welding positioner -- copper bonding, welded threads .. pix
OK, I've been pestering everyone with technique questions recently, first with
how to bond copper tubing then with how to weld a threaded nut so the threads match another part. I thought I'd post some pictures of what I'm making. I'm working on passing the 7018 overhead welding test to get a Washington SMAW welding certificate, and to this end I'm making a welding positioner. Like most of my projects, it is made almost 100% from scrap materials, in this case pipe and some bits and pieces, plus an old sheet metal clamp-on base I dug out of a dumpster. The idea is to make a clamp which has no exposed threads to collect welding spatter. So I relieved the threads and glued copper tube pieces onto my clamping piece. The bit it threads into is where I had to weld on the coupler nut and not have the threads bind. It isn't finished yet, there are a few more pieces to make, but have a look: T-handle: http://www.tinyisland.com/images/temp/T-handle.jpg welding positioner: http://www.tinyisland.com/images/temp/In%20Progress.jpg GWE |

Nice work - looks like a table getting better tool sets.

"Grant Erwin" wrote in message ... The idea is to make a clamp which has no exposed threads to collect welding spatter. Neat project. At school we took a course on robotic welding. One of our projects was to make a fixture to hold parts together while the robot welded them together. I found it kind of interesting to figure out how to cover all the important parts to prevent splatter. Yours is a neat idea, definately something to keep in mind. Our sister company does the welding lines for panels so this isn't directly applicable to me, but I think there are many applications where it's advantagous to keep things covered up. BTW, those welds look good. Kind of refreshing to see some *nice* welds... Regards, Robin |

Nice.
If you need to make any more T-Handles, you might try silver brazing. I have made a few using brazing and they would meet your aestetics. Dan |

I love TIG...never need to worry about this spatter business. I can't
do it myself, go to a guy nearby, but the projects frequently have close clearances and moving parts, so having to grind the mess off the pieces would really suck. |
