Welding and Fabrication Services

Welding and fabrication has been at the core of Arc Alloys business since 1998. We now have an established reputation for manufacturing products, which operate in severe environments, to the highest levels of quality and stringent levels of dimensional accuracy.

All our welding procedures are certified by independent third party authorities to international standards including ASME IX and ISO 15614.


Our qualified procedures cover material grades which include the following:-
Carbon Steels
Carbon Steels with P.W.H.T.
Low – Temperature Carbon Steel (A333 Grade 6)
CrMo Steels (P11)
300 Series Stainless Steel (304, 316, 321,347)
Super Duplex
Inconel 625
Hastelloy C276
Carpenter 20
Monel 60 (Alloy 400)
Dissimilar Combinations.

Some of our procedures also have supplementary additional testing to meet customer specific requirements e.g. G28A, G48A corrosion tests (BP Wood Group, Chevron etc.)

Welding Processes

We continually monitor the advancement in welding technology and techniques, currently employing the following methods:-
Gas Tungsten Arc Welding (GTAW)
