Seal Welds and Intermittent Welds

[Boiler106]

I am reinforcing a column in a corrosive environment using AISC. The column is a PEMB built-up column with 3/8" flanges that i am welding an HSS member to along its length. I would like to limit distortion of the flanges using an intermittent flare bevel weld and then follow up with a seal weld along the length.

How would i show this weld symbol and does this make sense?

I would be reluctant to use intermittent welding in a corrosive environment.

Put "seal weld remainder" in the weld tail. The PEMB column is probably already only seal welded and generally they aren't coated for use in corrosive environments, so I'd doubt this is the first thing to go, but for corrosive environments I'd also reconsider the use of HSS

yes, hence the seal weld

thanks this is helpful. the hss will be sealed. fortunately, its not in a highly corrosive environment. just something that has happened over a long period of time.

Sorry, I should have said the PEMB is only stitched, not only sealed. You're on the right track then, the intermittent weld with seal welds also reduces weld inspeciton vs a full length weld
