Advice for strengthening a steel beam web for shear?
(OP)
I have a steel I-beam whose shear capacity is not enough.
I can only think of making a “sandwich” web by welding two plate each side. Any good advice?

From my experience, other than adding plates along the web, there is not really much that you can do.

I worked on a project before in which webs were strengthen by welding threaded rods (in a similar way to the way shear connectors are welded) and bolting a plate to the web. It worked, but it was very time consuming

It's also unusual for any beam connection to develop the full shear capacity of the beam.

As JedClampett pointed out, pay additional attention to the connection support detail, its capacity and how the load gets into it. Don't stop the web doubler short of the connection!
