ASME SEC. IX QW-403.10 limits the material thicknes up to 1.1 times of the thickness welded for short circuit transfer when the material thickness is less than 13mm. Does this limitation apply to short circuit+spray arc? I mean, what should be taken into account when a test plate is welded with...

Let's go through an example.our material thickness is 75 mm.Which column i should take?i know the requirements for the last two column is the same.but the last column also covers the previous one? The explanation for the last column in the Table PW-39-1 should be "2 hr plus 15 min for each...

In ASME Sec. I Tabe PW-39-1 and PW-39-2 postweld heat treatment requirements are specified based upon the material thickness.The last colum of the table covers material thickness over 5 inch (125mm) but the explanation for the holding time is like this : " 2 hr plus 15 min for each additional...

Thank you

In EN 15614-1, the last paragraph of the item 7.4.5 says "Where multiple welding processes are qualified in a single test piece,impact test specimens shall be taken from the weld metal and HAZ that include each process" Lets take a test piece with a thickness of 20mm welded with...

But 2 welders can not weld a single test coupon with different processes..Right??

Thank you DVWE!, I didn't pay much attantion to the word "appropriate".Now I got it. Now I also understand why for 19mm and over thicknesses only side bend test has to be carried out according to Table QW-452.1(a).Because Table QW-452.(b) Note-3 says: "Thicknes of test coupon of 19mm or over...

DekDee, Thank you but what I'm asking is different..Let me repeat my question..In a butt weld GTAW+SMAW process,(Root pass with GTAW,filling and cover passes with SMAW) how can I see root pass(GTAW) on the convex surface of a face bend test specimen or how can I see filling and cover pass (SMAW)...

Note 2 says "Coupons tested by face and root bends shall be limited to weld deposit made by one welder with one or two processes or two welders with one process each.Weld deposit by each welder and each process shall be present on the convex surface of the appropriate bent specimen." My...

Some variables in Tables QW-252 through QW-266 are marked both as supplementary and non essential variables such as QW 409.4 and QW 410.9 in table QW 253.I know that supplementary essential variables are considered only when notch toughness requirements are applied.From this point of view why...

Hi everyone, I'm trying to find a reference on ASME Sec. IX for test piece dimensions of butt weld procedure and performance qualification.On QW-463.1(a)(b) and QW-462(a),(b)I can get the length of the test pieces indirectly by adding all specimen width together but how about the width of the...

Thanks David!! It was useful!!

What is meant by "Size of fillet" in QW-462.4(a). Is it leg length or throat length?
