Nissan Armada 2025-2026 Service and Repair Manual: MIG Welding Method
(1) PLUG WELDING
MIG plug welding method is used to repair the spot welded portions.
Keep the upper panel and lower panel tightly together. Before welding, contact closely the points to be plug welded.
Observe the welding condition described in the Body Repair Manual.
(a) Welding condition (plug welding)
Basically, the following welding conditions are intended for horizontal welding. Therefore, depending on the welding direction, adjustment may be necessary.
(b) Three-sheet plug welding condition
Consider the total thickness of two upper panels as the upper panel thickness. Using this thickness, apply the two-sheet plug welding conditions to set plug hole diameter, current, and voltage.
(c) Torch movement
Thickness of lower panel
1.4 mm (0.055 in) or less Weld from the plug hole circumference toward the center in a circular motion.
Thickness of lower panel
1.5 mm (0.059 in) or more Weld from the plug hole center toward the circumference in a circular motion.
(d) Backing block
When thin panels are plug welded, a backing block, as shown in the figure, is placed on the underside of the panels, and fixed onto the plug hole side with a clamp.
This is to prevent thin panels from burning through.
For locations where backing strips cannot be applied, be careful not to burn through.
(2) FILLET WELDING
Before welding, contact closely the points to be fillet welded.
Observe the welding conditions and lengths specified in the Body Repair Manual.
Set the welding range for the fillet welding cross section so that it is same as the panel thickness or wider. When the panels have different thicknesses, perform welding according to the welding conditions applicable to the thinner panel.
(3) SLOT WELDING
Before welding, contact closely the points to be slot welded.
Observe the welding conditions specified in the Body Repair Manual.
Welding range is from 10 mm (0.39 in) before the slot to 10 mm (0.39 in) after the slot.
(4) BUTT WELDING
Observe the welding conditions specified in the parts replacement procedure.
Tack welding: Temporarily, but securely weld at approximately 10 mm (0.39 in) intervals.
Remove aluminum oxides and magnesium oxides generated at tack welded points. Not doing so results in a welding malfunction.
Regular welding.
