Replying to HELP with edges cracks

So my reno jibs have tons of edge cracks.11 to be precise with only 30 days of riding on them. One of these edge cracks is really bad and starting to lift and pull out but only slightly. The thing is I don't want this to continue with this edge cracks or any other ones. So i was thinking about welding the cracks then filing them down or seeing if a store could fixish them for me if it is possible. It would be awesome if some one could tell me some ways to help make shure my edges don't come out because frankly I have no idea what to do.

Thanks
