WELDING
BASE OF BODY REPAIR
9-3
PROCEDURE
There are three basic stages in electric resistance spot weld-
ing.
1. Initial pressure application stage
This stage precedes the current application. Applying
pressure to the steel panels through the electrode tips
ensures a uniform contact resistance and a smoother
current flow.
2. Current application stage
While an ample amount of pressure is being applied, the
current is sent through the electrode tips. The contact
resistance causes the contact surfaces of the steel panels to
heat up and fuse together.
3. Holding stage
When the current application is finished and a nugget (a
solidified piece of molten metal) forms at the weld, the
pressure application is continued in order to strengthen the
weld. This is the most important stage of electric resistance
spot welding in ensuring the strength of the weld.
