| description | The invention provides a method for preventing corrosion of a zinc-aluminum-magnesium coated steel plate during welding along with welding, and belongs to the field of welding corrosion prevention. The method comprises the following steps: welding at least two zinc-aluminum-magnesium coated steel plates to form a welding bead; and placing a low-melting-point anti-corrosion material at the weld bead, and melting the low-melting-point anti-corrosion material by using the welding heat source for welding, so that the molten low-melting-point anti-corrosion material is cladded on at least part of the surface of the weld bead to form an anti-corrosion layer. A welding heat source is used for heating a low-melting-point anti-corrosion material, cladding of the surface of a welding bead is achieved under the action of protective gas, and welding of the zinc-aluminum-magnesium coating steel plate and preparation of an anti-corrosion layer on the surface of the welding bead are conducted synchronously.
