Galvanic Corrosion and Housekeeping

Avoidance of galvanic corrosion is an important issue to be considered in the repair of aluminium bodied vehicles. Galvanic corrosion is the " cross-contamination " of dissimilar metals, in this case aluminium and steel.

Precautions to prevent the contamination of exposed bare aluminium surfaces should be taken.

Good housekeeping / cleanliness should be adopted throughout repairs and especially prior to welding, pre-treatment and adhesive bonding.

The repair environment requires control and protection from dust and debris from conventional steel body repairs.

All equipment used must be clearly identified and used solely on aluminium.

Tools should be kept clean and in good order.

Steel fastenings are coated to prevent galvanic corrosion.

Fastenings should be examined during repairs and where damaged or suspect must be renewed
