Gridweld has been set-up to provide orbital welding systems that embraces all the features of existing equipment in the marketplace with new technology to provide faster, lighter, and more efficient machines which can be set up and operated with ease by the welding crew.
At our premises in the West Midlands we design, manufacture, and assemble all parts with the minimum of sub-contract intervention or support thereby ensuring the quality of our products and enabling speed of implementing any changes if required in the future.
Scorpion is Gridweld's new advanced automatic pipeline welding robot. We have carried out extensive research and development and spent many hours refining Scorpion before launching the product onto the market.
Scorpion's performance and durability within various environments has been verified along with the quality of weld using ultrasonic testing for the pipeline construction industry through AMK Inspection Ltd.
One key advantage of the machine is its weight - it's light and this enables ease of use when attaching to the band.
Independent dwell is of benefit and enables the operator to weld steep gradients and accommodate pipe of differing wall thicknesses.
Scorpions insulated shroud and shield assembly ensures tip replacement is minimal and provides good gas flow.
Welding passes can be re-selected whilst welding i.e. pass 1 to pass 2 with no pause.

| Pre & Post Purge | 1000 ms maximum |
We can offer in-house or on-site operator and technician training and assistance with start-up or on-site supervision as well as offering troubleshooting of any weld quality or operator problems.
Welding procedures can be developed for any new applications that a client may have either in-house or in the field.
We can organise and run any pipeline worldwide and can provide the welding equipment and consumables to do so including bands for the Scorpion machine.
We can arrange for the inspection of any weld joint to industry standards and our Welding Director is able to conduct tests on different manufacturers wire as carried out for ESAB and Bohler welding.
Our aim is to provide a quick response to requests for spares and to support the front line welding crew.

The three directors of Gridweld have many years of experience in their related fields.
Roger has 30 years experience in precision engineering and efficient manufacturing processes including design and manufacture of bespoke fixtures and tooling.
Dominick has over 40 years experience in the pipeline welding industry and has worked on a vast range of projects for major contractors.
Dominick has managed the welding operations on pipelines worldwide. The pipelines welded cover in excess of 2000 miles. He has written and performed procedures to specifications and trained welders on-site.
Listed below are some of the major pipeline welding projects Dominick has been involved with over the years:
Comet-Ridge to Wallumbilla 120km for Murphy Pipe & Civil using 12 of our Scorpion bugs - welded in record time.
Murphy Pipe and Civil crews reset company record book on welding using OUR Scorpion welding bug. Read about it here.
Gridweld's 'Scorpion' automated welding system is presently welding 10 km’s of 20” 25mm with Murphy pipelines in the Middlesbrough area.
