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.

 

Cell Phone Tower Modification

I received a call I was hoping to receive, this company needed a certified welder to modify a cell tower here in Fair Oaks, CA.  I believe this is a great fit for my company and am hoping to be able to take care of all the cell tower modifications for this company.

There are several critical elements to modifying a Cell Tower.  Safety is of utmost concern.  The threat that fire is to the cables is always in the front of our mind.  It is critical there be  a fire watch and we had to provide a 500 gallon water trailer on site.  Next the galvanizing must be removed at every weld location.

The galvanizing on this pole was approximately 1/16″ thick.  We had to grind approximately 400 lineal inches by 2″ wide on this pole for the plates that needed to be welded on.

Two of the six gussets we welded on.

The vertical plate shown here with the holes in it is typical of 3 plates on this pole.  They are 10′ tall by 9″ wide.  We drilled 17 1-1/4″ holes in each then mounted them and drilled thru the tower at each location.   Also you can see how close the cables are to the weld locations.
