Re: [MW:14257] RE: 14217] Flux-Electrode Combination required.

Generly Normalizing + SR of 7018 catagory weld will not give required UTS of SA516 Gr70  as it deteorates the value Therefore It is recomeded E9018 with higher Mn for welding Gr70 CS which undegoes NR but However more than 50 thk weld  with more than 2hrs Soaking time of NR even E9018 is not suitable.In such case The D/E of Crown and petal construction is recomended (With B2 having Cr is not suitable for such NR condition) Incase of SAW process there is no suitble wire and flux combination (Even EH14 is not good) some time you can try EA3 or EF3 (SAF 5.23) but not for higher thk  To get good results you may high to make trials with NR time and temp   Regards   Hegde P.B. 08805593046 --- On Sun, 13/5/12, kannayeram gnanapandithan <kgpandithan@gmail.com> wrote: From: kannayeram gnanapandithan <kgpandithan@gmail.com> Subject: Re: [MW:14255] RE: 14217] Flux-Electrode Combination required.
