Galvanizing is an economical and effective rust prevention method that is often adopted, and about half of the world's zinc production is used in this process.

Then, the two side covers 404 are manually toggled so that the two side covers 404 completely buckle the two sides of the galvanized sheet. At this time, the cross baffle 405 automatically buckles the side of the galvanized sheet, so that the welding joints of the galvanized sheet are completely buckled into the heating box 402. Then, the electric air valve on the heating box 402 is opened. At the same time, the heating box 402 heats its interior to realize the welding preheating of galvanized sheets of different widths; When welding the docking joints of the two galvanized sheets, the electric plate door 403 is opened. Then, the upper and lower welding machines 408 weld the upper and lower sides of the galvanized sheet in the heating box 402 at the same time. At this time, the lead screw slider group III 407 works, driving the corresponding welding machines 408 to weld while moving, realizing the intelligent welding of the galvanized sheet, effectively improving the welding efficiency and saving manpower at the same time.
