Attachment 11601 Attachment 11602 OK, I see how I get better penetration, but this leaves ---- hanging down inside the pipe. this will be a bitch to grind out inside the actual parts, no? -The soldering station is being used to build a Megasquirt II v3.0 (fully loaded) -This project is entirely DIY... gotta get to work for now, -any criticism on the last weld pics, will be gratefully appreciated |

I know its hard to do anything more than make 50 spot welds when you're starting out. That being said as soon as you balls up and run a bead instead of ---- randomly hanging inside the weld you'll get a smooth bead running bearly on the inside of the pipe.
Like this but smaller. Attachment 11597 or this http://www.scielo.br/img/revistas/jb...1/a15fig03.gif Instead of a bevel groove, that one is a J groove. (Take an angle grinder and just grind into it.) Good illustration of a landing too. https://i207.photobucket.com/albums/.../photo-109.jpg Middle bead on that (bearly visible) Now that is proper penitration for this size pipe. Whatever gap and landing that was, do it again and run a bead instead of a tack weld - even if it completely collapses out the backside no harm done. If you do one that does collapse out the backside - travel faster! When you're welding slow processes like this one, as soon as the bead hits the width you want get moving & move fast/slow enough to maintain the width of the bead! Faster processes than this you just go LoL! |
