SWPS B2.1-22-015 is the Standard Welding Procedure Specification (SWPS) for Gas Tungsten Arc Welding of Aluminum (M/P-22 to M/P-22), 18 through 10 Gauge, ER4043 or R4043, in the As-Welded Condition, with or without Backing. 0000079828 00000 n I like to cut an X in the tape using a pocket knife so that it can open up under pressure. An eddy current test is a non-destructive test (NDT) that uses the principle of electromagnetism to detect flaws in metal objects. ), 2) SMAW using other than F-3 Electrodes (E7018, E308-16, etc. 0000080454 00000 n A Charpy impact test is a welding test used to determine the toughness of a welded joint. The weld itself can be tested or the surrounding area may be tested if there is any doubt about the quality of the weld. Im finishing up my schooling a the Hobart Institute of Welding Technology and will be taking the UA-21, UA-41, and possibly the UA-15 pipe tests. like around 70-80 amps and sometimes as low as 65 depending on gap and edge prep.For the second pass, I use a 1/8" rod and a bit more amperage .close to 100. Tig Welding Tips - UA41 6g Pipe Welding Test (re-uploaded) Some of the most common techniques include: Welding is a process that can create some of the strongest bonds in metalworking.

Learn a Union Trade as you Transition out of the Military - UA VIP NDT can also be used to inspect welds for quality control purposes. Non-Destructive Testing, or NDT, is a process of inspecting and evaluating a weld without causing damage. Copyright 2023 !www.materialwelding.com! Would you prefer to share this page with others by linking to it? NDT allows products and components to be inspected without causing damage, which means they can be reused or recycled.

UA 41 is carbon steel 2" schedule 80 open root TIG root pass and fill. That is why we need a welding test. The energy required to make the fracture is called the Charpy V-notch toughness or energy. I'm just starting out so (you're right) I haven't taken many test (only 40 or so all being hodgpog of root/face bends, side bends, macroetch, dye pen, and x-ray) SO FAR! It tends to resemble a keyhole of an old fashion door.The keyhole is key indicator of your amperage and if it gets too big, that means you need to turn the amperage down, feed more rod, feed rod more oftenetc.Cutting the tacks out is not always permitted by test inspectors so you should probably ask about that before you do it.and also, sometimes a grinder is not allowed after the tacks are feathered.again, these are things you want to ask about if you are in doubt.A 2 inch schedule 80 pipe has a fairly small inside diameter. Take your time and get it fit up with zero mismatch aka "high-low".Use spacers or a welding rod to achieve a 1/8" (3.2mm) gap ..make sure both ends of pipe are taped along with the joint itself taped shut, and purge gas is on and flowing at around 15 cfh and wait for about a minute before welding the first tack weld. quality control requirements and procedures, weld joint inspection, nondestructive testing, repair of weld defects, and postweld treatment.
