S355K2G2W steel , one grade of corrosion resisted steel, also called weathering steel, is mainly applied to manufacturing containers, railway vehicles,oil derrick,sea port structures,oil extraction platform, and vessel structures of petrochemical processing equipments. if you want to know more information about S355K2G2W welding procedure and S355K2G2W applications , please see following:
For its name,S355K2G2W means, S-steel, 355---min yield strength. K2--impact at -20°C, G2--welded property, W--- weathering steel. It is a weathering steel, with yield strength 315-355 MPa and tensile strength 490-680 MPa. Besides,as the standard requirement, S355K2G2W should be impacted under -20°C and the energy is min 40J. It is S355K2G2W important characteristic. Compared with other weathering steel grade,its main characteristic is, it owns higher impact energy.
G2 has shown that S355K2G2W enjoys good welded property. Same with other weathering steel, S355K2G2W is also easily welded using all common procedures used for mild steel plates (spot,TIG, MIG, MAG, electrode etc.). It is however advisable to avoid tempering in the heated zone and therefore to limit the ratio of linear energy to the thickness.
S355K2G2W can be welded both manually and mechanically, provided the general rules of welding practices are observed. A prerequisite for obtaining identical mechanical properties in the weld and in the base material is the application of suitable welding consumables and the choice of appropraite welding conditions. To consider are EN 10025-5 - Technical delivery conditions for structural steels with improved atmospheric corrosion resistance.
For unprotected use care must be taken that the welded joint is also weather resistant. This is possible by using welding consumables matching the base material.If due to design or building specification stress relieving is required, it should be performed in the range temperature from about 530°C to 580°C.
