Liquid Penetrant Testing (DP Test) is a nondestructive testing (NDT) method that uses a penetrant liquid to detect discontinuities in a weldment. In through-transmission testing, a probe is inserted into the material and ultrasound is transmitted through it. 0000079298 00000 n
It is the intent of the AWS B2 Committee to have SWPSs only for commonly welded materials and common manual and semiautomatic welding processes. 399 0 obj <>

For example, radiography can detect very small defects, but it can be expensive and time-consuming. A destructive torque test is normally required to verify that a minimum specified torque can be achieved at the settings selected.

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. your Facebook account, or anywhere that someone would find this page valuable. 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. 0000079625 00000 n
Tig Welding Tips - UA41 6g Pipe Welding Test (re-uploaded) Both carbon steel pipe but the UA 41 is TIG and with 309 ss root and fill.
To ensure that welds meet these requirements, they must be tested. Eddy current testing is often used to inspect welds for defects. Its goal is to create procedures to support the more-common base metals in the 5xxx and 6xxx series alloy groups, welded primarily with the gas metal arc welding process, using both 4xxx and 5xxx series filler metals, and within a range of base metal thicknesses conducive to the most-common structural applications.

feather edge, a 3/32" filler rod for the root pass, a 1/8" filler rod Weld Testing methods can be classified into two main types:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[468,60],'materialwelding_com-box-3','ezslot_19',600,'0','0'])};__ez_fad_position('div-gpt-ad-materialwelding_com-box-3-0'); The most common weld testing methods are manual visual inspection, radiography, ultrasonic testing, magnetic particle inspection, and liquid penetrant inspection. 107 Metals per NFPA-99, 1995 Edition using BCuP-3 through 7 filler metal without flux, (for a P-number Base Metal Welded to Itself), (for Two Different P-number Metals Welded to Each Other), X is the P-Number of the Base Metal (or Metals). This creates a magnetic field which causes currents to flow through the metal object in a circular pattern (eddy currents). Visual Testing is a method of inspecting welds and weldments for defects. 0000081637 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. This procedure isn't suited for structural applications because it is designed for thin sheet metal, approximately 1 to . I bought these pipe test coupons from triangle engineering 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.
PDF AMERICAN WELDING SOCIETY WELDING INSPECTOR EXAMINATION Part B The manner of positioning the specimen and the direction of force is also shown in the above figure. The data to support a Standard Welding Procedure Specification are derived from procedure qualification records (PQRs) generated by the B2G Subcommittee on Procedure Qualification Records and PQRs received from industry and government agencies. Note that passwords are case-sensitive. There are many different types of weld tests (destructive Tests & Non-Destructive Tests) as explained in this post, each with its own objectives.

So I like to use a technique that works well in most all situations.I use the term "Keyhole" a lot in this video. Its carbon steel SA106 pipe about .216" wall thickness, but its welded out using er309 stainless TIG rod. Its very common practice to use carbon steel pipe along with 309 stainless rod for welding tests and in some instances, the welder can be qualified to weld both stainless and carbon steel with one test joint. 0000081545 00000 n
"So hopefully, this video will provide a few tips that will help someone pass a 6g test and get the job they want.This It is used to join two or more metal parts together. *4 Can mild steel be welded to stainless steel?

A welding test is essential for ensuring the quality of welds and preventing accidents. Standard Welding Procedure Specifications (SWPS), Comparison of Commercially Available Welding Consumables. They are thus available to and for the use of NCPWB members only. Limitations have to be placed on the hardness of the heat-affected zone and weld-metal, because if they are too hard, they will not have sufficient ductility for the service conditions and their corrosion resistance may also be impaired. My first question is, what does UA stand for?? If there are any flaws in the metal, they will disrupt the flow of these eddy currents and this will be detectable by changes in the magnetic field. 0000078871 00000 n
Copy and paste it, adding a note of your own, into your blog, a Web page, forums, a blog comment, The hardness of the base metal and weld-metal of a welded joint is affected by chemical composition, the metallurgical effects of welding, cold working of the metal, heat treatment, and several other factors. The document explains the concept of a bend test for welds and what factors, beside poor weld quality, can cause test specimen to fail Need Information on Welding Dissimilar Metals in Heating and AC Piping Systems?
