How do I weld my bung properly?
|It is a good practice to apply several small, equally spaced tacks to minimize the potential for distortion. The bung should also be preheated and the weld should be kept small to reduce natural weld shrinkage.
The cap won't fit after welding my bung. How do I fix this?
|Minor distortion of the bung from improper welding can often be addressed by applying a small amount of fine grit lapping compound to the cap threads and turning the cap back and forth in the bung to resize the threads. Do not force the process, be patient and thoroughly clean both sets of threads after the desired fit is achieved.
