Filed:

Apr 1, 2002

Appl. No.:

10/113861

Inventors:

Clarence L. Pyritz - Waconia MN
Frank G. Arcella - Eden Prairie MN
Michael A. House - Chaska MN

Assignee:

MTS Systems Corporation - Eden Prairie MN

International Classification:

B23K 2600

US Classification:

21912164, 21912166, 21912184, 21912185

Abstract:

A powder feed nozzle for laser welding applications including a multiple outlet nozzle tip for focusing a discharged powder stream. The multiple outlet nozzle tip disperses multiple outlet streams and includes a powder discharge outlet and at least one focus gas discharge outlet, radially spaced from the powder discharge outlet, for dispersing a powder stream and a gas stream. Powder flows from a powder source through a powder channel to discharge a powder stream. Focus gas flows through a focus gas channel angled relative to the powder channel to discharge a focus gas stream.

US Classification:

052/459000, 052/256000, 052/257000, 052/742130

Abstract:

A method of making a drywall joint includes steps of positioning a butt block that has a recessed surface on an interior side of a joint that is to be formed between a first drywall sheet and a second drywall sheet, securing at least one of the first and second drywall sheets to the butt block so that the secured sheet is made to conform in shape to the recessed surface, thereby forming a secondary recess on an exterior of the drywall sheet in the area at which the joint is to be made, and applying joint compound within the secondary recess.
