Welding & Precision Assembly Technician

Job Title: Welding & Precision Assembly Technician

Location: Whitney

We are seeking a skilled, practical technician to manufacture and assemble high-quality cryogenic products. This is a hands-on role with a strong emphasis on precision welding, soldering, brazing and mechanical assembly. The successful candidate will produce neat, accurate and leak-tight assemblies from stainless steel, copper and other materials, working carefully to engineering drawings and defined quality standards.

Experience in TIG welding, soft soldering and silver brazing/hard soldering would be highly advantageous. However, we will also consider candidates with strong mechanical aptitude, excellent attention to detail and a genuine willingness to learn specialist cryogenic manufacturing techniques.

• Manufacture and assemble nitrogen and helium transfer lines, vacuum components, pipework and other related cryogenic products.
• Carry out high-quality TIG welding, particularly on thin-wall stainless-steel components and tube assemblies.
• Perform accurate soft soldering and silver brazing/hard soldering on copper, brass, stainless steel and mixed-material assemblies.
• Assemble small, delicate and close-tolerance components with a high level of care and precision.
• Fit tubes, flanges, connectors, vacuum fittings and mechanical components in accordance with drawings and specifications.
• Use jigs, fixtures, gauges and measuring equipment to maintain alignment and dimensional accuracy.
• Carry out tube preparation, forming, bending and fitting where required.
• Inspect welds, soldered joints and completed assemblies for workmanship, conformity and leaks.
• Diagnose and rectify leaks, poor joints, misalignment and other manufacturing defects.
• Read and interpret engineering drawings, bills of materials and manufacturing instructions.
• Contribute to improvements in welding methods, assembly processes, tooling and product quality.

• Practical experience in welding, soldering, brazing, precision assembly or mechanical fabrication.
• Good hand skills and the ability to carry out detailed, controlled work.
• Strong mechanical fitting and assembly capability.
• Experience using workshop hand tools, power tools and measuring equipment.
• Ability to read and work from engineering drawings.
• Ability to work accurately with small components and close-tolerance assemblies.
• A methodical approach to joint preparation, assembly and inspection.
• Willingness to learn specialist cryogenic and vacuum manufacturing processes.

• TIG welding of stainless steel, particularly thin-wall tube and precision components.
• Soft soldering experience on copper and brass assemblies.
• Silver brazing or hard-soldering experience.
• Experience joining dissimilar metals.
• Tube fitting, tube bending and pipework fabrication experience.
• Experience with vacuum systems, cryogenic equipment, scientific instrumentation or high-vacuum components.
• Experience working in a precision engineering, aerospace, scientific, medical or specialist manufacturing environment.
• Comfortable working on both one-off and repeat production assemblies.
