A physical assessment of the device identified that the weld does not cover the circumference of the entire impaction plate assembly, whereas, the welds from other lots of the same device do.In addition to the weld not covering the entire circumference of the impaction plate assembly, it is suspected that there was not sufficient penetration between of the weld to the base instrument, or of the weld to the impaction plate assembly.When reviewing the engineering drawing, it does not specify that the weld should cover the entire circumference of the impaction plate assembly, however it does state: "all welds to be completely sealed, free of gaps and seams, and polished to a satin finish".
