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.

City of Tracy – Water Tower

City of Tracy – Water Tower

The City of Tracy Water Tower was built in 1928.  Located in front of city hall, it now serves as an historical structure.  In an effort to make it last many more years, NorCal Welding was contracted to perform some structural reinforcement.  Welding was carried out as per engineer specifications in an effort to reinforce the plates at the base of the tower.

When we arrived, the temperature outside was about 34 degrees.  The photos below show various stages of the job to include preheating the 1-1/2″ plate to approx 250 degrees, welding and inspection by the city engineer and welding inspector.

Public Works

Public Works:

This public works job for the San Jose Police Department was just completed. We were contracted to fabricate and install new secure key lock boxes for all pedestrian gates. All metal was .125 mild steel plate. There were four different styles due to the different gate styles. Fabrication was done in the shop in Tracy, CA. Onsite welding was completed in two days.

We want to thank everyone at the San Jose Police Department and Santa Clara County Sheriff’s Office for all your help. Background checks and fingerprinting was pleasant and painless. Thanks again.

HVAC Reinforcement

HVAC Reinforcement:

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.

Structural Steel

Structural Steel:

This structural steel job was just finished in San Pablo, CA. We were called to the UPS facility to weld over 3500 pieces of steel by the October 31st deadline. Our team of 7 structural welders and 2 apprentice welders worked 10 hour days for 6 weeks to achieve this goal. Working in boom lifts and scissor lifts our team installed over 375 knee braces and welded them in place with .072 NR-232 wire. Some 7018 was used for other tasks including tacking down the bar grating on the second level.

UPS is a leading edge company. All the automated conveyer systems that sort, track and load packages is impressive.

D1.8 Certified Welding

D1.8 Certified Welding:

NorCal Welding provides D1.8 Certified Welding. We have several experienced welders that have passed the welder qualification test for AWS D1.8. This is the seismic supplement to AWS D1.1. While many believe D1.8 is strictly a certification for filler, there are also requirements for welder qualification. Below are a few photos of our D1.8 welders welding the seismic joints for the new VA building in Martinez, CA.
