Welded girder photos.
Photo 1. The rail is still attached to the beam in this photo. The 3/8" x 6" x 12" gussets are visible. The spray pattern from the painter or perhaps the wire buffing wheel marks are beginning to emerge in a rust pattern. The rust is minor.
Photo 2. Shows fillet weld on 3/8" x 6 stiffner and fillet weld at web and flange connection. Also shows how angle diagonal braces were torched off. The paint is thin and just a little rust is showing through.
Photo 3. A girder with the catwalk, rail and buss bar still attached. We unbolt the rail and torch off the other attachments close to the flanges but not cutting into the beam in any way.
Photo 4. Shows how the end plate on the beam is lower than the top flange. The End Plate is the bearing surface as it sticks down below the bottom flange and is milled off on the bottom. The idea is to make the tops of all of the beams equal in height by milling the bottom. (The different thickness of flanges on the various beams would make the top elevation of the flanges different. By milling the plate to compensate for the difference the top height on all of these beams is identical.
Photo 5. The fillet weld on the inside of the end plate. Also a rust streak that apparently bled down from the rail.
Photo 6. I think this is an expansion joint detail. They had a gap in the 1,250’ runway system to allow for expansion and contraction. The black in the photo is actually mildew since this location is located in the heart of the Oregon rain country…Gardner, Oregon. (Southern Oregon Coast).
Photo 7. Another shot of the stiffner showing the nice welding job. Again, the black is dirt or mildew.
Photo 8. This is the mate to the expansion joint photo. At the bottom of this end is a mirror image of the previous angled expansion joint.
Photo 9. The very end beam on the runway. Showing welding of the end plate onto the girder.
Photo 10. This shows how the stiffners are spaced. Again, the rust is not worse than what appears here. There is little or no pitting.
Photo 11. Taken this summer under better lighting condition before removal began.
Photo 12. 1,250’ long runway to support two 25 ton by 100’ span cranes. The operation was set up to process very large Douglas Fir timbers. A few of the timbers are visible under the runway.
