The preparation of automobile frame steel S355MC galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for automobile frame steel S355MC centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.Capital letter L for the quality with specified minimum values of values of impact energy. automobile frame steel S355MC. The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM..
