<p>A method of rebuilding a strip mill guide formed principally of copper and having lead therein, and having longitudinally extending irregularly shaped grooves therein forming a longitudinally extending channel comprises the steps of preheating said strip mill guide, providing a welding rod formed principally of copper and having a diameter of one quarter-inch, positioned in an electrode holder, establishing conductors between said electrode holder and a source of arc welding electric current and said strip mill guide, delivering said arc welding electric current to said welding rod and moving said welding rod along said grooves and channel in said strip mill guide so as to maintain an electric arc whereby said strip mill guide is heated and said welding rod is melted and deposited in said grooves and channel.</p> |
