Meed suggestions welding in tight spots

admin

This 1-inch half disc needs to be welded with 1/4" fillets all the way around. Only problem is my MIG gun will not fit inside once the last piece is placed.  I don't think a TIG torch will fit either.Any suggestions very welcome! Its 1-inch 316L stainless steel welded to same.Thanks,Gar Attached ImagesLincoln Electric, Power MIG 256Hypertherm Powermax 45 Miller Dynasty 280DXSmith O/A torchGenesis of a welding table
Reply:It looks like you either need to O/A or stick weld it.
Reply:Stick it.
Reply:Hello Gar, most all of the major gun manufacturers make close space/long taper tip and nozzle combinations. Most of the time these are used with skewed connection, fillet welds for plate type fit-ups, but they can really be applied anywhere where the space is limited. You just need to be mindful of your gas flow settings as the reduced orifice sizes do not need the higher flow rates and using too much gas will result in detrimental effects. I have included a link to some information from Miller to better explain this. Good luck and best regards, Allan http://www.millerwelds.com/resources...les-selection/aevald
Reply:....and after all those transverse beads are put down by whatever method.......that plate will be nicely bowed.Reverse bending prior to welding will help some, but not enough to keep it flat.This is a great example of a weldment that needs serious re-design before the fact,which of course-won't happen since this is a rush job.Blackbird
Reply:Hello again Gar, hopefully I will be able to attach a sketch to suggest a method for making those internal fillets along with the use of the long taper nozzle/contact tip combination. If you can position your part vertically and proceed to weld, as my sketch suggests, you stand a pretty good chance of getting the fillets in there as needed. You will however, need to take into consideration the shrinkage issues that the other poster mentioned and take some pretty drastic retention/preset measures while you are welding this. As you likely already know SS is notorious for extreme shrinkage/warpage issues.Sorry for the sizing issue, when I put things into paint they oftern come out too big and resizing screws them up.

Reply:If you have a rubber or silicon neck tig torch, which I recommend everyone have, bend it nearly straight, add a skinny nozzle, and stubby trimmed backcap, and lay it down on it's side and get in there from each end and meet in the middle. Of course welding one side complete meeting in the middke before tacking the other in place will take care of half the problem.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.

Reply:Pencil torch or new ck flex head torch
Reply:Thanks for all the input, I really appreaciate it. It looks like I will be stick welding the last inside fillet. To deal with the warpage, I was considering sandwiching a 1-2-inch piece of aluminum between two base plates and clamp it tight. I may also run two beads accross the back sides to pre-bow...?

Reply:I constantly have to get in tight places just like that so I use this method with GREAT results...http://weldingweb.com/vbb/showthread.php...hlight=BendingIt works and that's that!...zap!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:Zap,When I saw that there was a post by "Zap" I thought to myself, before even reading the post, "now I have a solution."  That is awesome Zap!  That is just the kinda stuff I was hoping to learn about.  It just so happens I have a 1/2" thick block of copper as well.  I am in debt to ya brother!!GarLincoln Electric, Power MIG 256Hypertherm Powermax 45 Miller Dynasty 280DXSmith O/A torchGenesis of a welding table

Reply:Originally Posted by Fnord5But, wouldn't it get better results if you clamped the tungsten with the ground, and uses the TIG torch to heat up a section with the arc, and bend it that way?
Reply:Originally Posted by Fnord5OK.. I am a noobs noob when it comes to welding in general, and even worse with TIG. But, wouldn't it get better results if you clamped the tungsten with the ground, and uses the TIG torch to heat up a section with the arc, and bend it that way? I just don't see how that tiny bend makes much of a difference.But what do I know?
Reply:Originally Posted by joshuabardwellSeems to me like too much bend would take the tip out of the argon flow.

Reply:Start by completely welding one out before the 2nd piece goes into place.  Will save ya half the trouble.  Other than that, I'm going to drink some more coffee.-AaronJet 17.5" Drill Press1942 South Bend 16x84 Lathe1980s Miller 320A / BP --- 2013 Power Mig 2562012 Jet 7x12 Horizontal BandsawVictor O/A Setup

Reply:Since I could not obtain access to a TIG machine that could do this using Zap's great idea, I had to make due with what I could beg/ borrow.  So far so good!Gar. Attached ImagesLincoln Electric, Power MIG 256Hypertherm Powermax 45 Miller Dynasty 280DXSmith O/A torchGenesis of a welding table
