My guess is that the "pressure pig" was being forced through the line and it ended up parked too close to the unfinished "joining"...it's not the welder/fitter's fault that this splice joint blew out, no doubt he was in the "root pass" stage...may seem like someone doesn't know how to weld but the "tack" spots and preliminary root pass did hold that line together until the pig pressure overcame the integrity of the weld. After 4 years of pipeline construction that's my guess anyways.
