Underwater Welding

Commercial Divers Underwater Welding & Broco Cutting

Gray Diving is able to offer a complete range of underwater welding and cutting procedures.

While most diving contractors will offer underwater welding and cutting services, very few will be able to provide certifiable welds or the precision cutting that is sometimes required. At Gray Diving our policy of employing tradesman divers means that only qualified metal fabricators / welders are used to carry out significant underwater welding and cutting projects.

Prior to the commencement of any welding program, all personnel to be engaged on the project as welder-divers will undergo a weld coding.

This is carried out using the same materials, electrodes, positional requirements and, where possible, under the same environmental conditions particular to the project. The resulting test coupons are released to the client for testing or alternatively in-house testing and examination will be carried out with results made available to the client.

To further encourage client participation and monitoring G.D.S. has established a wet welding training tank in our Caringbah workshop, with direct view ports and closed circuit video.

Gray Diving personnel are members of the W.T.I.A. (Welding Technology Institute of Australia) and A.W.S (American Welding Society).
