Gas-arc welding with a consumable electrode (Freelander 2)

Equipment setup and selection of welding parameters:

Any connections made during the manufacture of the vehicle using MIG/MAG technology must be connected by welding using the same technology during the repair process. In addition, individual contact welding points must be replaced with electric rivets during the repair process.
Replacing contact welding points with electric rivets (see above) is done when access is difficult or equipment for contact welding is not available at thicknesses over 3 mm. However, this leads to an increase in the time required to perform the operation and, accordingly, to higher requirements for corrosion protection.
Welding repairs can only be performed properly if the equipment and all welding parameters are set up correctly.

Equipment:

Adjust the equipment according to the manufacturer's instructions.
The hoses must not be twisted.
The holder must be free of electrode wire particles.
Gas nozzles must not be clogged with slag and scale.
Monitor the quality of welding electrodes and gas consumption.

Body:

Make sure the surfaces to be joined are of good quality.
Prepare the exposed metal surface at the joint.
Ensure correct gaps (formation of seam roots).

Notes on methodology/technology:

NOTE: The increased heat generated during MIG welding will destroy the weld primer/zinc layer over a larger area than with resistance spot welding, resulting in increased labor costs when applying subsequent anti-corrosion coating.

NOTE: To ensure that the weld is not just a surface bond, a test weld should always be performed.

Connect the ground cable near the welding area (make sure the contact is good).

When using electric rivets, to ensure high-quality welding, you need to start welding from the bottom panel.
