A METHOD OF END-WELDING METALLIC OBJECTS TO METALLIC SURFACES BY ELECTRIC ARC WELDING, COMPRISING ESTABLISHING CONDUCTING RELATION BETWEEN ONE END OF A METALLIC OBJECT HAVING SUCH END COMPLETELY METALLIZED WITH A METALLIC MATERIAL OF HIGHER ELECTRICAL CONDUCTIVITY THAN THAT OF THE OBJECT AND SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, TITANIUM, VANADIUM AND MANGANESE AND THEIR ALLOYS, AND THE SURFACE TO WHICH IT IS TO BE WELDED, PASSING WELDING CURRENT THROUGH THE OBJECT AND THE SURFACE AND FROMING AN ARC BETWEEN THEM, MAINTAINING THE ARC FOR A PREDETERMINED PERIOD SO THAT THE WELDING END OF THE OBJECT AND THE CRATER FORMED IN THE SURFACE MAY ACQUIRE WELDING TEMPERATURES, AND MOVING THE HEATED OBJECT INTO CONTACT WITH THE CRATER IN THE SURFACE, THE FLOW OF CURRENT IN THE WELDING CIRCUIT THROUGH THE OBJECT AND THE SURFACE BEING MAINTAINED AS LONG AS NECESSARY TO SECURE A SATISFACTORY WELD.
