摘要： The invention relates to a fixture that reduces the heat transfer between a thermally conductive work piece, such as a copper tube, and the fixture. In one embodiment, the fixture includes a pair of collet members, with each collet member having at least one work piece engaging protrusion, and a clamping mechanism that urges the collet members toward each other to engage and clamp the work piece between the collet members. The contact between the work piece and the protrusions of the collet members inhibit additional surface contract between the work piece and the fixture, reducing the heat transfer from the work piece to the fixture during welding.

摘要翻译： 本发明涉及一种减少诸如铜管的导热工件与固定装置之间的热传递的夹具。 在一个实施例中，夹具包括一对夹头构件，每个夹头构件具有至少一个工件接合突起，以及夹紧构件，其将夹头构件朝向彼此推动以将工件接合并夹紧在夹头构件之间。 工件与夹头构件的突起之间的接触阻止了工件与夹具之间的额外的表面收缩，从而减少了焊接过程中从工件到夹具的热传递。
