness after welding: HRC23 (work hardening up to HRC47)Power supply: AC and DC dual use, DC DC reverse connection
To choose J506 or J507 welding rod, preheat 150~200 degrees before welding, heat preservation after welding. Or choose the electrode with higher strength grade
No. 55 steel belongs to medium carbon steel and its weldability is poor. It should be preheated before welding. General structure arc welding using E4301, E4303, E4311, E4313, E4320 or J422 welding rod can be. The stress (main body) structure arc welding uses E4315, E4316, E5015, E5016 or J425 welding rod.
