ABSTRACT:
A method of joining a copper contact button to the aluminum headbar of an electrode plate used in the electrolytic industry for the recovery of nonferrous metals. The method consists in the steps of coating the copper contact button with a thin layer of silver, mechanically threading the copper contact button into the aluminum headbar, preheating the assembled copper contact button and aluminum headbar to a temperature ranging from 200.degree. to 900.degree. F, and welding the coated copper contact button to the preheated aluminum headbar. When arc welding, preheating in the temperature range 375.degree. to 475.degree. F prevents oxygen from the copper diffusing into the weld.
