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 |
