Environmentally responsible engineering British Metal Treatments (BMT), part of the AJT Engineering group, is offering an environmentally responsible material reclaim service to help companies repair and reconfigure engineering components. The company’s skilled workforce can carry out high quality reclamation work on everything from mandrels and sleeves to actuator cylinders, valves and couplings. The workforce at BMT has undergone extensive training, both in-house and externally through the Institute of Materials Finishing, in areas such as electroplating, correct current calculation, deposition applications and the unique process routes for specific substrates.

AJT managing director Kenneth Gauld said, “The deposition process is complex and the knowledge and expertise required by our depositors is of considerable note. Through reclamation, we can prevent the need for complete manufacture, which in turn lessens the environmental impact.” The company is able to carry out tailored, turnkey projects, as well as providing technical support throughout the surface treatment sector, and can assist with any environmental or health and safety concerns at project inception. The BMT plant specialises in electro- chemical deposition techniques, particularly with chromium and nickel, and electroless nickel plating (ENP). It also offers in-house machining and grinding, and carries out all surface work before and after the plating processing. repeatable, X-ray quality welds. The K-TIG process involves a specially controlled high current arc that opens a full penetration keyhole in the joint between the two surfaces to be welded. It provides high stability and operates over a wide range of welding currents and travel speeds. It was developed by the Australian Government’s Commonwealth Scientific & Industrial Research Organisation (CSIRO). K-TIG welds meet US, European and Australasian welding standards, and have been subjected to exhaustive Lloyd’s-witnessed and certified testing. K-TIG has exported to 17 countries.

The company recently completed an extensive and complex project to repair and reclaim a cylinder clamp body, traditionally discarded following use. The team isolated the area to be treated with 0.07" nickel, before machining work was carried out and finally hard chrome plating (HCP) was applied. Having a fully equipped machine shop within the facility complements all surface treatments and realises enhanced delivery performance. Reclamation is a key factor in the circu- lar economy and is seen as a sustain- able and environmentally responsible method of reducing waste and re-using valuable materials. It eliminates the need to manufacture new components from scratch, and so reduces environ- mental impact. K-TIG is a welding technology company based in South Australia. The company claims that its new high speed, full penetration GTAW welding technology has productivity, cost and quality advantages over existing processes, particularly in stainless steels and other corrosion-resistant materials. K-TIG welds are performed in a single, full penetration pass up to 13mm (½") in stainless, duplex, super duplex, Hastelloy, Inconel, Nimonic and other corrosion-resistant materials and super alloys, and up to 16mm ( 5 / 8 ") in titanium, zirconium and other reactive metals. The process requires no edge bevelling and no wire (although wire can easily be added). It uses as little as ten per cent of the gas normally required, and produces
