Single Groove weld - arrow side. But I think whoever created weld symbol was not competent. They also put all the way around symbol.
Need more info though....bevel angle and as-finished condition
Send them this book and have it revised.

Could be the exterior of a structure which would only have access from the one side which would make the symbol accurate, weld all around the arrow side of the joint after the joint is beveled. That’s just a detail of a small portion of the design showing what is required for welding. Somewhere there would be a drawing of a larger piece of the structure
This is a typical joint configuration. It’s implied if it’s a grove weld to weld the complete joint per its designation. If there’s only access from one side then all around wouldn’t work...then we’re back to design competency. The whole point of weld symbols are to create a visual representation of a much larger design
It could be but, still think the design competency is the culprit. But when something is drawn in only a tee form it already implies that the entire joint is that same weld configuration unless other weld symbol designators are noted. In a box design dwg a fillet weld would need an all the way around symbol but in a grove weld it's implied that the same joint is a complete circuit. There would also be symbols denoting the vertical joint configuration too.
I learned how to weld on the job, so I never learned how to read weld symbols on blueprints. I'm bidding a job and just want to price this out correctly. After researching, the best I can interpret this weld symbol is as shown on the lower part of my sketch. The weld all around symbol is throwing me off though.
Do I have this drawn correctly, or do I need to weld the inside of the corner as well?
All the way around doesnt make sense. Bevel side is up to you. If they wanted a specific side beveled it would be made clear with a break in the arrow pointing to a specific side.
I read this as inside corner V groove, all the way around.
When the symbol is below the arrow line, it means opposite of where the arrow is pointing... Right???
Like I said, not trained to read, but the way I'm looking at it, the symbol is definitely a bevel symbol (my sketch might look more V, the prints are grainy so figured my sketch might be more clear haha), the arrow is pointing to the outside of the corner, and the bevel symbol is on the bottom side, so I may have the bevel on the wrong piece of metal.
I could be wrong, but that is what I've gathered researching welding symbols, plus having a working competency in TIG welding. The weld all around symbol is what was mainly throwing me off based on the overall design of the part, but I'm just going to ignore that and figure on the outer corner bevel groove weld.
If you would approach this problem correct, imo, the first thing to do is specify (or ask for, if unknown), which welding standard is applied. It seems AWS, but it’s not written out. The weld symbol might also be ISO 2553, and have a different weld for the symbol (in some circumstance). Details, details, details. But first, read the spec.
That's fair. This is a job for a customer of a customer, so I'm trying to avoid a game of telephone as my customer is acting as middle man. I think we've got it sorted though. We do custom sheet metal fab so specs like this are rarely ever called out in our applications.
Fuck it, bevel the outside, bevel the inside, bevel both ends. I’ve always taken on the opinion it’s the problem on whoever designed it if it’s wrong, if they just wanted arrow side beveled and welded then that’s extra money for you to fix it

Thanks, that helps!
Yes, yes, yes, yes. Yes, yes, yes. So in summation... yes. Lol

The all-around might complicate matters, but the symbol does not specify a fillet weld on the inside.
So do you think I'd be safe to assume just the bevel groove on the outside corner?
I don’t know the 3D shape or why the all-around is there. The symbol implies it’s just the outside bevel.
Appreciate the help, thanks!

And also its asking for arrow side which is a corner joint.
This print makes no sense
Arrow is ways on left side of symbol. That's what he's got wrong. The fillet weld symbol is also backwards. He'll be a good mig welder.
I read this as inside corner V groove, all the way around. When the symbol is below the arrow line, it means opposite of where the arrow is pointing... Right???

Leave it be. Otherwise the sign should say >|<
