Testing your welds !!

[H-L-Smith]

This is a very nice thread and the photos and commentary make it crystal clear in terms of flat plates and T-joints. However, one if the things I've worried about is how to do a complex joint. I'm thinking both of the distortion issues and also the best sequence in terms of welding strength and perhaps grinding flat after each fillet or butt weld is completed?

An example in my mind is the joint where BR1, D1, U3, BR3 and D3 all meet.

I'd guess the only practical way to test a practice piece with similar joint would be to cut through it and see how it looks on the inside?
