Hi folks

Some of you will think this is a silly Question but never mind here goes.

Is their a safe way to electric weld on cars with a on board ecu

On trucks it is ok to weld provided you disconnect battery and put your earth clamp close to your welding area.

Any body no what the official method is

This problem has appeared because the front exhaust down pipe bracket has broken off both the pipe and bracket look to be good metal, I do not want to buy new down pipe, but do not want to put my ecu at risk either

I would be grateful for any information and thanks for any help offered

Thanks Skodaman 61

If your worried about blowing ecu, just disconnect it while you weld it up, when i welded captive bolts into subframe for s3 lower brace i just pulled key out and disconnect battery and it was fine

If your worried could you not take it off to weld it? When you say electric weld do you mean mig or arc? You'll probably struggle with arc but can be done if your good with it. Ive mig welded quite a few different things on cars and always just disconnect the battery, never had a problem yet

should be no problem at all mate I've welded up lots of the octy front pipes with no problem, just disconnect the battery and make sure the earth clamp is close to the area to be welded

OT, why weld them ??
