Sub-Contract Orbital Welding

Small batch in-house orbital welding, using calibrated orbital welding equipment at our workshop, located in Sandy, North-East Bedfordshire. Where you need parts welded, rather than equipment supplied, we can run the job for you — to the same orbital welding standards we specify for our customers' own systems.

From one off prototype, or small number of welds as part of a larger job, to your need for extra production capacity, we can “Make It Happen”. Selecting the most appropriate orbital welding equipment for every task, the ability to design/manufacture any tooling required with all the right process tools, ensures our work is just a seamless extension to your production & manufacturing processes.

Typical Applications

The kind of jobs our service suits.

Our unique service offers quality, flexibility and reliability in today's business world, where increasing pressure to accommodate your customers' requirements and demands doesn't mean you need to increase your cap-ex budget or staff numbers for those small jobs. With our versatility we can accommodate 1-off design project samples to on-going repeating batch orders for production overflow, as and when required — giving you the confidence to meet your clients' expectations.

SituationHow We Help
Design & Project ManagementWe can work with your design/project team from the start. With CAD step files for weld heads, collet drawings together with our expert technical knowledge, you can ascertain any issues with your proposed orbital weld joints.
1-off Samples & Test PiecesFor situations when you may need to prove/qualify an orbital weld, or you have a customer requirement for just a few welds and either you don't have an orbital welding system or you don't want to break down vital production to spend the time setting up a system and creating the weld procedure and test pieces — let us take that pressure off your hands by sending the parts to us to weld for you.
Production PartsThis can be just a one-off small batch of orbital welding, or a regular production item that requires just a few welded parts every month or so but interrupts your production flow. We can help. Our experience in quality improvement processes means we can even help set up a kanban system/consignment stock, allowing you to focus on the larger business whilst keeping all your customers happy.
Offering A New ServiceGetting started in the orbital welding industry can be frightening, and that's just the investment cost of the equipment and process tools required before you even strike an arc. That's where we step in and help — you can add orbital welding as a service your company offers, but without the huge outlay of money. We can handle the small batch work on your behalf.
