pipe welding - Chrysler Voyager

Post

Hello guys,

I have a Chrysler Voyager. My problem is that the low pressure air con pipe has a slice cut, caused by the wiper linkage. I think all the refrigerant has leaked out of the sytem. Could be at one side.

my questions are:

is it safe to weld the hole in the pipe (aluminium)?
sould i use pipe clamps (such as **** )?

Thanks for your answers and greets from Germany,

herbert

Reason: Removed spam link to pipe clamp supplier. Sizes range from 27-355mm, that's a huge aircon system!

You can use a flare fitting.
It is safe to weld if you remove the pipe from the car.

Hi,

Two points:

1) unless you are 100% totally sure that no flameable gas or fluid of any sort, ever, has been in those pipes, get the pipe out of the car and fill it with sand/soil/flour or similar before you put any sort of flame near it. pipes exploding ruins a day and requires new underpants.

2) Welding is probably a bit too much effort - easy to blow out the pipe. I strongly suggest you use an aluminium brazing method instead. Most are fine with a regular butane flame ( actually - work better with regular butane ), and the brazing alloy will be stronger than the aluminium base layer.
Al Brazing with these rods is entirely black and white - it either works or it doesn't. the difference is how you prepare the metal. Clear up as normal, degrease etc, but the LAST act you do, before you put a flame to it, is scrub the area with a stainless steel wire brush. If you don't brush it, it won't work. If you use a brass brush, it won't work. Use a regular steel brush, it won't work. Use a stainless brush, it'll work perfectly.

Ya, it is safe to weld. It is preferred to weld away from the car to avoid further damage.

or look for another pipe at the car junkyard.
