Inspection and Repair of Bonded Joints

Inspection and Repair Of Bonded Joints

Particular attention should be given to these joints when diagnosing collision damage and performing body repairs.

Note the following points: Do not use a chisel to test the strength of a joint and do not relieve stresses by hammering, as this will destroy the bonded joint.

These areas should be inspected particularly closely when diagnosing collision damage and after performing straightening work.

Perform repair in the following manner: Loose spot weld: Pop rivet at left and right. Loose bonded joint: One pop rivet between 2 spot welds.

Galvanized steel pop rivet 6.4 mm, Hemlok type, manufactured by Avdel or Magnabulb type manufactured by Huck. Hole diameter 6.6 mm.

If the joint is not accessible with pop rivets, it must be repaired with a gas-shielded arc weld seam. In this case, the entire area of the joint must be re-welded, as the heat produced by welding destroys the adhesive in the bonded joint. The gas-shielded arc weld seams should be welded working from the the thinner to the thicker panel. When doing so, the welding fumes must be exhausted.
