(Below) Just so you have an
idea how big this stuff is, these trunnions are
11" in diameter and the plate is 24 inches
square and 2" thick. The gap under the trunnion
will be full penetration welded to the plate.
(Below)Here
you see the top lug and the bottom lugs. The
markings on the end of the beam will be beveled.
This will allow Mike M and Mike S to full penetration
weld the trunnion plates to these beams.
The threaded hole in the one on the right is
2-1/2" diameter and will allow the lug to be
adjusted on the beam to assure a level lift.

This welding system allowed the two Mike's to
put down 3500 feet of weld and 250 lbs
of weld wire in 5 days. Four corners of beam 27
passes total on each corner.
NOW
THAT'S PRODUCTION!!
