Welding to I-Beam

[darryl3]

Newbie Question I cant find anywhere here.

Looking to weld some angle to the flat face of an I-beam. The load would be minimual 100#, and little moment on the beam, but some concerns over code, due to the fact that the I-beam supports the roof. Any restrictions on welding to structural beam?

Thanks,

The restriction that I always remember is never to weld across the face of the I-beam, due to the risk of forming cracks at a high stress point. If you run a bead on the edge of the face, that is less likely to form a crack, minimizes the stress raiser.

Obviously many things are just clamped to the I-beam. An angle iron could have one clamp on each side, especially if the weight involved is not a lot.
