Abstract
An improved method for joining together the edge portions of first and second panels includes applying a heat curable adhesive along the edge portion of the first panel and then abutting the edge portion of the second panel with the edge portion of the first panel so that the adhesive is interposed between the edge portions of the first and second panels and the adhesive spaces the panels apart and provides a gap between the panels. A brazing material is melted and fills the gap and the heating of the panels by the brazing causes at least partial curing of the adhesive so that the panels are joined together by both brazing and adhesive bonding.
Claims19
A method of joining together edge portions of first and second panels, comprising:
- applying a heat curable adhesive-sealer along the edge portion of the first panel;
- abutting the edge portion of the second panel with the edge portion of the first panel so that the adhesive-sealer is interposed between the edge portions of the first and second panels and the adhesive-sealer spaces the panels apart and provides a gap between the panels;
- and brazing the first and second panels together by depositing heated molten brazing material to fill the gap, and the heated molten brazing material heating the panels causing at least partial curing of the adhesive-sealer so that the first and second panels are joined together by both the adhesive and the brazing material side-by-side.
(canceled)
The method of clam 1 in which the edge portion of each of the first and second panels is a flange.
A method for joining together first and second panels having flanges extending along edges of the first and second panels, comprising:
- applying a heat curable adhesive-sealer along the flange of the first panel;
- abutting the flange of the second panel with the flange of the first panel so that the heat curable adhesive-sealer is interposed between the edges of the first and second panels and a gap is provided between the panels;
- and brazing the first and second panels together by depositing heated molten brazing material to fill the gap, and which heats the panels causing at least partial curing of the adhesive-sealer so that the first and second panels are joined together by both the adhesive and the brazing material side-by-side.
A method of joining together edge portions of first and second panels, comprising:
- attaching a wire of brazing material to a tape of heat curable adhesive-sealer so that the wire and the tape extend parallel to one another;
- positioning the tape to lie between and engage with the edge portions of the first and second panels and create a gap between the panels, with the wire positioned along the gap;
- and applying beat to melt the wire of brazing material and at least partially cure the beat curable adhesive-sealer so that the first and second panels are joined together by brazing and adhesive-sealer bonding.
A method of joining together edge portions of first and second panels, comprising:
- providing a wire of brazing material having a depending leg extending along the length thereof,
- assembling a strip of heat curable adhesive tape to the wire of brazing material by adhering the tape to the depending leg;
- adhering the strip of tape along the edge portion of the first panel;
- abutting the edge portion of the second panel with the edge portion of the first panel so that the tape is interposed between the edge portions of the first and second panels and the tape spaces the panels apart and provides a gap between the panels;
- and heating the brazing material to a molten state to fill the gap, and the heated molten brazing material heating the panels causing at least partial curing of the adhesive-sealer so that the first and second panels are joined together by both the adhesive and the brazing material.
