just wondering if you can weld aluminum pipe to a metal pipe for a cars exuast
aluminum to steel? short answer No and you will end up with a lot of mess and splatter try J-B weld it's a product though it can be done with a certain process that I'm not familiar with I have seen the finished application but i think the aluminum is a different metal make up I have accidentally tried to weld the two together many times not realizing what the metals were use a magnet to test if its aluminum magnets wont stick to aluminum
i don't see why not becasue volvo uses aluminum exhaust systems.
