Hi, You can specify in the Position column as "ALL POSITION"  Thanks& Regards,   (Karthik) Karthikeyan.S M: +66-892512282 E-mail : k arthik6684@yahoo.com On Saturday, February 29, 2020, 02:51:59 PM GMT+7, Karthik <karthik6684@yahoo.com> wrote: Sorry, last mail specified as QG-101. It should be QW-101. Hi, WPS must address all Essential and Non-Essential Variables used in production welding as per QW-101. Even though position is an Non Essential variable, you must address the position you are going to use in the production welding. Simply you can specify 6G. So you can use this WPS for all position welding. "> Thanks& Regards,   (Karthik) Karthikeyan.S M: +66-892512282 E-mail : k arthik6684@yahoo.com ...

Dear Mr. Selvin, Enclosing  two articles towards, 1. Preheating LAS and  2. Relation between preheat & micro structure  recently up loaded for your study. The second article was published  in the year 2019 in Springer Nature Journal and  will give you an idea towards preheat and micro-structure relation. Trust it will help you. regds, C Sridhar. ------------------------------------------------------------------------------------------------- On Friday, 28 February, 2020, 04:36:31 pm IST, selwin jebadas <selwinjebadass@gmail.com> wrote: Experts, I need some basic understanding from LAS welding. 1)Need for preheat in LAS? 2)Preheat & microstructure relation?

In wps‌,u should have mentioned--All position. WPS is a guideline for the task performar. It should be clear. What ever possible information which will help to the Quality, may be furnished. Example-- preheat-- location of measurement.  On Fri, 28 Feb 2020 11:45 am Rash, < tiamlord@gmail.com > wrote: IF position not an essential variables, why need to change WPS  1G and add 6G position? понедельник, 20 октября 2014 г., 16:29:28 UTC+5 пользователь dili...@gmail.com написал: If your Code is ASME and if your project specifications do not include any additional requirements, then you may proceed as follows: Position is not an essential variable for WPS qualification, so you do not need a new PQR.

WPS is basically a Base line document used by the Welder and Welding Supervisor which need to be Approved by the Client. Client will check with the PQR (submitted by you to client) and verify the Applicable code to approve the WPS which will be used by the welder cross-checked by Welding Inspector. Hence revisions to be made in the WPS according to your shop floor requirement.

Dear Experts. We have purchased martensite SS Cast components complying to 1.4405 (GXCrNiMo16-5-1) However, the manufacturer did not carry out the tempering as required in the specification. We tried to carry out the missing heat treatment locally in UAE and see if the results are satisfactory. The following cycle was used. Holding temp-630C, Duration 1 hr 30 minutes, heating rate from 300 C-100/hr. The test results after the tests are as given  UTS is 1004 N/mm2, Elongation- 6.4% and hardness 376 HV10. The required elongation is minimum 15% and hardness below 240 HV10. Please advise the Heating cycle that is to be followed to achieve the above values. Looking forward to hearing your feedback.

U have to do like sprinkle type flow on the vessel. Do not immerse or forced water flow on the because it will get collapsed. Be cautious in designing your type of water flow. It is very important.  On Thu, 27 Feb 2020 8:54 am harenath jha, < harenathjha@gmail.com > wrote: Material of construction please On Wed, Feb 26, 2020, 20:28 prateik tolani < tolaniprateik@gmail.com > wrote: Dear Experts, one of our client is asking for Solution annealing for complete vessel vessel size - 1300 ID x 6500 mm long, thickness 8 mm with lots of nozzles. whether it is possible. at higher temperature of 1100 Deg C and rapid cooling in water, vessel will distort completely.

Pratap, Considering you have access to welding of clad side, the below procedure can be used. 1. Strip back the clad(C-276) side 5-10mm from the root or toe of the carbon steel(CS) Joint. 2. Weld the carbon steel portion using Groove weld CS procedure(WPS/PQR) existing or qualified based on the applicable substrate or base metal Thickness. 3. You need to Qualify a Clad restoration overlay PQR as below. a. Use a SA36 base plate of dimension 150mm x 150mm x 8mm thicknes. b. ASME Sec.iX QW-453 Table shall be taken as a Guideline. c. USE Welding electrode ENiCrMo-4 and weld a 38mm wide (minimum layers as per requirement of chemistry height) on the 150mm x 150mm plate. d. Perform  following tests. i. Liquid Penetrant examination on the overlay weld sample. ii. Perform 4 side bend test. (Material testing lab will provide you the detail) iii. Chemical Analysis as per specification requirement height from the Top or Fusion layer. Upon qualifying the PQR, restore the strip back clad area by...
