Which electrode for Universal Beam?
Hello all
I am building a lean-to on the machinery shed. It will measure 10m x 5m. Skillion roof - 4.8 m on the "high" side, 3.6m on the "low"side.
I got hold of some 200UB25 at a clearing sale, so I'll be using that for the columns as well as the rafters.
The columns will be concreted in the ground like a fencepost - holes 1200mm deep x 600mm diameter.
The rafters I was going to mitre cut (at the right angle) and weld straight to the columns - no bolts or haunch plates to bother about.
Now, what rods would be best? WIA 12p's are my "go to" rods for most farm applications but doing a google search - mostly on U.S. forums and sites - they say 6010 for a root weld and 7018 over the top of that.
Is this correct? Sounds a bit over the top. I mean it is not welding high tensile or pressure vessels. It is only mild steel, and not particularly thick - 7.8mm flange thickness and 5.8mm web thickness.
Regards
Graeme
