Nissan Armada 2025-2026 Service and Repair Manual: Process of Spot Welding
It takes 3 processes, “pressurization”, “energization”, and “retention”, to complete the spot welding.
(1) PRESSURIZATION
The welding points of overlapped panels are pressurized with the tip (electrode) for close contact.
With the panels contacting closely, the current can run intensively.
(2) ENERGIZATION
With the panels being pressurized, heavy current is applied.
Joule heat is generated at panel mating areas, and the temperature rises sharply.
The panel mating areas are melted and fused together by welding pressure.
(3) RETENTION
Even after the current is turned off, pressure is still applied until the welded point cools down.
The nugget system becomes delicate by pressurization, resulting in better mechanical properties.
Therefore, the retention process must not be omitted.
Mult-functional Type Spot Welder
In addition to the ordinary spot welding function, sheet metal can be pulled with the sliding hammer.
Major functions:
Both sided spot welding
One sided spot welding (Pre tack welding)
Spot hammer we ...
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 ...
