The preparation of EN10083-3 alloy steel 38MnB5 plate 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 EN10083-3 alloy steel 38MnB5 plate centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
