Brazing aluminum is a quick and inexpensive option for repairing leaks cracks or holes in aluminum and is often found in air conditioning repairs.
When you sweep the tip of the rod through the joint it should melt in.
When everything is cooled off you ll have a strong joint.
This paste is brushed sprayed dipped or flowed onto the entire area of the joint and brazing filler metal.
Aluminum brazing fluxes consist of various combinations of fluorides and chlorides and are supplied as a dry powder.
If not heat the joint more and check it again with another sweep.
Aluminum is a real challenge to join without specialized welding equipment.
