Welding on a BMW
Posted: Mon May 12, 2014 11:52 am
I need to get some welding done to fit a small patch on the 3-er and not having either the knowledge or training to do it myself (though it seems - and I stress 'seems' to be simple enough) I thought I would ask any if those on here who do have such knowledge for their guidance.
The car has a small hole punched through the outer sill by a jacking accident, and though I'm not sure if it is an MOT fail, I want to get it patched if only for enduring long term integrity.
I'm thinking that either MIG or TIG would be better than good old arc (and neater too) but with so many delicate electronic items on the car there must be precautions needed. Is this no more than completely disconnecting the battery or does more need disconnecting?
I'm keen to avoid a body shop due to their high charges so will try to find a local welder with the right skills. Obviously I will need to prepare the metalwork be cleaning it back to bare metal and get some more if the right steel to provide a patch and once it's all in place grind it back smooth and paint it with the appropriate paints. The damage is completely behind and protected by a plastic sill cover so less impacted by corrosion than it would be if the area was the outer part of the car.
Any thoughts? Anyone know of a decent repairer who can do this, or is it really a job for a BMW body shop even if I do the prep and then repaint it afterwards?
Or are any of you folks in range of the Bedford area and have the skills & kit?
I may just have to bite the bullet and go to a body shop.........
