Re: [MW:10322] Welding of S355JO with ST52-3

Dear HA,
 
This job must be only structural welding.  PWHT may not be required if thickness is less than 38 mm.   E 7018 is best choise and as per structural welding code you can use one level iow strength than base metal can used for better fatigue strength.
PWHT may be required only incase dimensional stability ( machining is required after welding)
