Will try to upload some more pics when I can. Here's a weld on 3/8" .035 4130 aircraft tube welded to a 3/4" square .049 tube. Not perfect but as it doesn't need to be, I am rushed and no full welds. As it is this was overkill. Students do the fitup so occassionally I have up to 1/8" gaps to fill. Weld measured around 3/32....too fat I know but I only TIG this much once a year or so.
