Nissan Armada 2025-2026 Service and Repair Manual: Precautions when Performing Spot Welding

Nissan Armada 2025-2026 Service and Repair Manual / Body Exterior, Doors, Roof & Vehicle Security / Body Repair — Fundamentals / Service Information / Precautions when Performing Spot Welding

(1) SELECTION OF SPOT WELDING MACHINE

Use the direct welding method whenever possible.

(When direct welding cannot be applied, use MAG plug welding.)

(2) APPLICATION OF ELECTRODE TIPS

Apply electrodes at right angles to the panel. If they are not applied properly, the current density will be low, resulting in poor welding strength.

(3) NUMBER OF SPOT WELDING POINTS

Generally, the capacity of repair shop spot welding machines is smaller than that of factory welding machines. Accordingly, the number of points of spot welding should be increased by 20% - 30% over the spot weld number indicated in the Body Repair Manual.

(4) WELDING CORNERS

Do not weld the curved corner. Welding this portion results in stress concentration, which leads to cracks.

Examples:

Upper corner of front and center pillars
Front upper portion of rear fender
Corner portion of front and rear windows

(5) MINIMUM WELDING PITCH

The minimum welding pitch varies with the thickness of panels to be welded. In general, observe the values in the following table.

NOTE:

The excessively small pitch allows the current to flow through surrounding portions, resulting in poor welding strength.

Avoid welding over previously welded areas.

As spot welded portion will become harder and thinner, the different portion should be welded as possible.

	Old Spot Locations
	New Spot Locations

(6) MINIMUM LAP OF PANELS

Observe the following values for the lap distance of panels. Too short of a lap distance results in reduced strength and also in a strained panel.

NOTE:

Be sure to spot weld at the center of the overlapped portion.

(7) SPOTTING SEQUENCE

Do not spot weld continuously in one direction only. This causes weak welding due to the shunt effect of the current. If the welding tips become red-hot, stop welding and cool the tips.

Condition of the Panel

Before beginning, thoroughly check the panel and make any necessary corrections. (1) CLEARANCE BETWEEN WELDING SURFACES Gaps between the surfaces to be welded cause poor current flow. Even if welding ...

Inspection of Welded Portion

Spot welded portions can be checked by the destructive inspections explained below. They can be easily adopted when welding. Before and after welding, you should perform these destructive inspections ...
