It is a risk Patrick but, I think what Jerry is doing with the holes is an old race car chassis builder technique that allows air to escape from a tube being welded that is closed on both ends without damaging the weld joint or the welder.

As the welding process proceeds, the air in the tube is being heated and absent the small air bleed holes the heated and expanding air in the tube would blow out a chunk of molten weld material from the weld joint.
