London, England – An experiment at research firm Thatcham showed how inferior welding on car repairs can be highly dangerous.
The Dangers of Bad Welds- 6/18/2009
Two identical cars were subjected to crash tests at 30mph to replicate a T-bone accident at road junctions. Prior to the test, one was repaired to U.K. industry standards while the other’s central door pillar was welded using the wrong tools and materials.
The results showed that the driver in the properly repaired car would have come out unscathed. However, the car with the badly-welded bodywork sustained 70% more cabin intrusion. Upon impact, the spot welding tore apart, the sill buckled and the door pillar collapsed. The driver would have suffered 20 extra G forces, which mostly likely would have been fatal.
