Galvanic Corrosion Inodzivirirwa Sei??
Galvanic isolation ndeyekuzvarwa. The aluminum-steel bond is a continuous metallurgical joint. There is no gap. No moisture penetration. The edge of the panel is the only area needing protection. Weld procedures include a seal weld at the edge. Uyezve, the aluminum surface can be anodized. Steel side can be painted. No special coatings needed for the interface itself.
What Are the Welding and Fabrication Considerations?
Shipyards must follow specific procedures. Weld only to the steel side or the aluminum side, not across the interface. For steel-to-steel welding, standard steel electrodes are used. For aluminum-to-aluminum welding, standard aluminum filler (e.g., ER5356) inoshandiswa. Zvakakosha: remove the aluminum layer from the weld zone if welding to the steel side. This is done by grinding or machining a groove. Then weld the steel. After welding, the aluminum side is protected. Hapana preheat yakakosha inodiwa. AWS D1.1 uye D1.2 inoshanda.
