      *a Ultra High Strength Steel Welding Point - -

        Follow the welding conditions below when welding ultra high strength steel to assure sufficient weld strength. (When repairing this model)

      • When welding 2 panels together including 980 MPa ultra high strength steel.

        *a: Plug weld Plug diameter 10 mm (0.39 in.)
        Wire type AWS A5.18 ER70S-3
        Shield gas Metal active gas

        Note

        Be sure to use Metal active gas (Ar 80% + CO220%) as the shield gas when plug welding.Sufficient weld strength cannot be assured when using 100% CO2shield gas.

    2. After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
