Unique Group, a leading integrated subsea and offshore solution provider, with offices in Canada and the US, has announced that its On-Site Engineering division, through its Wellube brand, has partnered with KSB Group, a producer of valves, pumps and related systems, to offer a new service to its customers in the Middle East and Africa region. On-Site Spark Erosion is the latest addition to the division’s portfolio of services that include hot tapping & line stopping, on-site machining and safety valve testing among many others.
Spark erosion, also known as metal disintegration or electro discharge machining (EDM), is a technique that’s primarily used for tap, stud, bolt and drill removal or seized fasteners. An electrode, held in the head of the disintegrator, vibrates as it cuts while a coolant is pumped through the electrode to wash away the powdered metal. The technique chiefly employs electrical energy to remove metal from the work piece without creating any contact with it. The technique can also be used for marine and marine engine repairs.
