Single layer strip cladding solution is possible for SS347 with ES and SA process.
Depending on dimensions and requirements selection to be made :
SA-strip:
OERLIKON AST 300 - SUPRASTRIP 24 13LNb
OERLIKON AST 347 - SUPRASTRIP 24 13LNb
ES strip:
OERLIKON ELT 300 - SUPRASTRIP 21 11LNb (low speed)
OERLIKON ELT 300S - SUPRASTRIP 24 13LNb (high speed)
OERLIKON ELT 347-1 - SUPRASTRIP 19 9LNb (low speed)
In general the ES-strip cladding process can not garantue zero defects (PT-check) after machining in the ovelap zone. SA strip cladding process should be chosen in that case.

Dear all,
I have query regarding the Weld Overlay in Breesh Lock Heat
Exchanger.
As per specifications it is required to give SS347 Weld- overlay with
3mm undiluted chemistry . It is written that weld overlay shall be
lined & Faced. does it mean Strip cladding First then Machining.
Secondly is it possible to offer single layer solution for the same.
IS it required to machine the overlay in Breesh Lock Heat Exchanger.
Thanks in advance
Jaspal Singh
