Plastic component for laser welding onto second component to produce automobile bumper has integral flexible connector pressed against second component for welding operation

The first component(1) has one or more flexible connectors(3) which can be bent towards(5) a second component(2). A tool(6) presses each connector into contact with a second component so that the welding operation can join the contacting areas. Each connector(3) comprises a flexible finger forming a...

Zusammenfassung:	The first component(1) has one or more flexible connectors(3) which can be bent towards(5) a second component(2). A tool(6) presses each connector into contact with a second component so that the welding operation can join the contacting areas. Each connector(3) comprises a flexible finger forming an integral part of the first component(1). An opening(7) associated with each connector enables the tool(6) to press against the connector during welding. Each connector is welded onto the second component using a laser(4). An independent claim is included for a process for welding together plastic components in which: a) the components are positioned relative to each other in suitable positions; b) at least one connector(3) forming part of the first component(1) is pressed into contact with the second component(2); c) the connector is welded onto the second component. Bei einem Bauteil (1) aus Kunststoff ist zum einfachen und spaltfreien Positionieren des Bauteils (1) beim Anschweißen an ein weiteres Bauteil (2) mindestens ein mit dem Bauteil (1) verbundenes, in einer Anpressrichtung (5) relativ zu dem Bauteil (1) bewegbares und für ein Anpresswerkzeug (6) zugängliches Verbindungselement (3) vorgesehen. Dadurch, dass die Verbindungselemente (3) relativ zu den Abmessungen der zu verbindenden Bauteile (1, 2) klein sind, können diese trotz Bauteiltoleranzen beim Verschweißen der Bauteile (1, 2) einfach und spaltfrei positioniert werden. Ferner wird ein Verfahren zum Verschweißen von Bauteilen (1, 2) aus Kunststoff mit großen Abmessungen angegeben.
