A client in Fremont, CA had a requirement to add two HVAC (Heating, Ventilation, Air Conditioning) units onto their roof. We were called in to weld the structural steel reinforcement for these two units. We brought in the steel and cut the beams onsite. After the beams were cut to fit and welded into place, we opened the roof for the HVAC curbs to be installed. Welding the W10x15 I-beams was done with ER7018 filler as per engineering requirements.
Dock Plate Repair:
This dock plate repair was done to control rodent access to the interior of the dock. There were gaps between the frame of the dock plate and the dock plate itself. These gaps allowed access for mice and rats to enter the building.
We brought some 1/8th” diamond plate to match the existing plate. There were several ideas about where to weld the space fillers. We decided to weld butt joints so the dock plate could still be used “below dock level”.
I got a call for some welding repair on a dumpster enclosure today. When I arrived it was easy to spot the gate without the padlock eye. It had been broken off by vandals. I cleaned up the area to weld a new eye in place. Fortunately I brought some 1/4″ flat bar and a plasma cutter. I was able to fabricate a new eye in about 10 minutes. Then the customer wanted a box to cover the padlock. I took measurements and returned to the shop where I had 1/8″ diamond plate in the scrap pile. I fabricated two lock boxes and returned to the job site to weld them in place.
