Those who cut corners when addressing this field of expertise are likely to regret it at a later stage. Selecting the correct technology for cutting, sawing and profiling is a complex matter, one in which the experts in this special feature are superbly informed and readily prepared. These experts cover the cutting spectrum from the ever popular sawing methods (rotary and band), lathe cutting, tube cut-off, rotary cutting, shear cutting and the advanced capabilities of laser cutting. Whether employing heat exchangers, tube bundles, or HVAC air coils, heat transfer itself is essentially a simple process. The movement of heat – via conduction, convection and radiation – enables such basic functions as staying warm and cooling down. But what is not simple is the expertise required to produce the tube to carry out this function. The products – made from materials such as high grade stainless steel, nickel alloy, glass lined steel, and copper – are all developed by specialists with the best knowledge of the application in hand. It is no surprise that exhibitors and visitors returning for the second, third and fourth-time to the Fabtech/AWS Welding Show, regard Chicago as one of their favourite destinations on the exhibition calendar. With over 1,000 exhibitors confirmed and more than 25,000 attendees expected, the biennial exhibition in Chicago has become a must-see event. This show feature provides essential information on Fabtech 2007, with a full exhibitor listing and selection of exhibitor profiles.
