18th International Conference on
Water Jetting
Gdansk, Poland: 13 - 15 September 2006

Introduction

The development of ultra high-pressure pumps in the early 1970s transformed the water jetting industry and led to the birth of this International Conference. Since the first conference, water jetting has grown into a mature industry with applications ranging from precision shaping of hard-to-machine materials, to environmentally friendly cleaning in many industries, the decommissioning of munitions and the removal of damaged flesh from severe wounds.

The addition of abrasives to waterjets has resulted in a cutting tool with unique capabilities, including the ability to cut without heat. Difficult cleaning problems have been solved using the technology, increasing the scope for recycling waste product. Decommissioning weapons, nuclear installations and oil and gas facilities in safety is now simpler. Fire fighting, rescue and other emergency service challenges are examples of some of the life-saving solutions achieved by water jetting.

Papers presented at this Conference, as outlined in the contents below, are available in a bound volume of proceedings from Mrs Marian Rolfe at BHR Group Limited.

BHR Group's Activities in Water Jetting

BHR Group's involvement in jetting began in 1972 with its first International Conference on this important technology. Since the early 1980's we have continued to investigate, research, develop and extend the capability of abrasive waterjet cutting processes - particularly for difficult, inaccessible and hazardous operations.

Particular emphasis has been placed on directly injected, abrasive suspension jet development, of which DIAJET is the prime example. BHR Group's Jetting Technology Centre team comprises of specialists working on a range of problems from underwater cutting to fine high beam precision machining of difficult materials and explosives decommissioning. Services to clients range from cutting trials to consultancy, research, and equipment supply. Complete cutting systems are developed and supplied for specific applications, along with technical support, training and back-up services.
