Robotic TIG welding suggestions

admin

The people I work for fabricate systems, vacuum lines, bubblers and ampules for the high tech industry. I have planted the idea of automating some of our welding and am in the need of some direction.  The largest parts (currently) are about 120 lbs, 12" in diameter by 16" tall. They need to be rotated around for all the weldments, so a positioner would have to be used. My max welding machine settings dont go over 170 amps DC. Wire feed needs to be an option.  Thanks for any help.Common sense in an uncommon degree is what the world calls wisdom.
Reply:Might want to look at jet line. They might have a auto cold feed tig system that will work for you or be able to make one.Could search internet for cold feed tig welders and see what comes up.How thick is the metal you are welding?  at 120lbs I see it being to thick for 170 amp tig welder. For automation you want to weld with in the 100% duty cycle range. So you don't have to worry about it over heating. At 170 amp you might only have a 40% duty cycle limit. 4 minutes to weld and 6 to cool down.you might only have 90amps at the 100% level. I have a customer the makes stainless pressure vessels. all the welders are 350 amp syncrowaves plus a 1000 amp sub arc. If the side walls are 1/2 inch you might want to look into sub arc.
