Welding and finishing of the sheet metal

WELDING AND FINISHING OF THE SHEET METAL

a. All welding should be carried out in strict accordance with the indications in "WELDING PRECAUTIONS".
Tools required:

• Spot welder
• MIG welder
• Oxyacetylene torch.

b. After welding remove the clamps used to hold the edges in place and remove the dents which may have been caused.

c. Sand the welds with a sander.
Tools required:

• Pneumatic sander
• Disk sander
• Grinding machine with milling cutter.

WARNING:

• When using the sander care should be taken to avoid excessively reducing the thickness of the metal sheet as this may adversely affect welding strength.
• Remove metal dust from the surfaces that have been smoothed and from the surrounding areas.
• Metal dust may cause corrosion.

PROTECTION

a. Apply a rust inhibitor to the components subject to MIG welding and oxyacetylene torch.

b. Apply the specified sealant to the joints in the metal.

c. Carry out the paint, wax and foam treat procedures (see specific paragraph).
