Some Tig

admin

I welded a bunch of couplings to plate for a customer.http://weldingweb.com/vbb/showthread.php?t=26837 The customer took them to a machine shop, and the machine shop called me and asked me to do some couplings for them.  I can't show the piece, but its 7/8" thick, about 6" wide and forty something long.  These are 3/8" couplings.  The print called for a 1/8" fillet.  It came out 3/16" with  no undercutting.   I clamped them to the positioner and worked around the length.  Each piece gets 3 or 4 of these in different places.  Holes are there and a pilot tool to hold the couplings in place.  I tigged the first 24 because I didn't have time to build a jig,  There are a total of 36 bars.  The couplings come already cleaned up.  Total 132 couplings.1/16"  Er70S-6  1/16" tungsten couldn't take the heat, so went to 3/32 red or gold.  Arcmaster 185, max 160 amps.  I used most of em.Start Stop.I am going to see if they have a scrap one I can try pulsed spray on.

Reply:Nice David.Thanks for reminding me on how bad I need a positionerWith that P sparay you think it will be much faster? weld it like you own it
Reply:Once I build a jig and use pulsed spray, I should be able to knock these out in a day or less.  It took at least 1/2 hour each bar using tig.  They want a price per piece.  If I bid it with tig, I won't get the job.  If I build a jig and use pulsed spray, I'll make some good $s.These machined parts are a work of art what ever they are.Tig is pretty, but .....   $s countthey dropped off 12 bars, there are 36 total, I am going to do the rest of the job when all the pieces are here.  If I turn my positioner vertical and use a counter weight, it should be easy.   Its gonna look like an airplane propeller.  David  Last edited by David R; 01-18-2009 at 08:31 AM.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:Sure looks like that positioner turned into a nice little investment for you. Might take a little practice with the spray to weld the heavey plate and lite coupler with out under cut. Keep us up to date with this and the cell tower project.
