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 & P22)
- 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.)
We continually monitor the advancement in welding technology and techniques, currently employing the following methods:-
- Gas Tungsten Arc Welding (GTAW)
- Shielded Metal Arc Welding (SMAW)
- Gas Metal Arc Welding – MIG, MAG (GMAW)
- Flux Cored Arc Welding (FCAW)
- Plasma Arc Welding (PAW)
- Brazing / Silver Brazing (TB)
Products we manufacture include:-
- Pressure Vessels. Vessels in special alloys, or of specialised design requirements are manufactured for Onshore, Offshore and Nuclear applications.
- Pipework Spools
- “Y-Type” and “T-Type” Strainers. Used in filtration and process industries
- Inlet / Outlet Header Assemblies. Used in heat transfer
- Access Fittings. Produced in various alloys, including exotic, used in process piping for chemical injection / corrosion monitoring.
- Floats and Vibrating Forks – Magnetic and Vibrating Level Switches, used in all areas where fluid measurement and control is required.
What exactly is welding and fabrication?
It is quite common for the terms ‘welding’ and ‘fabrication’ to be used interchangeably, but they are not exactly the same. Welding is the joining together, or fusing, of two or more pieces of metal (or other materials) that have closely comparable compositions and melting points. Fabrication is the entire process of fabricating or creating a metal product from scratch. This includes everything from design and layout to forming and finishing.

What processes are involved in welding and fabrication?
There are of course various different welding methods, including TIG (the most common type of welding in fabrication workshops), oxy acetylene and gas metal arc welding.
Here at Arc Alloys we hold in excess of 100 welding procedure qualifications in a wide range of materials including Carbon & Low temp steels, Stainless Steel, Duplex & Super Duplex & C276 to Norsok M601-2016, CuNi 70/30 & 90/10, Titanium, P91, P11 & P22, Inconel 625 & Monel 400 just to name a few. All of our welding processes and procedures are certified by independent authorities and comply with international standards that include ASME IX and ISO 15614.
Some of our procedures also make use of additional testing to meet customer specific requirements e.g. G28A, G48A corrosion tests (BP Wood Group, Chevron etc.)
