Re: [MW:17462] E 7018 used instead of E7018-1

QW-404.12 A change in the filler metal classification

within an SFA specification, or for a filler metal not covered

by an SFA specification or a filler metal with a "G" suffix

within an SFA specification, a change in the trade designation

of the filler metal.

When a filler metal conforms to a filler metal classification,

within an SFA specification, except for the "G" suffix

classification, requalification is not required if a change is

made in any of the following:

(e) from a classification that requires impact testing to

the same classification which has a suffix which indicates

that impact testing was performed at a lower temperature

or exhibited greater toughness at the required temperature

or both, as compared to the classification which was used

during procedure qualification (i.e., a change from E7018

to E7018-1)

SO 7018 IS NOT ACCEPTED IN PLACE OF 7018-1

I think 404.10 is for SAW process, here is the case of SMAW process.

E 7018 can not replace E 7018-1, as there is no weld metal chemistry defined in Sec II C for E 7018-1, also there is no F No. for E 7018-1 as per section IX.

Dear

 

Qualify Welding procedure with E7018 and carry out tensile, bend & impact testing...if all tests are OK you can convince your Client those weld joints are meeting requirement of impact properties.....

Dear Experts,

 

Our welders are used E7018 instead of 7018-1 for A333 Gr-6.

Now client is asking to cut the joints.

Moreover they are asking to prove the remaining joints whether they are welded with 7018-1 or not.

Can anybody suggest a suitable method such as any NDT to prove that ?

So please send your valuable suggestion with reference to code.

 

Thanks & regards,

 

Binu.
