This article illustrates the necessary steps that manufacturers must take to validate their laser-welding process and highlights the steps they should consider to conduct successful validations. While the terms validation and verification are often used interchangeably, they have very different meanings.

The weld-junction gap passed, the maximum range limit value was 0.050 mm, and the actual weld-junction fit-up range was 0.025 mm This process begins with selecting the weld-quality metrics, which should represent the stresses and physical limitations to which the final laser-welded product is subjected by the end user.

This surgical tool is pressurized during the procedure and must be free of voids, even if the voids do not leak.

Manufacturers should validate their laser-welding process for four reasons:, the validation process consists of six main components: the validation plan, equipment installation qualification, equipment operational qualification, process qualification, process validation, and product performance qualification.

Each component contains its own protocol, data, and report, and manufacturers may implement them in different ways to accommodate their design and manufacturing processes.

Next, manufacturers should select which input factors to fix or hold constant.

In this case study, the rotational speed of the tip/shaft assembly and the pulse repetition rate control the percent weld-spot overlap.

The surgical tool shown in In addition, the insertion process must minimize the weld-junction gap between the tip and shaft because a gap can cause voids and expulsion.

Previous studies involving this surgical tool showed that the laser-welding process can tolerate a maximum weld-junction gap of 0.05 mm.

Manufacturers should verify and document in the equipment operational qualification report that the entire welding system produces the programmed laser-welding parameter power over the projected operating ranges on a repeatable basis.

Because many laser welds are sensitive to the weld-junction gap and the weld-spot location on the weld junction in the x, y, and z axes, gauge R&R (or ANOVA gauge repeatability and reproducibility) studies must be conducted on the laser-welding system to establish its ability to produce the correct weld-junction gap and weld-spot location.

For this example, two weld-quality metrics were selected: minimum burst pressure and absence of voids.
