I hate the look of ugly welds and it's a huge PITA to grind 'm out and start over Attached image(s)

Could it be impurities on the surface, and not so much your welding technique?
If this happens and you are concerned with the appearance and/or ultimate strength I would recommend having a die grinder handy with a carbide burr to grind out the offending section and reweld. Going over the top just leaves the impurities inside, often in the form of a big gas pocket. |
