HSS - End / Cap Plate Weld
HSS - End / Cap Plate Weld
(OP)
Is there a 'best' or most economical weld for a cap or end plate connection to an HSS member?
Assuming the cap plate will take load similar to this lifting lug problem:
http://www.eng-tips.com/viewthread.cfm?qid=256993
You could weld around the inside or outside using a groove weld or you could oversize the plate and provide a fillet weld. Is there one in particular that is better or ones that should be avoided?
I would preferably use the outside complete-joint penetration square (or V) groove weld with backing. Any issues with that?
Thanks

The cjp welds will, if im not mistaken, require a backer bar (not easily accomplished) or backgouging, which is not possible with a closed hss.
So with that, a pjp weld is probably a better way to go.
BUT, for 1/4" hss member thicknesses, it usually leaves you with an 1/8" maximum effective throat. see pg 8-55 for geometric limitations of the PJP BTC-P4.
If you can get away with it, a fillet weld will require no preparation that is usually required for CJP and PJP welds and will be the easiest solution.
