What x-ray system are you using? Check out Dage. I bet you have voids...just can't image them. Why the fuss over voids? Voids terminate the crack propegation and can extend the time to failure for creep fatigue. I would not be concerned unless yo

Hi, Ours are inline, and depending on how you have the conveyers, you might need to use the data sheets to work out placement. If your running the conveyers behind the machine, then most of the machine is in front of the conveyer, so they use more s
