    Default Welding Works in Solar Flat Plate Collector

    G'day..

    I have few clarifications about welding of copper in solar thermal collectors..
    I've checked few threads about copper piping, but I want to know which is the best for welding the copper riser to the copper header..
    regarding the risers with the absorber, I do know that ultrasonic is the best, but in case this is not available, what is best??

    Thank you in advance..

    I would use silver solder (brazing) to weld the tubes into the tank, the same stuff used for plumbing and hydraulic fittings.
