These are not that difficult... The pipe should slip inside the flex joint a little distance.Mojo88 wrote:Or should I be trying to get all four numbers fused together? It seems like a daunting task and I am a relative noob at TIG.
You then just use enough filler to basically weld the whole 'stack' together and create a nice bead that locks it all together. 2.4mm filler tends to be a nice size for this to wet it all out and fill the spaces.
You probably won't be able to get into the 'root' of the connection completely as the gap remains too big there, but in the end you should aim to have the weld bead fully attached to the outer 'ring' in the end.
Just put about 4 to 8 tacks around the join to keep it all in place, get comfortable, purge the back and start welding in sections. Let it cool after each 1/8 section so you don't overheat the part.
