THE METHOD OF JOINING A FIRST METALLIC MEMBER TO A SECOND METALLIC MEMBER WHICH IS SUSCEPTIBLE TO SUBSTANTIALLY INSTANTANEOUS SURFACE REACTION WITH ATMOSPHERIC ELEMENTS WHICH COMPRISES: CLEANING A PART OF THE SURFACE OF SAID SECOND METALLIC MEMBER TO REMOVE THE REACTION PRODUCT OF SAID SURFACE REACTION; COATING THE CLEANED SURFACE OF SAID SECOND METALLIC MEMBER WITH A METAL WHICH HAS A MELTING POINT SUBSTANTIALLY LOWER THAN THE MELTING POINT OF SAID METALLIC MEMBERS AND WHICH IS A SOLID AT AMBIENT TEMPERATURES TO PROTECT THE CLEANED SURFACE FROM CONTACT WITH THE ATMOSPHERE; PLACING SAID FIRST AND SECOND METALLIC MEMBERS IN AN ENVIRONMENT OF INERT GAS WITH SAID FIRST METALLIC MEMBER IN CONTACT WITH THE METAL COATED PORTION OF SAID SECOND METALLIC PORTION; AND JOINING SAID FIRST AND SECOND METALLIC MEMBERS TO EACH OTHER AT THEIR POINT OF CONTACT IN SAID INERT GAS BY A JOINING PROCESS ENTAILING THE APPLICATION TO SAID SECOND METALLIC MEMBER OF SUFFICIENT HEAT TO LIQUEFY SAID COATING METAL WHEREBY SAID METAL WILL GRAVITATE FROM SAID SECOND METALLIC MEMBER, EXPOSING A FRESH CLEAN SURFACE.
