The core competence of the company still remains welding but as the company has continued it has added further associated engineering activities in order to service customer needs, including: conventional turning and milling, CNC turning /milling and assistance with engineering design and solid modelling CAD. The company has also progressed to successfully undertaking significant manufacturing projects. Welding Capabilities. The principal welding processes used by the company are TIG, MIG and MMA The Company welds a large range of materials and the following is a broad outline of the capabilities. A wide range of carbon and carbon alloy steels A wide range of Stainless Steels A wide range of Aluminum Alloys A wide range of other materials for example:- Aluminum Bronze, Cast Iron, Magnesium, Copper and Titanium. Hard facing is also done. The standards most commonly worked to are AWS, ASME and PD5500. The Company has a range of qualifications but if additional qualifications are required the Company will collaborate were practical in obtaining the requisite qualifications. The Company’s wide range of welding techniques, combined with the ability to work with a wide range of materials, has enabled it to render specialist services on products ranging from light through to heavy engineering. Whilst much of the welding undertaken is done in the workshop, the company also works extensively on sites undertaking a wide variety of repairs. Installations of either new or replacement equipment are undertaken. Many of the sites require positional welding in difficult conditions and the high level of welding competence of Trio delivers quality results in such circumstances.
