Video: Narrow Groove TIG

admin

Nice video of automated narrow groove TIG.   Some of the things to look for:Lead and lag cameras.Pulsed current sycronized with side to side weave, high pulse at weld toe.(Wire feed may also be synced for higher feed at toes, can't see it).http://www.carolinaenergysolutions.c...rooveweld.html
Reply:Wow.  3" deep.  That is pretty cool.
Reply:just what us welders need another robot to kick us out of a job :-( cool machineJason
Reply:Ahhhh Robots..Just what I expected..Call me anal but did anyone see the very end of the "root pass"There is a hole at the end of the weld.. Makes me wonder what the end of the weave looks like..They don't show that..Other than that?Pretty cool.....zap!Last edited by zapster; 08-07-2007 at 05:38 PM.I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Yea, the machine will never do the quality and consistency of a person.   If that were true, it would be the fault of the person that developed the weld parameters and programmed the machine, and the person that designed the joint, the one that machined the joint, and the one that fit it up.

Reply:Hmmmmm, Sorry Zap, you're not going to be able to manually weld that narrow groove.  These type of welds may consist of 50 or more weld passes on 6" thick, 12" I.D. SS pipe.  And if its a nuke repair type job, better to sit back in a comfy chair and remotely weld via the camera.The type of equipment shown in the video is orbital pipe welding.  It is generally remotely operated by a welder who can make adjustments to current, arc length, torch position, torch oscillation, wire position, wire feed speed, etc., during the weld.  It is like manual welding except the machine moves with much greater precision than possible by hand.  And the camera system gives visibility than a welding hood.  Other automated welding equipment is preprogrammed to make the entire weld with no adjustments.There are certainly situations where a machine weld is impractical and it is better to do it manually.  This may include a poor joint fit-up, where a welder can quickly adjust on the fly, and where it would take too much work to set up a machine to compensate for non-uniform conditions.  Machines, like humans, make better welds when all conditions like joint fit up, thickness, cleanliness, etc., are consistent.Last edited by pulser; 08-08-2007 at 12:52 PM.
