Miss Alignment can be a bad B…
…Bedevilment.
Another welder (day shift) and I (night shift) were welding foremen on performing non-stop, 24 hour a day, 30” suction and discharge tie-in welds on a turbine pump.
No restraints of any kind are allowed.
From the start of welding until finishing 3 days later (record time) the shaft or casing could not deflect more than 0.002 inches in any direction while the two welds were being made and completely cooled.
When a 30” pipe is welded directly to the pump flange,… See More
any misalignment or weld shrinkage can pull the pump out of square, warping the casing or discharge head and destroying shaft alignment.
My coworker began the process on day shift. He solved the problem of movement by simply keeping both welds near molten hot with welding until hand-off to me at start of night shift.
As his crews’ welding began to cool, here came Miss Alignment. In deathly spades.
In other words, he knew nothing about making controlled welds but he certainly knew how to create what began one of the biggest battles and longest nights of my welding career as I struggled to determine and then direct my fitters and welders in what needed to be done to stay within tolerance.
