Bed spot welds

[Archive]

I was looking closely at the condition of my truck bed in preperation for a Lin-X install and noticed a possible problem. In each corner area, I noticed a series of 4 spot welds which looked like they were failing. Any comments? I would like to fix this before I install the expensive coating. Maybe I don't have to? All I have are questions.

There are are two common ways for aspot weld to fail, if it just falls apart the weld was poor right from the factory. If the weld was good, the area around the weld has to be cracked for it to fail. This could be from stress or vibration etc. The welds I think you are refering to, look like they have been heavily squeezed, this was probably due to poor parts fit up. This sort of weld is made by using a short heat cycle just to get the two sheets red hot and allow them to be forced together, the followed by the normal weld schedule.
If you feel that the welds may be broken, they can be easily re-welded from the broken side with a mig weld. Clean up the area prior to welding, any paint, oil, rust, dirt, must be removed, a small pencil grinder does a good job.
A local body shop should be able to do this for you.
