Hello all, Our company received an order in which client is insisting welder qualification to be done as per IS 817, and ASME WPS can be used . Now my doubt is can we usw ASME WPS to qualify welder in IS.

Dear Experts...Please Explain. How to get magnetization for carbon steel material (like...A53,A106,API 5l) during fit up fabrication activity  and how to rectify to proceed welding works. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

 I suggest you to Qualify in 3G . The 3G welding certification qualifies a welder to weld flat, horizontal, and vertical or 1G, 2G, and 3G positions , also includes the 1F, 2F, and 3F positions without having to take the 1G and 2G certification. This one test qualifies you for three positions . On Thu, 20 Jun 2019 at 17:52, K K < karan.hbl@gmail.com > wrote: Dear Experts, Please clarify me regarding below mentioned doubts. As per AWS D1.1 1)        As per PQR thickness qualified with 25mm(Test coupon ) But In WPS thickness mentioned 28MM ( 3.2mm to unlimited )   As per AWS D1.1 Table   4.2 For thickness range is qualified for 25 mm ( 3mm to 2T) if i am correct. 2)     Regarding Position – PQR is qualified with 2G( Horizontal) But in WPS welding Progression – Uphill. whether 2G can weld Uphill position.  Please clarify me regarding above points.

Gents, Is the any specifically prepared PAUT procedure required for examination of ASTM A182 F22 Cr-Mo base material or common procedure used for carbon steel can be used for this material as well? best regards, Eshan

Position  is essential  variable you have to in 3G also,  On Thu, 20 Jun 2019, 17:52 K K, < karan.hbl@gmail.com > wrote: Dear Experts, Please clarify me regarding below mentioned doubts.

Dear ; As such no difference as far as MTC concerned.  ASME starts  with SA and ASTM with A . For example ASTM-A-106  and ASME-SA-106 . But ASME dose not cover all items of ASTM.    American National Standards Institute, also abbreviated as ANSI , and the American Society of Mechanical Engineers, also abbreviated as ASME , are both non-profit organizations mainly focusing on bringing uniformity in voluntary standards used in the engineering discipline. code – also known as ASME Boiler & Pressure Vessel Code or BPVC – is the standard that regulates the design, development and construction of boilers and pressure vessels utilized in a variety of industries. ASME takes reference of ASTM in it's publications, so when you raising requisition for any product, such as Valve whose dimensions are defined in ASME B 16.34, you need to refer respective ASTM standards, like A105 if the valve is to made out of forging.

DEAR RAJU: This porosity is most likely due to contamination or moisture content. Bake the electrode . Environmental control is also necessary . Use only quality electrode. for On Fri, 21 Jun 2019 at 13:53, Vaishakh Kc < vaishakhmgr@gmail.com > wrote: Dear Mr Raju, Mention the welding process.
