Discussion on “answers to some questions on electric arc welding,” (Lincoln), Cleveland, Ohio, March 19, 1915. (see proceedings for March, 1915)

E. S. Zuck: Mr. Lincoln states on the first page of his paper that all metals can be welded. This is true from a theoretical standpoint. Practically it is open to question, especially if the welding is to be done by the electric arc process. I would like to ask Mr. Lincoln whether he would recommend an electric arc welding outfit for a foundry or a machine shop doing cast iron work exclusively.
