FAQs
Why is aluminium hard to solder?
Aluminium forms an oxide layer instantly, so solder does not wet it properly — ultrasonic welding breaks the oxide mechanically instead.
Is flux used?
No. Avoiding flux is a main reason aluminium harnesses are welded rather than soldered, since flux residue corrodes aluminium.
Can aluminium be welded to copper?
Yes — Cu-Al transition joints are a standard use of this machine.
