TANDEM ROBOTIC FCAW WELDING

Robotic Shielded Metal Arc Welding

In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...

A novel friction stir welding robotic platform: welding polymeric materials

The relevance, importance and presence of industrial robots in manufacturing have increased over the years, with applications in diverse new and nontraditional manufacturing processes. This paper presents the complete concept and design of a novel friction stir welding (FSW) robotic platform for welding polymeric materials. It was conceived to have a number of advantages over common FSW machine...

Intelligent Control of Modular Robotic Welding Cell

Although robotic machines are routinely used for welding, such machines do not normally incorporate intelligent capabilities. We are studying the general problem of formulating usable levels of intelligence into welding machines. From our perspective, an intelligent machine should: incorporate knowledge of the welding process, know if the process is operating correctly, know if the weld it is m...

Qualification of a Robotic Pipeline Orbital Welding

This work presents the procedure qualification for pipeline orbital welding using a robotic system. The system has four degrees of freedom, which allow the controlling of the stick out, the travel speed, the torch angle and the positioning. The arc voltage and welding current are also controlled during the welding, although the system uses a conventional power source. With the system it is poss...
