Many customers involved with laser welding measure the pulse energy output of their lasers, but is this all the data required needed to ensure quality welds? Steve Schellenberg at Spinal Modulation had his doubts. While he found pulse energy measurement using his Ophir equipment useful in qualifying his laser welding process, two of his laser welding stations were producing different quality welds despite producing identical laser pulse energies. One laser welder seemed to be doing an OK job, while the other welder produced significantly lower quality welds. Steve suspected differing laser profiles might be the culprit and invited an Ophir representative in to characterize the profiles of each welding laser.
