sathyasaravana0,

excuse me when I am asking, but have you already seen the information under:

http://www.aws.org/cgi-bin/mwf/topic_show.pl?pid=63556#pid63556 ?

If these information - besides the already given ones coming from Prof. Crisi from Brazil and Shane Feder from Australia - weren't helpful perhaps it would help, to give us some more detailed information about the later usage of the part you have welded.

I am certain many other colleagues in the forum would share their experience if more details were known.

Generally the standardization of the base materials according Euronorm EN 10025 is founded on their yield-strength in MPa.

This means:

- S 355 J2G3 has a lower yield-strength of ~ 355 MPa (a "St 52-3 N" according to the former - and meanwhile invalid - German standard DIN 17100)

- S 275 (JR?) has a lower yield-strength of ~ 275 MPa (a "St 44-2" according to the former German Standard DIN 17100)

Under using these mechanical data you can likely find easily the correct filler-material for your welding application. Although - as I have mentioned in my post in the Technical Section - from my point of view these materials were normally weldable by using a basic electrode of type E 7018. Exceptions were - of course - possible and would - from my point of view - depend on the later utilization of the welded parts.

Regards,
Stephan
