Gas Tungsten Arc Welding is the Proper name for TIG welding. Well it may be the proper name, but it takes too long to say… and since hardly anyone calls it Gas Tungsten Arc Welding and most everyone still refers to it as TIG Welding, That’s what I call it too.
Post weld heat treatment is the work done after something has been welded. It uses new heat to improve old welding work. Post weld heat treatment can eliminate brittleness that has evolved on metal pipes over time, or it can be used to strengthen metal that has been weakened by lots of use.
If we get into the details of the kinds of tests for the pipe welding, we may get lost in it. Therefore, it is better to take an outline view of what is it all about? There are hundreds of Read more tests but two of them are more dominant. They are 2″ and 6″ schedule 80 pipes in the 6g position. The sad part is that these two joints need to be welded in various ways.
It is good news because it means we can pull ourselves out of our current economic troubles by simply producing natural gas and oil from our own reserves. We can easily create a million jobs.
U.S.manufacturing has declined, but the U.S. remains the biggest manufacturing company in the world, with about 20% of all world manufacturing. Soon, the U.S. will be the largest producer of oil.
For open butt root passes, the thing that will kill a test is slipping and shooting wire thru the back side. Some test inspectors will fail your test for that…and all it takes is one slip, so being rock steady is key.
All kinds of things get towed including welding rigs. Let’s say it’s a DUI and the rig is impounded. The system charges so much for that impounded rig, it doesn’t take long and the welder throws up his hands. The rig goes to lien sale. If you have your ear in the right spot, you can pick up an amazing deal. This is also a great way to buy a good truck or car.
The way certifications are numbered may suggest to you that you should get your structural certificates first, then progress to pipe. That is exactly how it is intended. The problem is, by the time you get through structural welding school, you’re out of dimes, time, and you’re looking for a sign which says, “Welder Wanted.” So there you go, pulling the old MIG trigger for $12 an hour. Don’t do it. Skip structural welding and teach yourself 6G at home. When you certify 6G, you automatically are given all the lower certifications – so why screw around?
