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. All current SWPSs are available in the AWS Bookstore. It stays closed and helps to keep argon in until the joint is closed up, and then opens up under pressure.If you forget to put a big enough vent hole, and forget to cut the X, you could wind up with a low place and it might fail inspectionThe inspection criteria for the root pass of this test is flush to 1/8" of reinforcement.So anything below flush is cause for rejection.This is part oneThe next videos on this topic will deal with the hot pass and cover pass.see part 2 of ua41 6G weld test heregood luck welder. An eddy current test is a non-destructive test (NDT) that uses the principle of electromagnetism to detect flaws in metal objects. This procedure isn't suited for structural applications because it is designed for thin sheet metal, approximately 1 to . 1. Welding is a special process (as per ISO 9001) that makes it necessary to make sure that the welder is capable of doing the job correctly. Scope 1.1 This section covers the bend testing of fillet welds. ), 5) GMAW-S (Short Circuiting Transfer Mode), 6) GMAW (Globular, Spray or Pulsed Transfer Mode), 7) FCAW (Fluxcored Wire Variation of GMAW). What is Bend Test in welds, & Types of Bend Test. However, welding can also cause defects in the weld joint that may weaken the structure. The penetrant is forced into the weldment by capillary action and drawn out by the action of a developer. for the hot pass, and back to 3/32" filler rods for the cap. Destructive Testing is a type of testing which involves the deliberate destruction of a weld for weld testing. Magnetic particle testing (MPT), or magnetic particle inspection (MPI), is a type of non-destructive testing (NDT) that is used to inspect & locate surface & subsurface imperfections in ferromagnetic materials. Visual Testing is a method of inspecting welds and weldments for defects. The typical specimen dimensions for plate and pipe. In general, hardness usually implies resistance to deformation, and in the case of metals, it is a measure of their resistance to plastic or permanent deformation.

The course will focus primarily on the 12" butt weld along with the 12" on 12" branch connection. The sample is braced as shown in the Below figure and ruptured by giving one or more sudden heavy blows with a hammer at the point of the nick or the notch as indicated. Helmets, Weldmonger Brand Soft Durable Welding Welding is the process of joining two or more pieces of metal by heating the pieces to their welding temperature and then bringing them into contact with each other. 0000080454 00000 n Not sure what it is with the AWS. Thats why I recommend letting the pipe cool completely after the root pass is in.IF the root pass was heavy enough , the hot pass pretty much fills up the groove on these pipe couponsbut if you are still below flush more than 1/32" , you probably want to weld another fill pass before the cap. 0000080152 00000 n A Charpy impact test is a welding test used to determine the toughness of a welded joint. Solvent-based penetrants, however, are more aggressive and can cause damage to the weldment if not properly removed. It is the intent of the AWS B2 Committee to have SWPSs only for commonly welded materials and common manual and semiautomatic welding processes. In other words, a welder can be qualified to weld both carbon and stainless steels using one test.That is why the UA-41 test is a frequent test used for the gatekeeper test to get a pipe welding job.Passing the UA41 or any other 6g weld test all starts with metal preparation.The bevel needs to be accurate at 37.5% plus or minus 2.5% that is very important because If the bevel is too steep, the root will not go in well. A young green pipe welder asked an old salt one dayHow can I make the weld on the bottom of the pipe look like the top.The old salt replied.Screw up the top Welding everything, from the crack of dawn to a broken heart. 0000082757 00000 n The specimen is mounted on an anvil provided with a stop block. C) **Position for side 1: 2F - Plates and axis of weld horizontal. %PDF-1.3 This standard introduced the concept of the SWPSs in addition to a set of rules for qualifying welding procedures, welders, and welding operators. 0000080914 00000 n For 25.4 mm t, length and width are 355 and 90 mm; for 19 mm t, the corresponding dimensions are 127 and 51 mm. But only one is for aluminum. 0000079061 00000 n Resistance welding (RW) may not generate the volume of fumes created by gas metal arc or shielded metal arc welding, but capturing whats produced during this process must still take place. 28 Fillet Weld Break and Macroetch Test PlateWelding Operator Qualification, Option 173 29 Fillet Weld Root-Bend Test PlateWelding Operator Qualification, Option 274 AWS D14.1/D14.1M:2005 The American Welding Society, acting under ANSI rules for consensus standards, publishes AWS Standard Welding Procedure Specifications (SWPSs) which are initiated by the B2G Subcommittee on Procedure Qualification Records.

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! i have certifications for ua tests # 1,14,21,22,41, & 91. i would be glad to share my knowledge. 0000000016 00000 n 101 Carbon Steel using BAg-7, Torch Brazing of P/S No. 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. B1. Non Destructive Testing (NDT) allows welders to detect these defects and fix them before they cause any problems. Visual inspection is simply looking at the weld to see if it meets the requirements. Radiographic testing, also known as RT or X-ray, Non Destructive Testing-Examination (NDT/NDE), Lack of Fusion in Welding-Causes-Remedies. Visual testing is typically performed by a welder who is qualified to inspect welds. In initiating SWPSs for consideration as AWS standards, the B2G Subcommittee is guided by the successful service experience in welded construction of the combination of base materials, welding process(es), and welding filler metals covered by the scope of each SWPS. fillet weld on one side of assembly SMAW Electrode: E7018 Minimum preheat and interpass temperature 50 deg. 399 66 Horizontal (2F) A radiograph is a picture of the weld that is created by radiation passing through the weld and striking a film on the other side. To complete this task, the B2 Committee needs as many aluminum PQRs as it can acquire from industry and is asking those who have any that they can donate to contact Jim Sekely, chair of AWS B2D, at jsekely@comcast.net.
