How To Weld Aluminum Evaporator Coil. The best methods for making field repairs of punctures in aluminum refrigeration coils for example are the conventional metal-repair Standbys - soldering and welding and the now-familiar adhesive bonding. The tubes are bent into U shapes and are stacked into a panel.
Adhesives mechanical joining ultrasonic joining soldering and brazing. Avoid pulling while weldinginstead push at a 10 to 15 degree angle. Aluminum is a popular material for refrigeration units because it has high heat conductivity high corrosion resistance and it can be repaired using standard procedures for aluminum.
Furthermore not sure how this stuff would work for joining two dissimilar metals together such as copper and aluminum but this is a plus for aluminum coils.

Aluminum or Copper coils --- and it will withstand 2000 psi and adhere. We use it to repair a leak in an aluminum coil as well as on a U-bend.
