• Before spot welding, make a trial weld using the
same material as the body panel to check the
weld strength.
Checking Weld Strength
• Installation locations of the engine, chassis, and
seat belts are designated as important safety
locations for weld strength. Check weld strength
by driving a chisel between the panels at every
fourth or fifth weld spot, and every tenth regular
weld location.
• Drive the chisel between the panels according to
the number of panels as shown below.
• To determine weld strength, drive the chisel
between the panel and check whether the panels
come apart. If the panels come apart, make
another weld near the original weld.
• Restore the shape of the checked area.
