fillet weld sizes
(OP)
what is a full strength weld? i have a dwg which this is required, the term seems pretty vaugue to me. I took it as being a full weld (not stitched). anyways does someone have a rule of thumb or table that has fillet weld sizes for different size plates?? im in canada so if possible to CWB standards

Don't worry about people stealing your ideas. If your ideas are any good, you'll have to ram them down people's throats.

FWSH Design Handbook for Calculating Fillet Weld Sizes
might give you what you look for.
Please note that fillet welds should be designed for stress in shear along the fillet, avoiding a moment developing across a one sided fillet weld.
Depending on the design, the requirement might also mean full penetration weld, with beveling of the transverse element (obviously depending on thickness) before welding the fillet on the whole thickness section.

As I recall, the AWS Structural Welding Code prohibits fillet welds that are as thick as the plate. Meanwhile, the tank codes require fillet welds that are as thick as the plate. The correct weld would be dependent upon the design code used, and need to come from whoever designed it.
"Full Strength" is not included in the AWS "Standard Welding Terms and Definitions".

The only thing that differs in Canada over our American counterparts is the quality of weld technician. This becomes apparent with testing, certification of welds and weld procedure approvals. Your local provincial Boiler Branch governs legislation of weld application, I strongly suggest you contact them for direction.
Also, a nice rule of thumb for weld sizes, measured at the throat of the weld, is not to exceed 75% plate thickness.

Once again, I encourage you to contact whoever did that drawing and find out what they want. If it's not obvious from the drawing whether it's a lap joint or butt weld, or what, the drawing is the problem, not your interpretation.

As JStephen said, these words are not defined and may mean different things to different people. It is good to ask the place where these were drafted.
To me, a full strength fillet weld is about 71% of plate thickness fillet weld, on both sides. But, there are caveats as always.
