TIG Week #1 pictures

admin

I started TIG today for the 1st time in class and here are some pictures of my practice welds. We only did horizonrtal. What can I improve? Is there anything good about it?The middle weld was already done. I am practicing on practice plates.http://imgur.com/eYZQTcAhttp://imgur.com/F9LjOhchttp://imgur.com/EXlaqGbhttp://imgur.com/LA6ZcgFhttp://imgur.com/xOdYE3Uhttp://imgur.com/Lkah4KKhttp://imgur.com/DWnvzsRhttp://imgur.com/DkA4tRHhttp://imgur.com/XKAv9Lphttp://imgur.com/YtAsNyGLast edited by WannaBeWelder; 03-18-2014 at 11:32 PM.
Reply:Coming from a novice welder, feed speed of filler, and travel speed are the two biggest things that trick me up. I can make a really nice looking weld, but I know my speed is slow due to the "heat" showing through the steel. That center weld looks like a combo of too slow travel speed, and too mich filler. Unless that was intentional. From all that Ive read on what tig welds should look like after theyre done, they should have a uniform width, small heat affected zone, and relatively flat. The closer you can keep the tungsten to the work, the more localized the heat stays (so Im told)Of all the things Ive done, Tig is definitely a challenge. Being a musician, I feel its has helped me a lot with the many things going on, pedal, torch, and filler. Youll get there, keep at it.And if any of what I have said is wrong, please feel free to correct me.

Reply:Yea sorry just got home and missed the bit about the center weld already there.It would be great if you could get your own "new" piece of metal to practice on.
Reply:Picts are a bit blurry, so it's hard to tell a lot of details. Knowing your material thickness, amps, filler size etc will help as well. It can help if you can post individual beads vs one big mass as well. This makes it easier to point out individual problems with individual beads vs trying to point out beads lost in the middle of a plate. I know that may not always be possible in class.Biggest thing that I can see with these poor picts is lack of consistency. Your dips don't look even, but that's not a surprise. That comes with practice. One thing I do note is there is a reddish tinge in the picts in the top right. That is often a sign you dipped the tungsten and then didn't regrind. Also you want to get all that crud off the plate with a brush after you contaminate the tungsten as well or you'll just suck all that contamination into all your welds..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan

Reply:I kind of thought that might be the case as far as filler. It's not at all unusual to have guys do beads with no filler at 1st to get a feel for things so they understand the torch and controls. 160amps is about what I set machines to when having guys start out doing beads with no filler on 1/8" plate so they have enough amps to see what going too hot can do. I turn it down a bit when they start doing beads with filler so they have a bit less extra amps at the top end and a bit more control.Oh see if you can't swipe a piece of filler if you don't already have some at the house next class. This will let you sit and watch TV and work on feeding filler with your off hand..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.
