Welding condition PLUG WELDING To weld ultra high strength steel of tensile strength 980 MPa or more, perform plug welding observing the CAUTION: • To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder. be secured. For this reason, always use fuel mixture for shielding gas of welder to prevent. • When welding hole diameter cannot be satisfied, make multiple holes (smaller diameter) so that the sum of hole areas becomes equal to the area of the specified weld hole. EXAMPLE Chip tip diameter 6 mm Welding pressure 3100 N Welding current 7900 A Weld time 10 cyc (0.20 sec) Panel configuration Combination of a plate of Body sealing : Vehicle front : Drill φ 6 mm (0.24 in) hole for the plug welding hole (ultra high strength steel). : N·m (kg-m, ft-lb) : For spot welding of steel plate of tensile strength 980 MPa, observe the indicated welding conditions.
