Materials & Welding

Hello everyone, I hope you are all doing well. I am seeking technical assistance in developing a welding consumable estimation format for pipeline fabrication. For reference, consider the following joint configuration: Pipe Size: 16-inch Wall Thickness: 12.7 mm (XS) Welding Process: GTAW (root & hot pass) followed by SMAW (fill & cap) I would appreciate a standardized consumable-calculation template —preferably in Excel or PDF —to accurately determine filler metal requirements, deposition rates, joint volume, and allowable tolerances for this type of weld. Thank you in advance for your support and technical guidance. B est Regard s MD MASUD RANA QA-QC Inspector(Welding & Piping) Mechanical Engineer. Pipeliners Limited.

Dear Mr. Mahmood, Please advise your welder , before welding, take a piece of emery paper and rub the entire surface of TIG wire then start welding. Please proceed with Pickling and passivation after this.

Hi Zakaria, Hope it is piping material and generally we use GTAW + SMAW welding processes to weld such stabilized grade material. For SS347H material, the recommended welding consumables are AWS ER347 for Gas Tungsten Arc Welding (GTAW) and AWS E347 for Shielded Metal Arc Welding (SMAW) . Please check your customer's specifications for PWHT and other requirements. Being stabilized grade PWHT is recommended at 900 deg. cent. temperature for 4 hours.

Dear Bilal, Refer to Sec VIII Div. 1, UW-40 (f)5f, the governing thickness for PWHT calculation for  Non pressure # Pressure Part is  the thickness of the weld at the point of attachment. Request calculate Soaking time as per the same. From attached image, it is appearing as a Groove weld across the thickness.  Regards, Mohammed  On Thursday, October 23, 2025 at 9:49:19 PM UTC+5:30 Prem Nautiyal wrote: Please proceed with PWHT considering 50mm butt weld size thickness of Trunion ..

Dear Experts, We seek your valuable insights regarding the welding, shell rolling, and dish forming processes for a clad steel reactor comprising 40mm thick SA515 Gr.60 base material with 3mm Inconel 600 cladding ( Produced by Explosion Bonding Method). Preliminary references suggest that pre-heating may be necessary during rolling, forming, and welding operations due to the dissimilar material combination. Additionally, maintaining inter-pass temperatures between 100°C and 250°C is advised to prevent clad layer disintegration. ENiCrFe-3 has been recommended as a suitable filler metal for both cladding and transition layer welds. As we are  new to this material combination, we would greatly appreciate expert opinions on critical considerations, best practices, and potential challenges associated with these fabrication steps. Looking forward to your guidance. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message b...

Dear Team,      I want to confirm about the consumable selection and PWHT requirement (chromium content greater than 3%) for tube to tubesheet joint. Material is listed below, 1. TUBE SHEET:  SA 182 F6A CL2(P#6 Gr.3) 80MM thickness. 2. TUBE : SA 213 T9(P # 5B) 19mm dia 3 mm thickness. Below confirmation is requested, 1. Consumable for GTAW? 2. PWHT requirement?

  Mr. Bilal, Your base m etals are,  Tube Sheet: SA 182 F6A Cl.2 → P-No. 6, Gr. 3 (13% Cr martensitic stainless steel)  and  Tube: SA 213 T9 → P-No. 5B (9Cr-1Mo ferritic steel). Recommended GTAW f illers are ER80S-B8 for strength-bearing joints. Though ER 309L/ER309LMo are   used for  dissimilar welding between Cr-Mo and martensitic stainless steels, buttering helps prevent hard,  brittle martensite  at the fusion zone. ERNiCr-3 (Inconel 82) is a better choice for providing crack resistance  and avoiding PWHT; i.e.,  for buttering, you can use ERNiCr-3, and for tube welding, use ER80S-B8. PWHT is not required for tube-to-tube sheet seal welds. B uttering with ERNiCr-3 or ER309L also helps to  avoid  P WHT in the assembly, as it controls hardness. C Sridhar.
