This welding process is affected by equipment and current and voltage matching. Generally, the welding strength of double rods is higher than that of a single rod. This welding process is also related to the concave and convex of the flat steel material. A large width of the flat steel may affect the welding strength and make the strength inconsistent. ; The defect in this process is false welding and false welding, which can easily cause the crossbar to peel off.
Due to the rated capacity of the equipment, the welding process cannot produce heavy-duty steel gratings with larger cross-sections. Equipment with a rated capacity of less than 800KVA for this welding process can generally only produce flat steel gratings with a thickness of less than 4mm, while equipment with 1250KVA can generally produce flat steel gratings with a thickness of 5~6mm.
Handmade steel gratings include pressure locking, welding, interlocking and welding-free, etc. Hand-made welded steel gratings are made by first punching holes or notches in the flat steel, and then placing the crossbars into the holes and spot welding. There will be gaps between the crossbars and the flat steel, and each contact point between the crossbars and the flat steel is processed. Welding, if the crossbar is dense, it can also be welded at intervals.
