Filler metal selection - Metal and Metallurgy engineering - Eng-Tips
2015年2月19日 · When it comes to selecting filler metals, I am aware of the considerations such as base metal matching strength, welding process and welding position do matter. I recently came across a wps where ER-347 was used in the TIG welding of F91 and A105. ER-347 contains about 19-21% of Chromium whereas base metal, this case, F91 contains 8-9.5% Chromium.
Classifying ER70S-6 as A-No. 1 - ASME (mechanical) Code Issues
2007年4月5日 · Most filler metal manufacturers class ER70S-6 as F-No. 6, A-No. 1. However, both Mn and Si as listed in SFA-5.18 can exceed the limits of QW-442. So my question is, in order to classify this wire as A-No. 1, do I need a certified MTR from the manufacturer for every lot of wire which we use in...
F-Number and A-Number - AWS (welding) Code Issues - Eng-Tips
2015年7月30日 · As per QW-442 A.No is for the Classification of Ferrous Weld Metal Analysis for Procedure Qualification and QW-432 F-Number is for Grouping of Electrodes and welding rods for Qualification. Why is "F" and "A" were used for F-Number and A-Number respectively? Does "F" means filler and "A" means analysis? Thank you very much.

2012年1月31日 · Trying to generate a WPS with all F-No 3 filler metal would probably not satisfy weld deposit thickness requirements for the root and fill. In your specific case, a new WPS should be written using the original PQR that supports a F-No 3 weld root and F-No 4 fill in accordance with the weld production requirements.
filler metal to weld astm a743 ca15 (a296 ca15) - Eng-Tips
2009年4月4日 · The preheat requirement would be 450 deg F minimum. Post weld heat treatment (PWHT) would be in the range of 1200 deg F to 1400 deg F (depending on the final strength level required) for time based on the thickness of weld deposited. The cast 410 stainless is readily weldable with preheat and PWHT maintenance and would not require welding in ...

2020年11月1日 · A-Numbers only apply to ferrous metals. This filler metal would not be considered to be a ferrous metal considering the percentage of iron is less than 2%. If these are single pass welds, there could be sufficient iron in the weld deposit to fall into an A-Number group due to the weld being diluted with CS base metal.

2005年5月8日 · The designer is on their own. In your case you have several options for filler metals based on the alloy content and strength of the lower of the two P-No's (P-No1) or the higher strength and alloy content of the two P-No's (P-No 4). Most people tend to use the higher alloy and strength P-No material in a weld joint for selection of the filler ...

2006年3月14日 · GTAW lists paragraph QW-404.14 that states the addition of or the deletion of filler metal is an essential variable. QW-404-.5 lists A number as an essential variable. Under laser welding paragraph QW-404.14 (addition of deletion of filler metal)is again listed as an essential variable, but QW-404.5 (A number) is not listed.
Filler metal for root weld by GTAW in P91 - Eng-Tips
2010年4月3日 · Mr Pandithan. There are tons of examples of P-91 welding with matching filler, which includes, GTAW with P-91 filler.As compared to SMAW,FCAW and SAW, GTAW produces one of the cleanest P-91 weld, with very low O2, Mn:S ratio >50( prevents hot cracking), Total Ni+Mn 1.5% max.
