Excavator Bucket Repair

IMG_1117

The wear plates on this bucket were obviously worn.  The way the wear bars were installed from the factory was not the best way.  When the bars are installed parallel with the flow of the material they do not protect bucket well.

We removed the damaged wear bars and installed new wear bars perpendicular to the flow of material.  The reason this configuration is better is the dirt (in this case) will get caught between the the bars and protect the bucket bottom.  The material then is wearing against the hardened wear bars and dirt.

Structural Steel Erecting in Sacramento

Some of you may guess the small building we are working on.  I’ll give you a hint – you can see the color of the joist used for this auto parts store.

Dan and Karl shook the deck out and tacked down in one day.

We came back about 1-1/2 months after we finished the deck to install these two awnings.

 

Welding on a Lattice Cell Tower

The rusted looking areas are the locations we need to weld

This is the base of one of the legs of a three legged tower we worked on in May, 2012.  This tower is in Fortuna, CA just south of Eureka.  The weather was very nice for working when I was there, overcast and cool.  However, when Dan was there they couldn’t work one of the days due to rain and wind.  All the welding was done using flux core wire, E70T-8.

 

Cell Tower Modification in Modesto

On this cell tower we added 12 gussets to the base plate of the tower and reinforced the port holes.

This was the easy side to get to

The gussets are about 6″ wide at the base and approximately 14″ tall.

I had to make like a mole to get in this hole

Sometimes half the battle is getting to where you need to be and then to see the joint that needs to be welded.

 

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.

all threads welded back on bronze place marker

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.

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.

Certified Pipe Welding in Sacramento

Dan and I installed this valve assembly Thursday, 2/3/11.

From start to finish we completed it in about 12 total man hours.

We supplied and installed 3 – 6″ flanges, 2 – 90 deg. elbows,  and about 11′ of 6″ pipe.

Dan cut into the existing pipe for the valve assembly and 6″ pipe, then we worked together to fit the pieces in.

Dan completed the project by welding everything up.

Both of us enjoy this type of work and were satisfied with the finished product.
