ABSTRACT:
A process is disclosed for joining narrow width thin gage metal or alloy strip end to end to form an elongated coil. The trailing end of a first strip segment and the leading end of a second strip segment are cut so as to match when placed in a butting relationship and to establish a joint between the strips. A preselected gap is established between the butting ends and a braze material is inserted in the gap. After heating to braze the strip segments together, the brazed joint is hammered to reduce the joint geometry to that of the parent metal strip segments.
