here is after hours project i did
a 750 ltr fuel tank of a kenworth the wanted it made into a fuel and hyd oil tank he wanted aleast 200Lt's of oil so this what be got a tank that now holds 500lts of fuel and 250 of oil
I did this one at work as my tig at home dosn't have a foot pedal and a pedal is very handy doing a job like this
first job was to carefully cut down the weld to get the tank end out in 1 piece the pics aren't the best as i used my phone to take them
heres what i used to cut the weld out
here it is after the end is cut out
pretty dirty in side so its out for a steam clean to get rid of dirt and any fuel thats left in side
after it was steam cleaned i washed the in side out with some aluminum cleaning acid
once that was done I had to make up a template for the piece to seal of the tank then cut the
section put a couple of stress bens init to stop it moving with the weight of the fuel and oil then trail fit it
once i was happy with how it all fitted it was time to put my head inside the tank for an hour and tig it up
then presure test it before putting the end back in
one the inside was done I put the end back init and welded the fittings on
gave it back to the owner collected a nice tax free payment he was happy so was i
