Abstract
A hanger for a power factor capacitor and method of attachment by brazing reduces metallurgical changes that can lead to cracks in the tank wall from welding. The hanger has a base plate with a circular opening and a raised shoulder that provides a single ring of contact between the tank wall and hanger. A ring of brazing alloy is placed within the opening on the tank wall. Through induction of electric current, the brazing alloy melts and flows resulting in a complete braze between the hanger and the tank wall which is accomplished at a much lower temperature than other welding techniques.
