RE: Welding HSS

[Subject Prev][Subject Next][Thread Prev][Thread Next]

As of AWS D1.1:2006, flare vee groove welds are prequalified, within limits, of course. They were not prequalified in 2004 and prior versions.

David,

If I understand the layout here, you would be calling out a Flare-V Groove weld on each side which is certainly doable but would require a welding procedure (WPS) that is qualified by testing since I do not believe none are prequalified.  If this is a beam, the horizontal shear stresses should be low at the mid point so that should not be much of a problem.

Welding HSS

 

 

 




How well can two square HSS be welded side-by-side?  For example, can two 6x4 tubes be welded with longitudinal welds to create an overall 6x8 tube?  How detrimental are the rounded edges in this situation?
