Abstract

Composite solder articles contain a first portion of a first solder having a first melting point, T.sub.1, and a second portion of a second solder having a second melting point, T.sub.2, which is at least (T.sub.1 +10).degree. C. Such articles are useful as the sole solder-producing inserts in heat-recoverable solder connection devices. When the device is heated, the second solder will not melt until the first solder has melted and flowed. Thus the second solder portion can indicate when the first solder has flowed, and/or can control flow of the first solder.

Claims13

Dependent claims

A device for forming a solder connection between a plurality of elongate bodies, comprising a dimensionally recoverable article into which part of the bodies are insertable, the article containing an annular composite solder insert comprising:

a first annular portion for forming a solder joint between the bodies formed form a relatively low melting point solder;
and
a second portion comprising an annular flange joined to the first portion;
wherein the second portion is formed from a relatively high melting point solder which, when the device is heated in use, will not melt until after the relatively low melting point solder has melted and flowed.
