When you use ESAB products, 

amazing things happen. 

In the harsh environments of the power 

generation world, even everyday jobs 

aren’t simple. Fortunately, your choice 

of a welding and cutting manufacturer 

is. As the global authority on welding 

and cutting, ESAB offers the broadest 

selection of world-class products 

that meet the tough demands of the 

industry. From turbine plants to nuclear 

containment vessels, choose ESAB for 

powerful solutions. 

Power generation Technology 

Creep resistant steels were originally developed to 

provide improved strength at elevated temperatures. 

These creep resistant steels were metallurgically 

designed with additions of chromium, molybdenum and 

other similar alloys to produce the needed strength and 

creep resistance required in most steam generating 

facilities. Applications include heat exchangers, 

header systems, and associated piping within a power 

generation facility. Some of the most common grades 

of creep resistant steels include P11, P22, P5 and P91. 

Each of these grades has a varying amount of Cr-Mo and 

other assorted alloys added. 

Creep resistant steels require the use of comparable filler 

metals that perform at the same level as that of the steel. 

It is essential that the choice of filler metals complement 

the steels while optimizing the creep resistance. In 

addition, the mechanical properties of the filler materials 

should adequately produce the toughness needed during 

the start-up phase of the plant equipment. 

PoWEr gEnErATion TEChnology 

Because of the wide variety of creep resistant steel types, 

the selection of filler materials is also varied. Historically 

products such as 1.25% Cr, .5% Mo or 2.25% Cr, 1% 

Mo would have been used. Today however, due to the 

increased demand for energy, utilities are operating their 

facilities under peak load conditions causing them to 

choose another grade such as P91 over one of the other 

creep resistant steels. 

The designation most often associated for the applicable 

filler metals for welding P91 grade steels is a “B9”. ESAB 

offers a complete line of “B9” filler metals for the SMAW, 

GTAW, FCAW and SAW processes. Each of these 

products is tested in accordance to the respective AWS 

specification and can be certified to the respective ASME 

specification, if need be. Each lot of material is lot tested 

and certified prior to the sale. If additional testing is 

required, ESAB can accommodate such testing. 

Throughout the years, the Atom Arc ® , Arcaloy ® and Dual 

Shield ® brand names have been synonymous with 

both fossil fuel facilities and nuclear power plants. The 

engineering design built into these products has provided 

fabricators with the highest level of reliability possible. 

The technical information contained within this catalog 

provides the supporting data to substantiate our vast 

knowledge and experience in the development of 

products to support the power generation industry. Since 

all such product is produced in accordance with the 

ASME Quality Assurance System, customers can take 

comfort in the fact that these products meet or exceed 

their most stringent specifications. Feel free to contact us 

for further information or to discuss a specific application.

Dual Shield 7000-A1 is an all-position flux cored electrode 

recommended for 0.5% Mo steels. It is used in the 

fabrication and erection of boilers, pressure piping and 

tubing, and other pressure vessel applications. Shielding 

gas of 100% CO 2 and 75% Ar, remainder CO 2 may be used. 

A 75% Ar/25% CO 2 shielding gas mixture is recommended 

to improve arc characteristics, increase wetting action, 

decrease penetration, and provide easier arc control for outof-position 

welding. The weld metal analysis is similar to an 

E7018-A1 low hydrogen electrode.
