Subcontract fabrication and welding project completed on customers premises. We were contracted to produce six identical chassis for human powered vehicle with positions for eight riders and one driver. The chassis measured in excess of 5.5 meters by just over 3m wide. Constructed using a variety of extrusion profiles in 6082-T6 aluminium using the TIG welding process.
These chassis were of a double deck space frame construction with multiple supports and trusses. There was a requirement for these to be flat, to within 5mm corner to corner to ensure that the final assembly including the wheels would keep all four wheels in contact with the ground as there was no suspension on this design.
The nature of this project required accurate cutting and mitring of the tube to retain a close tolerance on the final dimensions and flatness. Using careful levelling and laying out of tressels, ensured a high-quality result.
In addition to the welding and fabrication of the 6 chassis, I also completed the mechanical fit out of 2 units with the business owner. The remaining 4 units were stored for later use.
During the contract, there was a requirement for ongoing welding repairs on several chassis which were fabricated by previous employees.
