Abstract: A laser device is provided for performing an annular circumferential welding on a workpiece, and includes a laser head having a laser source configured for emitting a laser beam to perform welding around an outer circumferential target area of the workpiece. Also included is an optical reflector assembly having at least two optical reflectors spaced from the workpiece for reflecting the laser beam emitted from the laser head. The reflectors are spaced from each other, disposed on opposite lateral sides of the workpiece, and inclined relative to an axis transverse to a longitudinal axis of the workpiece so that the circumferential weld is achieved by a single cycle of the laser beam.

Abstract: A medical device, such as a vascular access device, is disclosed for providing access to a medical fluid flow path for the introduction or withdrawal of medical fluids to and from the flow path. The access device includes an indicator for providing a visual indication when the access device has been exposed to an antiseptic agent.

Abstract: A non-destructive plastic butt weld inspection method in which the weld bead 42 is removed from an exterior surface of a weld zone region 44 of a butt weld and the weld zone region 44 is heated to a temperature sufficient to visualize the weld zone 44. After heating, defective joints are readily identified by the appearance of a bond line 40 in the weld zone 44 while satisfactory joints merely show the weld zone 44 with no evidence of a bond line 40. Surface irregularities such as ridges 46 and indentations 48 may also form in the weld zone during the heating step.

Abstract: A method for production of simultaneous lap and butt joints directs electromagnetic radiation (12) through a radiation transmitting material (40) to an absorbing material (44a, 44b, and 44c) that absorbs radiation (12) with the generation of heat. The heat provides sufficient molten material in interfaces (50a, 50b, and 50c) to fuse and bond: 1) pipe ends (14, 24) to each other in a butt joint (22), 2) pipe end portion (16) to sleeve (40) in a lap joint (28a), and 3) pipe end portion (26) to sleeve (40) in a lap joint (28b). Use of a sufficiently clear material for sleeve (40) allows visual inspection of joints (22, 28a, and 28b). Butt joint (22) can be formed by conductive heating without absorbing material (44a) to provide a smooth interior bore useful for transporting high purity fluids without risk of absorbent contamination or debris and organism collection in gaps found in previous joining techniques.

Abstract: A method for production of simultaneous lap and butt joints directs electromagnetic radiation (12) through a radiation transmitting material coupling (40) having an absorbing material (44) formed as a portion of coupling (40) that absorbs radiation (12) with the generation of heat. The heat provides sufficient molten material in interfaces (50a, 50b, and 50c) to fuse and bond: 1) pipe ends (14, 24) to each other in a butt joint (22), 2) pipe end portion (16) to sleeve (40) in a lap joint (28a), and 3) pipe end portion (26) to sleeve (40) in a lap joint (28b). A coupling (40) is preformed with integral or surface applied radiation absorbing material (44) to provide rapid joint assembly and consistent weld production.
