Zusammenfassung:	A method of sealing an annulus between first and second bore-lining tubulars comprises providing a first bore-lining tubular having a first volume of alloy thereon and running the first bore-lining tubular into a bore provided with a second bore-lining tubular. The alloy is fluidised and then allowed to solidify in an annulus between the bore-lining tubulars and bond the tubulars together. The alloy may be fluidised in the presence of flux.
