Rebar Welding

Rebar Welding:

This rebar welding job in Oakland, CA is well underway.  The building is being renovated which includes seismic retrofit.  Whiteside Concrete Construction blasted through the concrete walls exposing the rebar to be welded.  Before welding, we removed a bad section of #14 bar.  With the approved WPS (welding procedure specification) and PQR (procedure qualification record) in hand, welding begins.

Welding grade 60 rebar is typically done with an E9018 electrode.  However, this building is older and was constructed with grade 40 rebar.  Therefore, the engineers selected an E7018 electrode for the job.  Welding #8 to #14 reinforcing bar requires preheat of 200 degrees.  Job requirements include the ability to lay down on concrete to make welds in difficult locations.

Aluminum Fuel Cell

Aluminum Fuel Cell:

This aluminum fuel cell was fabricated using 1/8″ 6061 aluminum. It’s an auxiliary fuel cell that will mount to the back of a Triumph dual sport motorcycle. The client designed it and brought us a CAD drawing to work with. The pieces were pre-cut on a water jet which made it easy for us to weld. The tank has baffles inside to help keep the fuel from sloshing around. The baffles also serve as bracing for added strength. This project was Tig welded using 4043 filler. After welding was complete, we pressure tested the tank at 10psi. We were able to locate one pinhole. It was repaired and retested within 5 minutes. Project complete.

Pipe Welding

Pipe Welding:

Pipe welding can be demanding and rewarding. We were recently contracted to weld some 3″ and 4″ schedule 80 pipe for a major pipeline company. There were a total of four locations that needed to be completed in seven days. The client needed us to lay pipe to Baker tanks for a nitrogen purge that will pressurize the system to about 1500 psi. All welds were completed with SMAW using 1/8″ 6010 5P for the root and hot pass. We then capped with 3/32″ 7018 ATOM ARC rods.

Although there were many long days, we teamed with another welding contractor to complete the job on time.

Aluminum Welding

Aluminum Welding:

Aluminum welding is a treat when compared to carbon steel. Why? Because it weighs less than steel. That makes my back very happy.

This project took a couple of weeks. We fabricated 2 boxes, 2 pans, a cover and a push rod for a large pipeline company. The 6061 aluminum was 1/4″ thick. We used our new XR Aluma-Pro Mig gun from Miller. The push pull gun really made it easy to run those 30″ beads. We also used the Dynasty 350 with a 1/8th” tungsten. Anything smaller just balled up at 210 amps.

Cal 29 Sailboat Beam

Cal 29 Sailboat Beam:

Today I finished fabrication on a Cal 29 Sailboat Beam for a client in Vallejo, CA. The original beam was made of 3/16th” galvanized steel. After 30 plus years on the water, rust had eaten it away. The new beam was made of 316 Stainless Steel. Also 3/16th” thick, the new beam should hold up to the sea without a problem. This is a common problem among the Cal 29 Sailboat. If you need a beam fabricated for your boat, give us a call.

Trailer Modification

Trailer Modification:

We had a trailer modification job come in over the weekend. The client needed us to widen the front of the trailer so he could drive his quads on. It was widened 12″ on each side. We used 1/8th” diamond plate on the floor held up by 3″ channel. The structure of the trailer was untouched. We also covered the fenders with diamond plate to fill the gap that left the tires exposed.
