Man, I wish I would have caught this thread in the beginning. So much ******** in here.
A few thoughts from the perspective of a Certified Welding Inspector that deals with weld quality on a daily basis:
A few thoughts from the perspective of a Certified Welding Inspector that deals with weld quality on a daily basis:
- The only GMAW process that shouldn't have RT performed on it is a short-circuiting method due to metal deposition process.
- SMAW is, and always will be, a relevant process to learn simply due to the industrial applications.
- GTAW is our preferred method of putting a root into any process piping, with FCAW hot/cap passes.
- Anyone that thinks RT is easy to get welds past should meet my friend called Phased Array.....
RMD is where the money is currently, we had a hell of a time finding qualified RMD welders for the last construction project. Or if you are a jam-up GTAW welder, you can command a premium. Especially if you can scratch start without tons of tungsten inclusions.They emphasize stick welding because that is where the REAL money is at. Pipeline, ship building,and equipment repair.
[/quote]This has already been discussed, but see above anyway.Some custom fab work will use MIG but not anything that requires x ray inspection quality welds. Inspection standard welds is what schools teach and right now no MIG process is rated to produce inspection quality welds. Once again, they are teaching what will make the student money not just generally teaching them to weld.
We have started using more RMD lately, it has some pretty epic metal deposition rates. Depending on what code they are using for acceptance standards, I doubt they are utilizing UT on RMD. Short-circuiting methods are generally examined by either UT Shearwave or UT Phased Array. GMAW root with SMAW fill? Rarely see that, generally its GTAW root with SMAW fill. If running GMAW, its usually 100% GMAW (hardwire or flux core).Quite often they are using a Lincoln SST or a Miller RMD for the root pass on the gathering lines for some of the Sagd plants in northern Alberta. Then they are then using Fcaw (flux core with shielding gas) for the fill and cap. All 100% RT.
I did 2 job tests today for a fab shop. One was Smaw- 6010 root 7018 fill & cap- 6g. The other was Gmaw root, Smaw fill and cap (7018).
You obviously haven't been around tank construction much in recent yeas. I would suggest instead of maintaining a condescending attitude towards welding methods taught you learn what industries use what , where, and how. I do agree that more advanced methods need to be taught more, but even if you went to school to run pulsed/computer controlled/push a button and make a weld method, you'll still have to know how to run the "1940 weld tanks together" methods.The only people that I know of that routinely use stick are pipe welders and I'm way too old to be working in a refinery. In Germany they have pulse MIG and pulse Stick and a lot of advanced welding technology in their schools. Here in American we're teaching students skills that they needed in 1940 to weld tanks together. Another reason we're falling behind.
