In the end corner of a weld symbol a vessel drawing has 7018. I guess 70 signifies tensile strength of 70 ksi for the weld rod material. What does 18 specify?

RE: weld rod
The "1" relates to positon. In this case "all". 8 relates to the flux.
See any welding supplier for some free guides.
RE: weld rod
Cellulosic: xx10 and xx11
Rutil: xx12, xx13 and xx14
Basic: xx15, xx16, xx18
etc..
More over DEANC is right about the "1".
"1" means you can weld on all position, becarful it is not right all the time.
But if you have "2" in lieu of "1", that means you can weld only on flat position and horizontal fillet.
For your application the electrode E7018 is a real standard as basic eletrode.
RE: weld rod
As stated above I would get the all the literature and information from your consumables supplier

try Lincoln: just read the low hydd. specs and surprinsingly you will learn a lot.

RE: weld rod
A low-hydrogen electrode for use in all positions on low, medium and high-carbon steels. 70,000 PSI tensile strength. Ideal for out-of-position welding and tacking. Runs on AC or DCEP (reverse) polarity. Not recommended for low-voltage AC welders.
7018 AC Welding Electrodes
Same as above, but specially formulated to operate with small 208/230 volt AC welders.
