Show ahline ch line nickel with iron the great value of nickel as i coating for iron has led to experiment to sec it it could bo to tho surface oc wire iron by some mechanical in place or alie usual plating process hie experiments appear to be so successful that both nickel anil cobalt ciare been welded to iron and the united metals have been afterward stamped and rolled into various shapes seeh ns plates kettles and kitchen utensils and ill awn into wire having an iron covered by a nickel or cobalt skin alays of also leavo been made anil these alloys leavo been used to weld with iron cobalt alloyed with zinc also lias been welded to iron in all these experiments it appears to bo essential that during tho welding under the or rolls tho air must bo excluded chis has been done by wrapping lie iron and nickel buforo welding in iliin sheets of iron tho aroa skin was welded on at the samo time but was removed afterward by dissolving the outer skin of iron in ho nickel surface under il not being affected by abo acids another method used to exclude the air during welding is to heat the iron and nickel in an atmosphere mo sphere of carbonic oxide or caiby acted hydrogen it arns also found that pure nickel could bo welded over a core composed 0 an alloy of nickel and copper the experiments were conducted by dr theodor of germany and arc regarded as opening a wide nold for commercial enterprise in tho manufacture ot nickol phileda stamped waro and nickel covered wiro A gentleman sent a copy of brown ass mss first acknowledged work to tom hood who was then confined to his bed by illness thinking that it might amuse tho patient the story is told that hood took up the volume and having it for a few minutes handed it to his wife read my dear read ho exclaimed with 1 wild look in his mrs howl soon appeared to bo absorbed in ival akel hood anxiously after a paine well why replied in doleful tones mrs H I 1 cant mako out n of it A aish of relief burst from her nui band thank JT cricri di iberi have not lost my reason |
