Abstract

AN ELECTRICAL - RESISTANCE WELDING STRUCTURE OF A PART, SUCH AS A MAGNETIC HEAD, PROVIDED WITH A CASE AND A BASE, WHEREIN THE WELDING CONDITIONS ARE WIDENED AND THE WELD STRENGTH IS INCREASED AND STABILIZED. A SMALL PROJECTION ( 11 ) IS ARRANGED ON A BASE ( 10 ) AND THE SURFACE OF THE PROJECTION ( 11 ) IS FORMED TO BE, FOR EXAMPLE, CYLINDRICAL. A CURVE PORTION ( 3D ) ON THE SURFACE OF A FOLDING PORTION ( 3C ) AT THE BOUNDRY BETWEEN A BOTTOM SURFACE ( 3A ) AND A LATERAL SURAFCE ( 3B ) OF A SHIELD CASE ( 3 ) PROVIDED FOR A MAGNETIC ( 1 ) ABUTS AGAINST THE SMALL PROJECTION ( 11 ). THEN, THE CURRENT FLOWS BETWEEN THE SHIELD CASE ( 3 ) AND THE BASE ( 10 ) TO GENERATE HEAT IN THE ABUTTING PORTION DUE TO ELECTRICAL RESISTANCE,THEREBY WELDING THE TWO COMPONENTS. THE HEAT GENERATED BY ELECTRICAL RESISTANCE IS LESS LIKELY TO ESCAPE FROM THE FOLDING PORTION ( 3C ) OF THE SHIELD CASE ( 3 ), THUS MAINTAINING GOOD HEAT BALANCE BETWEEN THE FOLDING PORTION ( 3C ) AND THE SMALL PROJECTION ( 11 ), THEREBY PERFORMING STABLE WELDING.( FIG 2 )
