Dear All,  We have supply some fabrication parts to Australia,hence fillet weld is also need to qualify along with butt weld (As per Australian standard) for the procedure qualification.So I want to know that shall I merge both the joints in single WPS or else I have to make both separate. Please suggest.

Dear Arvind, Impact test is mandatory whenever ,there is lower service temperature,Grades you have specified might be impact tested by the mill,coz these grades are generally used for low service temperature.

Does that mean that if nickel is less than 1% [ 0.023% in my case] then I do not require any test as per Annex B of NACE and only carry out Hardness test and if its less than 250HV10 then its acceptable?

Dear James, Your reply on subject was really helpful. I just wanted to discuss a case of NACE MR0175 Suppose if Welding wire manufacturer (ER70S-2 & ER70S-6) has not specified any NACE compliance in MTC and if weld Zones meeting Hardness requirement of 250HV10 then does that STILL mean that we comply NACE requirements? Also I would like to understand more of this statement; Welding consumables and procedures that produce a deposit containing more than 1% nickel are acceptable after successful weld SSC qualification by testing in accordance with Annex B.

Hi,Friend There is no ready made formula for shrinkage calculation for ESSC weld overlay in ID of shell  but shrinkage assumption is on the basis of experience and data recorded Shrinkage depends upon Thickness of the base metal, Strip size i.e. 30,60,90 mm width,used Current used etc Generaly lower width with lower thickness of base metal and higher ID of a shell  will have more shrinkage than Higher thk base metal with higher width strip used You will find more shrinkage for a thickness of 50mm -100mm thk shell with ID above 2.5mtr than >100mm thk shell My experience of shrinkage allowance   is about 2.5/ 3mm/meter   you take circumstantially or In other word  ID will contract /shrink about 3mm/mtr in dia Regards Hegde Prakash On Wednesday, 20 September 2017 12:16 PM, 'Thaksen Ingole' via Materials & Welding <materials-welding@googlegroups.com> wrote: Dear Members, I  would like to know how to calculate the weld overlay shri...

Dear Members, I  would like to know how to calculate the weld overlay shrinkage. For eg. We are performing a weld overlay of SS 347 on SA-387 11 2 plates with an ESW process. The weld overlay will be done after the plate is rolled. The ID of the plate is 2500mm. So what shall be the rolled ID prior to weld overlay so that after weld overlay the ID shall not be less than 2500. If its slightly bigger that would be acceptable but should not be too big else we shall waste time and material. Could someone guide me to know the formula for the weld shrinkage of the weld overlay. Thanks and Regards
