Welding X80, 4130, 8630 with NACE requirements

These high strength steels Pipe Steels X 60-X80 (X100) obtained their properties due to the heat treatment during production. When welding these type of steels the cooling time (T8/5) needs to be as close as possible to the original heat treatment of the steel itself. Recently new welding consumables have been developed based on current knowledge and combined with the experience of the last 30 years.

Fluxcored wires, FCAW for Pipe welding the X –Steels:

Gas shielded seamless metal-cored wire for M21

CEWELD AA B500

This basic seamless copper-coated flux cored wire has a nickel content of less than 1% and meets NACE requirements. A yield strength of at least 500 MPa by PWHT combined with more than 50 joules at -60 °C impact energy and less than 3 ml/100gWM hydrogen make it an outstanding wire in the class (T 50 6).

CEWELD® AA R500 PIPE

This is a seamless rutile cored wire with very good modeling properties, therefore excellent constraint welding with higher amperages is possible. Suitable for use down to -40°C depending on requirements down to -60°C. Especially well suited for orbital welding and basically welding on weld pool backing in all positions, even with high heat input. This wire offers a unique welding deposit with less than 1% nickel to full fill NACE requirements and cover more procedures up to 500 MPa (up to X80) yield strength steels.

CEWELD® AA M500

This a seamless metal cored wire with remarkable stable arc and no spatters. Excellent for use in automated welding applications such as orbital Mag or robotic welding. This wire offers a unique welding deposit with less than 1% nickel to full fill NACE requirements and cover more procedures up to 500 MPa yield strength steels. CEWELD® AA M500 can also be used for constructions that needs post weld heat treatment after welding and still offers mechanical properties confirming 5Y46 class (up to X65). Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage in unconditioned condition.

If PWHT is needed Oil and Gas Steels 4130 (1.7218), 8630 (1.6545) should be welded with:

CEWELD® AA M550

Seamless metal cored wire with remarkable stable arc and no spatters. Excellent for use in automated welding applications such as orbital Mag or robotic welding. This wire offers a unique welding deposit with more than 2% Nickel to offer reliable impact properties down to -60°C (Note NACE). CEWELD® AA M550 is used for welding 550 MPa yield strength steels (up to X80) , due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage in unconditioned condition.

CEWELD® AA B CrMo1

This basic seamless copper-coated flux cored wire has a nickel content of less than 1% and meets NACE requirements. Crack resistant weld metal conditioned by the high-basic slag in combination with very low hydrogen content. Suitable for the economic processing on high-temperature resistant CrMo-steels up to 550 °C. X-ray-proof seams with negligible formation of spatter.

CEWELD® AA M CrMo1

Seamless metal core wire without slag for welding with M21 gas, for heat and creep resistant applications. It has a good arc restricting even with cold wire tip, suitable for robot applications. Ideal for use in short arc and spray arc. Excellent gap bridging for root welding. High-efficiency type for economic production environments and CrMo-steels up to 550 °C (1022°F) . Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage in unconditioned condition.
