Optimizing weld seams in plastic component including e.g. fuel filter and/or fuel filter housing, by determining weld seam geometry, and determining loading capacity/strength of weld seam defining parameters such as bursting pressure

摘要

The method comprises determining a weld seam geometry, determining a loading capacity/strength of the weld seam defining parameters such as bursting pressure, selecting a material layer having a minimum thickness, selecting a weld path depending on the fixed material layer, where the material layer and the weld seam geometry are welded, selecting a weld time depending on the material layer, determining the welding parameters as a function of the selected welding process associated with the selected material layer, and determining the parameters depending on a selected welding device.

The weld path is greater than or less than 0.5 mm. The weld time includes a melting time, a holding time and/or a joining time, where the holding time is 2-4 seconds. The welding process includes: an ultrasonic welding process, which is carried out for a duration of 0.1-2 seconds; a laser welding process, which is carried out for a duration of 0.2-5 seconds; a linear vibration welding process, which is carried out for a duration of 0.2-7 seconds; a spin welding process, which is carried out for a duration of 0.1-10 seconds; a high frequency welding process, which is carried out for a duration of 0.1-5 seconds; a heating element welding process, which is carried out for a duration of 10-20 seconds; a friction welding process; and a high-frequency welding process. The friction welding process is carried out with an amplitude of 1.2 mm. An independent claim is included for a component comprising two parts to be joined together.
