METHOD OF FORMING A SEALED JOINT BETWEEN A TUBULAR ARTICLE AND A SHEET ARTICLE

A method of forming a sealed joint between a tubular article (10) and a thin sheet article (14) wherein the articles (10, 14) are made of metallic materials that are capable of fusion welding together. One step in the method involves locating an end of the tubular article in a collar (20) surroundin...

Zusammenfassung:	A method of forming a sealed joint between a tubular article (10) and a thin sheet article (14) wherein the articles (10, 14) are made of metallic materials that are capable of fusion welding together. One step in the method involves locating an end of the tubular article in a collar (20) surrounding a hole (12) formed in the thin sheet article (14). An end (22) of the tubular article (14) is positioned to lie substantially flush with a proximal end (24) of the collar (20). Next the ends (22, 24) of the collar and the tubular article are fusion welded forming a circumferential bead (26) creating an integral joint. Consequently in effect the previously separate a tubular article (10) and a thin sheet article (14) become a single piece.
