Appropriate weld for L4"x4"x1/4" welded at 45degree angle.
Appropriate weld for L4"x4"x1/4" welded at 45degree angle.
(OP)
What is the appropriate weld to specify for two L4"x4"x1/4" coming together at a 45degree angle? the angels have both their flat faces touching. Is it a square weld or a grove weld with surface prep on one or both of the two angles?

how are the angle iron actually touching each other? The interior connections on small parts like two 45 degree angle iron parts at 45 joint can be very, very difficult to weld and clean up properly in the little confined spaces - or they can be easily accessible and dirt-cheap to assemble.
how "clean" a joint do you need? Do you care if it looks ugly?
How many joints?
Field or shop welds, or a combination?
How many assemblies?
how good a team of fitters 9the people cutting the steel) and how many welders?
How well trained are they?
Are you going to make a jig-and-fixture to repeat this many times?
Same pieces all the time, or is each piece a unique assembly one-of-a-kind?
Are you going to be doing this overseas with Chinese welders, or locally by yourself?
are the angle iron and assemblies "designed" professionally or did you just assume a 4x4x1/4 is "big enough"?
What are the loads involved on this joint, and are they static, or vibrating and randomly distributed so fatigue is a problem?

And, as racookpe1978 said, aesthetics too.
Without a sketch or picture I am likely envisioning the joint completely wrong, but sometime a lap joint is acceptable, and can sometimes be done with square cut end preps and fillet welds.
