In the present work, an attempt has been made to use the grey-based fuzzy logic method to solve correlated multiple response optimization problems in the field of flux cored arc welding. This approach converts the complex multiple objectives into a single grey-fuzzy reasoning grade. Based on the grey-fuzzy reasoning grade, optimum parameters are identified. The significant contributions of para...

In this paper, we present a comparison between the older DSTV file format and the newer version of the IFC standard, dedicating special attention of its impact in the robotization of welding and cutting processes in the steel structure fabrication industry. In the last decade, we have seen in this industry a significant increase in the request for automation. These new requirements are imposed ...

This thesis deals with the problem of seam detection for robotic laser welding applications. Within the Mechanical Automation laboratory of the Engineering Technology faculty, a compact, lightweight and multi-purpose welding head is developed. The integrated welding head is attached to a robot and should be able to detect seams, learn trajectories, do the laser welding and inspect the welds. A ...

The welding process is used by many manufacture companies and due to this wide application many studies have been carried out in order to improve the quality and to reduce the cost of welded components. Part of the overheads is employed in final inspection, which begins with visual inspection, followed by destructive and nondestructive testing techniques. In addition to cost raise, final inspec...

The manual process of manufacturing the welding electrode takes more time and work. It also occupies more space for the control panel with the installation of PLC in the welding electrode manufacturing control panel the size of the panel is reduced to the great extent. It has reduced the cost of the panel and has increased the rate of the production. Here the entire process of electrode manufac...

1 Abhijit Nagchaudhuri, University of Maryland Eastern Shore, Princess Anne, MD. 21853-1299, [email protected] Abstract Robots and numerically controlled machines allow easy reprogramming capability to adapt to varying task requirements and hence have found extensive use in manufacturing automation in factories. Although programmable robots have provided some degree of flexibility in ...

Robotic welding processes are widely used in manufacturing and especially in the automotive industry. Quality problems in the automation of this process became a leading cause of attention by manufacturers and researchers interested in improving these processes. Within the wide range of automated welding processes that exist in the industry, the most used is the Gas Metal Arc Welding Process (G...
