As you said ,Test coupon is 50mm thick with GTAW 25mm and SMAW 25mm welding. Generally GTAW is used for root and hot pass, not for 25 mm. If you do 25 mm GTAW WELDING,  your production rate as well as welding cost will be more. Follow  ASME Sec IX QW-451.1, It will be helpful for you On Sun, Mar 31, 2019 at 7:56 PM George Dilintas < dilintas@gmail.com > wrote: you are confusing the base metal thickness range and the deposited thickness range.

Hi, I am new to this topic. I have to solve the engineering part of doing the calculation. Here is the statement of problem--> Take the actual nominate tube and tube sheet material, conduct analysis mathematically to estimate the joint strength.  Conduct analysis to estimate the maximum expansion the tube can take without affecting the integrity of the tube section. (Check the wall thickness reduction in %)  Once the maximum expansion on tube has been calculated, check the tube to tube-sheet joint:  0.25mm oversized hole with the tube at maximum expansion  0.5mm oversized hole with the tube at maximum expansion  0.75mm oversized hole with the tube at maximum expansion Nominal tube diameter-38.1 mm > Nominal tube sheet hole-38.56 mm  tube thickness 3.2 mm Tube material SS 304 TEMA Extract (values in mm, bracket in inches 38.10 (11/2)  Tube nominal dia 38.56 tube sheet nominal dia (1.518) 0.18 under tolerance  0.08 over tolerance  (0.003) I have calculated maximum expansion of...

Pl ref QW 451 for base metal and weld metal. Hope that u agree with base metal thickness ( T) range. For weld metal (t) thickness range is as follows, if deposited weld metal thickness is less than 19mm, then range is 2t. And deposited weld metal equal or greater than 19mm, then thickness range is 200mm.

I would advise to read QW-409.1 and the appendix H in ASME IX. When impact test is applicable, heat input becomes a supplementary essential variable. New PQR is required when heat input is increased. So, considering the calculations of heat input given in QW 409.1 you have to record the max heat input per pass Στις Κυρ, 31 Μαρ 2019 στις 5:34 π.μ., ο/η Gowtham Rajendran < rajgowthamiwe@gmail.com > έγραψε: I.e Heat Input is different in various layers for the fillup passes.

Wrong, you should read UCS-79 carefully. The HT is a function of P-No and extreme fiber elongation, and service conditions. UCS is applicable for carbon steel materials For high alloy (example stainless steel) pls refer to UHA-44 For enhanced ferritic steels pls read UHT-79.

Alloys shall be acceptable if the alloying elements are each within 10% of the specified range of values. 10.2 Welds with consumables that match, or nearly match, the base metal composition shall be within ±12.5% of the ranges allowed in ASME SEC IIC for each element. 11 Rejection Procedures 11.1 If the PMI testing results fall outside the acceptable range using a method described in Section 8, the Equipment Manufacturer or the Fabricator, as applicable, has the option to conduct a more accurate analysis at his own expense to determine the component acceptance such as obtaining a chemical analysis performed by an independent testing laboratory. The alternative test method or independent laboratory must be acceptable. The results of the more accurate test method or independent chemical analysis shall govern. 11.2 If...
