Inspection of welded joints attaching the front and rear outriggers on a Triumph Vitesse.

1. Introduction

1.1
A request was received for an examination to be carried out on the subject vehicles welded repair joints.
1.2
The inspection requested, was to determine the fitness for purpose of the joints.

2. Inspection Results

2.1
The repair positions on the outriggers are shown on Plates 01 to 06. All repairs appeared to have been carried out using shielded arc welding.
2.2
The front outriggers had been sleeved onto abutments on the chassis and the joints made by fillet welding where accessible. The static strength of the joints was considered to be adequate on both sides. However, as the dynamic reactions from the anti-roll bar from direct vertical loads and when it acts as a torsion spring will subject the joint to fatigue conditions the quality of the bottom transverse welds could be inadequate.
2.3
The repair methods used on the rear outrigger attachments were similar to those used on the front. Vertical angle brackets had been used in addition on the inner and outer faces of the nearside member. The strength of the joints was considered to be adequate.

3. Conclusions

3.1
It is considered that the repair joints attaching the front and rear outriggers were 'fit for purpose' except for the fatigue resistance of the front members to loads applied by the anti-roll bar in service if the car is driven hard on rough roads.
3.2
It is also considered that the front joints can be modified to make them more road worthy by introducing longitudinal straps across the welds, one on each side of the longitudinal folded and welded outrigger joints on each member. The straps must be attached by fillet welding along the full length of their sides and edges.
