Welding Notes
• For the number of weld points, welding should be
performed in accordance with the following
reference standards.
Spot Welding Notes
• The shape of the spot welder tip is D=(2×t)+3. If
the upper panel thickness is different from that of
the under panel, adjust to the thinner one.
• Because the weld strength is affected by the
shape of the spot welder tip, the optimum
condition of the tip should always be maintained.
• Spot welds should be made at points other than
the originally welded points.
• Before spot welding, make a trial weld using the
same material as the body panel to check the
weld strength.
