WELDING AND CUTTING JOURNAL FOCUSES ON TRANSPORTATION AND PRODUCTIVITY

A new edition of Svetsaren, the journal of welding and cutting technology, is now available from ESAB. Features detailed technical articles and case studies relating to manual and automated welding and cutting in the transportation industries. In addition, the journal contains a round up of recent news from ESAB, plus new welding and cutting equipment.

One of the most interesting articles explains how the friction stir welding (FSW) process has been developed for use on geometries other than straight or circumferential joints. By mounting a FSW head on a heavy-duty standard industrial robot, ESAB has created a means by which FSW can be used on three-dimensional joints. Known as Rosio, the system can process aluminium alloys up to 5mm thick.

Given the state of the global economy and the particularly tough trading conditions in the transportation sector, Svetsaren features a number of productivity-related application stories. For example, Emcon Technologies Brazil has reduced cycle times by 25 per cent after switching to a ferritic stainless metal-cored wire for welding catalytic converters.

Other applications illustrate the benefits of robotic welding, the increased productivity offered by the Marathon Pac bulk wire system, how optimised welding processes can eliminate the need for manual finishing, and the advantages of using copper-free wire for robotic welding. Technical articles in this issue of Svetsaren include an explanation of the way in which Low Temperature Transformation (LTT) welding consumables can improve fatigue life.
