Abstract:
A method of frictionally bonding a liner to a length portion of an outer tube of a weapon barrel, comprising the following steps:(a) providing an outer tube having an inner diameter;(b) providing a liner having an outer diameter, a central length portion and two terminal length portions flanking said central length portion;(c) cooling the liner to a temperature of less than -50.degree. C.;(d) heating said length portion of said outer tube to a temperature such that said inner diameter of said outer tube becomes larger than said outer diameter of said liner;(e) introducing said liner into said outer tube while maintaining the temperature of said outer tube constant; and(f) discontinuing step (d) and cooling said outer tube such that shrinkage of said outer tube onto said liner first occurs along said central length portion of said liner, followed, after a predetermined period, by a shrinkage of said outer tube onto said liner along said terminal length portions of said liner.
