If you explore in the commercial market, you may get 410S or any other SS, hard facing and also made to order
(mostly made in Europe, Australia, and likewise) 0verlay sheets/plates in various lengths and thicknesses including
3 mm thick.
You can join the them directly on the base using E 309L / ER 309L type consumables
and also may help to avoid
PWHT if needed.
Otherwise, you have to follow conventional methods only.

Generaly tube sheet is being explosion boded with 410 S on CS and tube to tube sheet welding is carried with 309L/309MoL metallrgy and PWHT to be carried with respect to P1 material i.e. at 600-610C (donot increase the temp beyond 640C) It is prefered to weld T/T sht joint by GTAW Regards Hegde P.B.

When your shell is SS, tubesheet has to be solid ss; cladded tubesheet will not be effective. Check the design. Anyway recommended tubesheet is explosion bonded material. It is very tricky to weld tubes to tubesheet (with weld overlay)and that too with PWHT; cracking is a big concern.

Subject: [MW:17817] Welding and cladding SA-516 Gr. 60 + AISI 410S I have shell 20mm thick ( SA-516 Gr, 60 ) and there must be cladd AISI 410S 3mm Could anybody tell me which filler i can use, for SAW and GMAW? GMAW i planning use for flanges and tubesheets ( after i overlay tubesheet - what is procedure for welding tube to tubesheet? ) Also PWHT has been asked by customer after overlay.
Can anybody tell the effect of PWHT on SS 410S overlay?
What will be the the safe range of temperature of PWHT? ( Also recommended temperatures and times, holding cooling...) -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/http://www.linkedin.com/groups/MaterialsWelding-122787?home=&gid=122787&trk=anet_ug_hm The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents. --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.
