Method of brazing and apparatus

A method of bonding a tubular element to a flat element having a hole therein for receiving said tubular element;

• said method comprising the steps of:
• forming a circular depression shaped as a fillet around said hole in a first surface of said flat element;
• forming protruding material shaped as a fillet around said hole in a second surface of said flat element opposite said formed fillet in said first surface of said flat element;
• inserting said tubular element into said hole of said flat element so that an inner surface of said fillets and an inner surface of said hole of said flat element each comprises a mating surface that is abutted to a mating exterior surface on said tubular element;
• and
• subjecting said fillets of said flat element and said tubular element to a bonding operation wherein said mating surfaces of said fiat element and said fillets are bonded to a said mating exterior surface of said tubular element;
• said fillets being effective for providing bending stress reduction in said tubular element immediately adjacent the portion of said tubular element that is bonded with said fillets.

Apparatus comprising

• a first element and a second element said apparatus produced by the steps of:
• forming fillets in said first element wherein a depression defines material shaped as a fillet in one surface of said first element and a protrusion defines material shaped as a fillet in a second surface of said first element opposite said depression defined fillet material;
• abutting a mating surface of said fillets and a mating surface of said first element against a mating surface of said second element;
• and
• bonding said mating surfaces of said fillets and said mating surface of said first element to said mating surface of said second element.

Apparatus including a flat element bonded to a tubular element, said apparatus produced by the steps of:

• forming a first circular fillet defined by a depression around a hole in a first surface of said flat element;
• forming a second circular fillet comprising protruding material formed as a fillet around said hole in a second surface of said flat element opposite said depression defined fillet in said first surface;
• positioning said tubular element into said hole of said flat element as well as into said first and second circular fillets;
• abutting a mating surface of each of said fillets and a mating surface on an inner surface of said hole of said flat element to a mating exterior surface on said tubular element;
• and
• bonding said fillets and said fiat element and said tubular element wherein said mating surfaces of said flat element and said fillet are bonded to said mating exterior surface of said tubular element.

A method of bonding a brace bar of a Coriolis effect flow meter to a flow tube of said Coriolis effect flow meter for increasing the operational bending stress in said brace bar and decreasing the operational bending stress in said flow tube, said brace bar having a hole therein for receiving said flow tube, said method comprising the steps of:

• preforming a fillet having a hole therein,
• abutting said preformed fillet against a first surface of said brace bar so that said hole of said brace bar is in axial alignment with said hole in said preformed fillet,
• forming a depressed circular fillet around said hole in a second surface of said brace bar;
• inserting said flow tube into said hole of said brace bar and said hole of said fillet so that an inner surface of each of said fillets and an inner surface of said hole of said brace bar each comprises a mating surface that is abutted to a mating exterior surface on said flow tube;
• and
• subjecting said fillet and said brace bar and said flow tube to a bonding operation that reduces the operational bending stress in said flow tube and increases the operational bending stress in said brace bar wherein said mating surfaces of said brace bar and said fillet are bonded to a said mating exterior surface of said flow tube.
