Safety Railing

Safety Railing:

We just completed this safety railing at the Defense Distribution Depot in Tracy, CA.  It was fabricated in our shop and transported to the job site for installation.  The specifications on the railing called for 2″ x 2″ x .250 steel.  The wire mesh was sheared to fit and made it easier to weld into place.  Once the field welding and installation was complete it was painted a bright safety yellow by Tarnowski Painting.

Woodside High School

Woodside High School:

We just completed a job at Woodside High School in Woodside, CA.  The school was built in 1958 so we replaced some old gas lines on the roofs of the buildings.  With new safety valves installed, we welded 3″ pipe over the course of three days.  These gas lines go from one building to another so we installed special flex-lines to accommodate for seismic activity and the shifting of individual buildings.  Over the three days, our guys worked through the hot sun, some pouring rain and into the night to get the job done.

Moment Frames

Moment Frames:

Moment frames are a critical part of structural welding.  We teamed up with Merjil Steel Fabrication, Inc. to build a new CarMax in San Jose, CA.  While most of the D1.1 welding was completed by Merjil Steel, NorCal Welding was tasked with the critical D1.8 full penetration welding of all moment frames.  Our team of four used NR-232 .072 filler.  All welds underwent mag testing and ultrasonic testing.

Gas Pipe Welding

Gas Pipe Welding:

This gas pipe welding job was just completed for the Unites States Coast Guard at USCG Base Alameda.  NorCal Welding was contracted to install 300′ of new gas line.  The black pipe was 4″ schedule 40.

Pipe Welding

Pipe Welding:

This 18″ pipe welding job was just completed in Stockton, CA.  A section of pipe needed to be replaced for a pump station on a levee.  G&N Construction exposed the pipe for us and assisted with placing the new pipe in place.  After everything was in place our certified welder got to work.  6010 root and 7018 cover.

Soft Story Retrofit

Soft Story Retrofit:

This soft story retrofit was just completed in Piedmont, CA.  While the contractor rebuilds the structure, current codes require moment frames to be erected in the basement.  Based on approved engineering plans, we fabricated two moment frames onsite.  Beam sizes were W8x28 and W6x15.  All steel was moved by hand into the basement through a small window just large enough to crawl through.  All welding was done by SMAW using 5/32″ 7018 electrodes.

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.

Oil Tanks

Oil Tanks:

Dynamic Generator Service, Inc needed a couple of custom oil tanks fabricated for their F550 service truck.  We used 10ga steel to fabricated a couple of 112 gallon tanks.  Customer provided bungs were welded on. The tanks were pressure tested proving that no leaks existed.  The tanks were then painted and installed on the truck.

Moment Frame Retrofit

Moment Frame Retrofit:

This moment frame was just fabricated and installed in San Francisco, CA.  The seismic retrofit was required by the city as part of an upgrade during the home owner’s renovations.  The beam was 800lbs and lifted into place by five men.  The column was 11 feet long at a height of 96 inches.

Moment Frames can be welded on the job site or in the shop.  NorCal Welding had the steel delivered to this job site so we could do the welding on site.  Our welders are D1.8 certified for seismic retrofit welding.

ADA Handrail

ADA Handrail:

This ADA Handrail was fabricated for the City of Oakland.  It’s for the new ramp at the Manzanita Recreation Center on 22nd Ave.  Due to the heavy rains we’ve been having, most of this handrail was fabricated and welded at our shop in Tracy, CA.  Today we had great weather for the install.  This ADA Compliant Handrail was fabricated with 1.66OD steel pipe.  It was 88 lineal feet and coated with a black oil based paint by Rustolium.
