Depends on what/how the welds are lumpy. Many feel that the "stack of dimes" weld bead is the perfect weld yet the bead is quite lumpy. Just that the lumps are specifically shaped. Some companies do some after welding filing/grinding of the bead and remove any lumps. Neither method says anything about weld penetration, undercutting or tube distortions though. Judging a weld from a photo of the joint's outsides is lacking in complete info and thus is only partially valid. Andy
