Abstract
Abstract The method comprises deforming the end of the wire as by heating it above the melting point with a laser beam and permitting it to solidify into a sphere to raise the vaporization point of the end. The wire is placed into contact with the component and the wire and the component are heated by a laser beam to provide a fusion weld.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A method of connecting a wire to a component having a contact zone comprising heating a preselected portion of the wire to deform said portion to reduce the area-to-volume ratio of said wire to a point whereby the time to heat said portion to the vaporization point is increased beyond the time to melt said zone, placing said deformed portion in contact with said contact zone, and heating said deformed portion and said contact zone by means of a laser beam above their respective melting points to form a fusion weld.
Claim 2
Independent Claim
91 words
A method of connecting a wire to a component having a contact zone comprising heating a preselected portion of the wire to deform said portion to reduce the area-to-volume ratio of said wire to a point whereby the time to heat said portion to the vaporization point is increased beyond the time to melt said zone, placing said deformed portion in contact with said contact zone, and heating said deformed portion and said contact zone by means of a laser beam above their respective melting points to form a fusion weld.
Claim 3
Independent Claim
91 words
A method of connecting a wire to a component having a contact zone comprising heating a preselected portion of the wire to deform said portion to reduce the area-to-volume ratio of said wire to a point whereby the time to heat said portion to the vaporization point is increased beyond the time to melt said zone, placing said deformed portion in contact with said contact zone, and heating said deformed portion and said contact zone by means of a laser beam above their respective melting points to form a fusion weld.
Claim 4
Independent Claim
91 words
A method of connecting a wire to a component having a contact zone comprising heating a preselected portion of the wire to deform said portion to reduce the area-to-volume ratio of said wire to a point whereby the time to heat said portion to the vaporization point is increased beyond the time to melt said zone, placing said deformed portion in contact with said contact zone, and heating said deformed portion and said contact zone by means of a laser beam above their respective melting points to form a fusion weld.
Claim 5
Dependent Claim
19 words
The method of claim 1, in which said wire is heated by a laser beam above its melting point.
Claim 6
Dependent Claim
29 words
The method of claim 2, including the step of cooling said portion after heating the wire above the melting point, whereby surface tension draws said portion into a sphere.
Claim 7
Dependent Claim
23 words
The method of claim 1, in which said portion is heated above the melting point and below the vaporization point of the wire.
Claim 8
Independent Claim
109 words
A method of connecting a wire to a substrate having a contact zone comprising deforming the end of said wire to raise the time to reach the vaporization point of the end substantially above the time To reach the melting point of said contact zone, placing said end in contact with said contact zone, and heating said end and said contact zone by a laser beam for an interval sufficient to raise the temperatures of said end and said zone above their respective melting points but insufficient to raise the temperature of said end above said vaporization point to provide a fusion weld between said wire and said substrate.
Claim 9
Independent Claim
109 words
A method of connecting a wire to a substrate having a contact zone comprising deforming the end of said wire to raise the time to reach the vaporization point of the end substantially above the time To reach the melting point of said contact zone, placing said end in contact with said contact zone, and heating said end and said contact zone by a laser beam for an interval sufficient to raise the temperatures of said end and said zone above their respective melting points but insufficient to raise the temperature of said end above said vaporization point to provide a fusion weld between said wire and said substrate.
Claim 10
Dependent Claim
40 words
The method of claim 5, including the steps of deforming said end by heating said end above the melting point of said wire with a laser beam, and cooling said end whereby surface tension draws said end into a sphere.
