Steering Coulmn Breakage (when pressing in new pin)

Question? I took my steering column out to replace the seal at the firewall. To put the new seal on, i had to have the pin that goes in the end of the shaft removed, i went to Jerry Ulm dodge and got the kit for the coupler (with a new pin) I do not have a press so i had a local shop press it out. we put the new seal on, but when the owner pressed the new pin in, it broke part of the column. I had a buddy hit w/ a Mig but it was not a full weld (I had to do some grinding on it to get to were I thought it was ok) The guy at the shop said "If it can't go anywhere, it'll be ok" What do you Pros think? Power steering car....... i have put some miles on it but, I wonder.......It didn't really break the end of the column, just blew out a little bit of it.
