All Around or Just a Groove (Cylinders)

Date 12-02-2015 15:33

Can't quite choose what to do:

When a weld is made on a cylinder, is it required to note "All Around"...or can one leave it empty under the impression that indeed it will be welded 'all around' as there's no length?

I hope the picture helps!

AWS A2.4:2012 page 19 6.10.2 Circumferential Welds. ....do not require the weld-all-around symbol to specify a continuous weld [see Figure 8(E)].

The same goes for an object intersected by a plane? Ex. Welding a pop can/Square tube to a table? Or something oval....

"Welds extending around circumferential joints with no abrupt change in direction (e.g. pipe, round bar) are excluded....."
Please note the use of a specified standard and not of an opinion.

Agreed, it was the matter of 'change in plane' from 6.10.1 helps as the object in question here is a oval put through the wall of a rather large cylinder. Thanks

I think the more information the better, what would it hurt to leave the "all around" indicator on there? Also, either your picture is upside down, or you are indicating the weld is to be made on the inside of the cylinder. Is this a test?

You win! haha, other side is indeed not the correct side. Consider it a 'close eye' challenge. Cheers!
