Weld symbols for box section.

[clamberer]

Hi All,
Not sure if this is the best sub forum for this but I couldn't see a more relevant one.

I am having to create a number of technical drawings of welded steel box section assemblies.

My question is: with mitre and butt joints in steel box section, what weld symbols would you want/expect to see?

After all, on a mitre joint you will be performing a fillet weld on the inside of the corner, a corner weld on the outside and butt welds on the sides. Would it be best to separately annotate all three types, or would it be acceptable/good practice to just put the symbol for an all-round v-groove butt weld?

Similarly on a T joint, you have both fillet and butt, plus the radiused corners of the box effectively give a groove but it is not a prepped one..

Thanks in advance

These are 3 different joints with 3 different symbols . I refere to these type of drawings most days. It's a lot easier and perfectly acceptable to produce 2 x 2d drawings. Look up all the symbols and process/dimension codes on the net understand fully what they mean and put them into your drawing. Studie them carefully though as a simple erra like putting the symbol on the wrong side of the line could be a disaster.
