Dear Sir,
As per table UHA-32 of ASME VIII Div.1 (Post weld heat treatment requirement of P.No.7 Materials) a preheat of 230 deg.C is required if thickness of SS 410S is above 10mm when Austenitic consumables are used.
I have selected 309L type consumable for Welding of SS410S material. Job internal piping thickness exceeds 10mm.
For Overlay/Restoration, i selected 309L consumable with Preheat of 150 Deg.C, interpass of 250 Deg. C. Is it Ok?
I'm confused especially with Code requirement & information from net regarding welding of SS410S material.
I request to provide more information on the same subject with respect to code requirement in welding of SS410s material.
regards

Hi!
As base metal is of LAS , req PWHT at min 650C , Therefore suitable consumable for clad restoration of 410 S clad is E NiCr fe3 or NiCr Mo3
Preheat Temp . of base metal for barrier layer is 100 C , (No need of preheating for subsequent layers. min ,Interpass temp is 175 max, Welding Current – 110-120 Amp for 3 .2 dia electrode.

Subject: [MW:5751] Welding of SA 240 TP 410S material.
Dear all,
Can any body share the experience in welding of SA240 TP410 Material.
I have a Vessel consists SA387 Gr.11 Cl.2 material cladded with SS410S.
Internal Piping material : SS410S thickness 10-15mm.
Construction Code : ASME SEC VIII Div.1.
Welds in SS410S will under PWHT of low Low alloy steel.
Need guidance in Preheat & interpass temperature of SS410 material welding (Consumable selected for welding of SS410S is 309L type).
regards
P.Rao
