Hardox Steel Fabrication

SWEL Group undertake bespoke fabrications and precision specialist welding for partners in the marine sector.

SWEL finalised this underwater recovery tool fabrication in Hardox Steel.

Hardox is an extremely strong wear resistant steel. The yield strength also varies between steel grades; For example, the typical yield strength of Hardox 400 is 1100 MPa, but the yield strength of Hardox 600 is about 1650 MPa.

Compared to standard structural steels, these values ​​are much higher; For example, S355 has a yield strength around 355 MPa.

SWEL have developed multiple butt and fillet procedures to weld all of these materials and here they are put in practice for a recent hi spec fabrication for our valued client.

With over 20 years in business as precision specialist welders and fabricators, we would love to support you on your next subsea or offshore project.

316 Stainless Steel Fabrication

SWEL specialise in precision specialist welding and fabrications for industrial stainless steels. Such as this Grade 316 piece for a recent client.

316 stainless steel is an austenitic stainless steel alloy, known for its enhanced resistance to corrosion, particularly in environments containing chlorides.

The key difference between 316 and the more common 304 grade is the addition of 2–3% molybdenum, which provides superior resistance to pitting and crevice corrosion.

SWEL have numerous weld procedures for all austenitic, martensitic and duplex stainless steels and a team highly skilled fabricators, producing quality work to tight deadlines, complete with concise manufacturing record books.

If your next project requires a precision specialist stainless steel welder and fabricator, speak to us at SWEL.

Hastelloy C-276 Spools

These particular Hastelloy C-276 spools were for a national clients new build plant as part of a pipework contract.

Hastelloy C-276 is one of only a few materials resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions. The key with this procedure is dramatically low interpass temperatures.

Whatever you industry, whatever you precision welding requirements, SWEL can support your next project.

Super Duplex Welding

SWEL specialise in precision specialist welding for materials such as Super Duplex.

Super Duplex is a high-performance stainless steel with a mixed microstructure of austenite and ferrite. It has high yield strength and superior corrosion resistance to other stainless steels, making it ideal for aggressive environments in applications like oil and gas, chemical processing, and marine engineering.

SWEL have numerous weld procedures and highly skilled fabricators, producing quality work to tight deadlines, complete with concise manufacturing record books.

With over 20 years in business as precision specialist welders, we would love to support you on your next subsea, offshore or oil and gas project.

Copper Pump Rotor

Since our founding in 2005, we have formed many longstanding industry relationships, such as this client partnership in the power generation industry, which goes back over 20 years.

SWEL are experts in specialist welding techniques, such as silver soldering, and this copper pump rotor was finalised as part of this ongoing contract agreement.

SWEL have a rich and varied history supporting the power generation industry, supporting with aspects such as:-

Weld repair and reclamation of turbine blades.
Site services for weld repairs, pipe work, ductwork and metal fabrication.

S690 QL Conical Fabrication

SWEL produce specialist steel fabrications for the subsea industry.

This complex conical fabrication, was machined in high strength S690 QL steel to support a customer in the subsea sector.

SWEL have numerous weld procedures and highly skilled fabricators, producing quality work to tight deadline, complete with concise manufacturing record books.

With over 20 years in business as precision specialist welders, we would love to support you on your next subsea, offshore or oil and gas project.

Indudtrial Bolt Tensioning

Sometimes thought of as extremely difficult to weld, especially in the T condition, SWEL have successfully developed procedures to weld EN24T

This piece was produced to support the industrial bolt tensioning industry.

Contact our welding engineers to discuss your specialist welding requirements.

Heat Exchanger

Heat exchanger and boiler weld repair and manufacture.

This heat exchanger was manufactured from 316 stainless steel in accordance with ASME 1X.

SWEL Group carry out all boiler and heat exchanger repair and manufacture works nationally. Constructed to the highest of quality often to strict client deadline.

Offshore Fabrication

Of the many industrial sectors we support, SWEL provide specialist welding and fabrications services to the offshore industry.

S355 J2 is the go to steel for the offshore world, mainly for its high yield stress to impact resistance ratio.

The difficulty of a machined fabrication, is the control of distortion prior to machining. Distribution of welding and the age old planned wander come into their own as a technique to hold dimensional accuracy.

SWEL have over 65 qualified weld procedures and offer total traceability and documentation.

Here’s a 650kg fab we fabricated and machined for one of our offshore customers.
