If the weld had just a little too much build up it may have created a notch effect at the edge of the weld. Insufficient preheat or post heat could contribute as well. Getting into alloy steels and specialty steels sometimes it doesn't take much for there to be issues. I've welded on vessels where very exacting procedures had to be followed and they had 3rd party inspectors come in to ensure they were followed. Your heat had to be within about 10 amps and they'd use clamp on meters to verify your amps. One of the things I noticed coming into play a lot starting in the mid 90's was shops had to have their welding machines calibrated so the settings on the dial were closer to what was actually being used. Without calibration you could have 5 or more identical welders all have different amps at the same setting. Of course in a field situation this isn't always possible.I'd have to look again. Maybe right at the T1 edge of the weld.
