Hi All,
Code: API 1104
We have a qualified WPS with the electrode E8010-P1 (Manufacturer ESAB).
We are obliged to use the electrode E8010-G (Manufacturer Lincoln Electric).
According to paragraph 5.4.2.6 of API edition 2013 Addendum 2016 can we use E8010-G instead of E8010-P1 WITHOUT re-qualification of the WPS or do we have to re-qualify our WPS.
Thank you in advance for your help.
5.4.2.6 Filler Metal
The following changes in filler metal constitute essential variables:
a) a change from one filler metal group to another (see Table 1);
b) for Groups 1 through 3 in Table 1, any change in suffix designator except within the group consisting of:
— no suffix designator,
— -1,
— A1,
— C1, C2, Ce,
— C1L, C2L, C3L,
— M,
— P1, or P2;
NOTE For example, a change in suffix designator from A1 to B3, or vice versa, constitutes an essential variable. A change
from A1 to C3, or vice versa, does not constitute an essential variable.
c) for any filler metals with a G suffix designator only, a change in the manufacturer or trade name;
d) for materials with a SMYS greater than or equal to that of the material specified as API 5L Grade X65, any change
in the AWS classification of the filler metal (see 5.4.2.2).
NOTE Except as indicated items in b) and c) above, changes in filler metal within filler metal groups may be made within the
material groups specified in 5.4.2.2, items a) and b).
The compatibility of the base material and the filler metal should be considered from the standpoint of mechanical
properties.
