Materials & Welding

Dear Ganesan In general you can qualify welder and welding operator and the procedure with both standards, but about 6GR that is defined in AWD D1.1, this position covers all other positions, but in ASME Sec. IX because you shall mention this position as a special position, the qualification range will be just this position. About the testing according to ASME and AWS, test description and dimension are the same. You have to care just about ranges of qualifications.   Regards On Tue, Aug 30, 2011 at 5:13 PM, Ganesan Nallathamby < ganesan6133@hotmail.com > wrote: Dear Experts   I'm not sure if either AWS D1.1 and/or ASME Sect.

Philip, I just finished working on a project with the same material specification (USAN Project) You did not mention the welding process you intend to use as that will determine the choice of consumable. API 2W Gr. 50 (TMCP) is design to have an improved Impact property at low temperature. With reference to your query, 1.       The thickness combination especially the T1 (Bevelled) will be selected in other to cover the thickness ranges in production. If the project specification refers you to AWS D1.1 code as a reference code without additional conditions, then refer to AWS D1.1 table 4.2 for your thickness selection. Using the standard pipe 8" sch. 80/sch. 140 (refer to figure 4.27) will qualify tubular diameter of 4" and above with thickness of 5mm to unlimited, but i know that your client specification might over ride this clause. Note that the thickness selected has little to do with the impact property but rather, your choice of consumable and the welding paramet...

Hello Gents,   I want to   carry out  a welding   procedure qualification testing for  wel ding jackets structural member s , the applicable construction code is AWS D1.1.

In general   Welders performance tests are governed by codes and prepared in accordance with WPS suitable for the work to be undertaken. Colour change might be suggesting some changes in electrical characteristics, but it certainly is not a base sufficient enough to reject the weld. Kindly apply the requisite tests for the weld in question if visually you are satisfied with the weld.   The acceptance criteria for weld performance test shall apply in deciding the disposition of this weld and the ability of the welder to fabricate a sound weld that meets the requirements of the applicable code.     From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of sedef pala Sent: 26 August 2011 07:44 PM To: materials-welding Subject: [MW:12313] change in welding color in Cr Mo V steel   Hi to Everybody, Attached i included two photos from welding (material Cr Mo V steel, process TIG ).

Thank you Pradip for your effort concerning your your research about this material. Really, as I work in the metallurgical and welding field, There is a customer who asked me to suggest him some filler material for welding this material grade CD4MC4. All I know is that material is used for some pump components. On my side, I will continue to find out more about this application. As soon I have the information, I will share it with you.   Thanks again.   Khemici Badri, Ing., M.Ing SODEL De : Muni Andy <cmkfc07@gmail.com> À : materials-welding@googlegroups.com Envoyé le : Samedi 27 Août 2011 8h08 Objet : Re: [MW:12315] RE: 12305] CD4MC4 matraial The material may be CD4MCu.may be u appears is 4 in handwriting. pls check.

dear , It is difficult to weld galvanized pipe , first you have to grind the ends of the pipe to be welded , you can use E70S3 for carbon steel galvanized pipe ,when zinc burn off it produce smoke, it can cause health risk.
