Weld Procedure Development

We have the expertise and experience to develop unique solutions for your welding requirements.

Our range of expertise covers all aspects of arc welding and a wide range of applications, among which are orbital welding, structural welding, overlay welding, hard facing and weld repairs. This can involve developing welding parameters for new materials or combination of materials and the automation of the process either for onsite or off site welding.

Metallurgical Analysis

We have the experience to be able to advise on the best test methods for your materials and components, and if necessary the expertise to help you interpret your results and apply them to your materials problems.

Welding

The advances in welding technology over the past 20 years have been such that continual assessment is a priority within the company.

We ensure that our skilled welders are fully conversant with the latest industry developments and are technically qualified to international standards.

Our highly qualified team have particular expertise in working with reactive metals, high nickel alloys and stainless steels, all of which are utilised for their resistance to corrosion and/or elevated temperature.

Welding Processes

  • MIG
  • TIG
  • MMA
  • Plasma
  • Automatic front face tube to tubeplate
  • Automatic back face tube to tubeplate
  • Automatic orbital
  • Automatic weld overlay

Orbital Welding

We have world class expertise in the use of computer controlled Orbital Welding systems. Orbital Welding improves quality and productivity, and is used in many applications where manual welding would not be feasible.

Orbital Welding has many applications. Some recent examples include:

  • Installation of pharmaceutical process piping
  • Heat exchanger tube to tubeplate welding
  • Valve seat repair
  • On site shaft repair
  • Welding of hygienic piping systems
  • Repair of the internal surface of reactor tubes
  • Welding of small bore instrumentation piping
  • Weld Development

Weld Overlay

We have many years experience in the application of corrosion resistant weld overlay- either as a cost effective alternative to a solid structure or as a repair procedure.

A wide range of applications can benefit from this approach including pipelines, flanges, valves, vessels and offshore equipment.
