Trash Enclosure Gate Repair

They say a picture is worth 1000 words so, I don’t think I need to add much to it.

We took the damaged gates and disposed of them at the metal recycler.

These replacement gates were fabricated in our shop then installed.

Bronze place marker repaired

We do quite a bit of work for a local cemetery, from working on their trailers to mowers.  This is a bronze place marker for one of the graves.  While mowing the lawns they drive over these place markers and eventually break off the bolt attachment.

Typically the heat from the welding would discolor the top side.  We remedy that by using several wet rags as a heat sink and put small stitch welds a little at a time on each all thread in rotation.

We used an aluminum bronze welding wire .035 diameter and straight Argon as the shielding gas.

Water Tower Repair

We were called out by a Fire Prevention Company to repair some holes in a water tower.  Interestingly enough, they found us on the Google search.

They didn’t want a sprinkler tank any more

Several of the holes Dan was able to patch using one patch, however there were many which required one hole one patch.

several patches

It is always nice to work for a new company and have the opportunity to build a new relationship.  Once they put some paint on this tank it would be difficult to see the repairs without standing right next to it.

Dan used E6010 welding rod which is used in many different applications including gas line and water lines.  It is a nice rod to use when welding on thin material.  The patches are  10 gauge sheet metal which is the approximate thickness of the tank walls.  10 gauge is nearly as thick as 1/8 inch.

Stake side replacement

A local delivery company did not like the usability of the stake sides on their flat beds.

Typical stake sides on flat bed

They had several concerns –

1.  With use the panels became out of square and so were difficult to take out and  put back in

2.  Loss of panels when they were miss placed

3.  Damage to panels when they were not removed and placed carefully in stacks

4.  Sometimes the panels would only fit in one location which at times made it difficult to put the panels back in if they didn’t remember where each came from.

We feel they now have a system which remedies these concerns

Hinged trailer side panels in the up and locked position

This is a 48 foot flat bed trailer, it has a total of 12 – 4’x8′ hinged panels on the sides.

Hinged Side Panel in the down position

Each Panel can be taken down individually

Close up of safety pin and sleeve welded into trailer rail, two of which are on each side panel

Each panel has the typical slide lock at the top corners but also has two safety pins at the bottom.  This allows the driver to unlock the panel at the top with out fear that the panel will swing down on its own.

Chiller base modification

Modified the base attachments on two Chillers in Milpitas.

We drilled 12 inches into the concrete and epoxied a 5/8″ stainless steel all thread using Simpson Set XP epoxy.

The initials CEL where written by the inspector indicating the welds passed inspections.

There were 8 total locations

I used E7018 welding rod, a rod which can be used in all Structural applications were mild steel is being welded.

Structural Fabrication 1st Quarter 2012

Structural Fabrication for the Department of Water and Fish and Game

The structure in the background of this picture is a completed frame with catwalk.

These frames hold culverts in the Delta near Stockton.  We built 4 total frames.

The dimensions are 5 feet tall, 11 feet wide, 60 feet long, and weighed approx. 16,000 lbs.

The frames where made mostly using 4″x8″x1/4″ rectangular tubing and 4″x6″x1/4″ rectangular tubing.

The majority of the project was welded using NR232.  This welding wire is approved for all structural applications.

Certified Welding at Cell Phone Tower

We were awarded the contract to do the cell phone tower modifications at a site in LA.

First I had to become an LA Certified Welder.  That was not a problem but very involved – I had to make a special trip to LA, do a welding test I had already completed for my AWS welding certification, and a 50 question test.

The contract required us to install 12 – 1-3/4″ x8′ anchor rods and weld 6 large gussets equally around the tower 20′ high.

To install the anchor rods we had to remove the grout from under the base plate.

The rods needed to be epoxied 7′ into the existing foundation with is 22′ deep.

Before we installed the rods I cut a bevel on the end of the rod so it would go into the epoxy easier without leaving any air bubbles in the epoxy.

Rods epoxied into the foundation

Before installing the gussets I needed to remove all the galvanizing from the plates and the tower  in the weld area so the galvanizing would not contaminate the weld.

I then used a crane to “fly” the gussets in to place.  It took only about 1 1/2 hours to fly all the gussets in.

Welding the gussets in.  I bounced around the tower as I welded so the tower would not get too hot in any one area.

Welding completed and painted.  I also caulked the areas with silicone which were not welded where water could get between the gusset and the tower to keep the rust out.

All told this was a nice project and I enjoyed doing the work.  From coordinating the equipment, subcontractors, and materials to installing the anchors, welding the gussets, and getting final inspections everything what quite well.
