Daewoo Tacuma: Body Repair Manual — part 7
3–4 WELDING AND TOOLS
NOTE:
It is difficult to perform spot welding in the following cir-
cumstances.
•
When it is not possible to remove any rust or paint
attached to the welding surfaces.
•
When the tip of the spot welder cannot be inserted
into the welding section.
•
When the welding surfaces can be seen from the
outside and welding will impair the exterior appear-
ance.
In all these cases, it is recommended that the gas weld-
ing method be employed. However, if it is not possible
to perform spot welding because of space restrictions,
plug welding based on the arc welding method may be
performed instead. Here the welding sections must be
close together.
2. GAS WELDING
Gas welding is indispensable for body repair because
of the broad range of its applications from joining the
body panels, cutting the materials that construct the
body and applying heat to reform panels, and also be-
cause it is easy to get hold of the tools.
However, this method requires experience.

welding, avoid operations like this.
3. CARBON DIOXIDE ARC
WELDER(MIG ARC WELDING)
This welding process uses inexpensive carbon dioxide
instead of expensive inert gases as a shielding means.
Consumable metal electrodes are employed. It has a
wide range of applications, including butt welding of thin
plate, fillet welding, plug welding, and MIG spot weld-
ing. In terms of the weld strength, it is also highly stable.
• Welding the bending angle of a flange
• Melting the finger end of a flange
