Arc Welding Automation
It is very well known that the use of robotics in the industry increases productivity and quality in many aspects. It is also well known that some adjustments have to be made to grant payback for the investment and to reach the expected results. Today, the robotization is known as an alternate technique for production, increasing qualitative and quantitative competence of its industries. One po...
متن کاملArc Welding Robot Automation Systems
Robot automation systems are rapidly taking the place of the human work force. One of the benefits is that this change provides the human work force with the time to spend on more creative tasks. The highest population of robots is in spot welding, spray painting, material handling, and arc welding. Spot welding and spray painting applications are mostly in the automotive industry. However, arc...
متن کاملControl of pulsed gas metal arc welding
This paper presents a control system for manual pulsed Gas Metal Arc Welding (GMAW). This system consists of a current controller, which makes it possible to shape the current during welding, and two important components, which are the key issues discussed in this paper. These components include an arc length controller and a metal transfer controller. The arc length controller is based on a no...
متن کاملArc Shape Characteristics with Ultra-High-Frequency Pulsed Arc Welding
Arc plasma possesses a constriction phenomenon with a pulsed current. The constriction is created by the Lorentz force, the radial electromagnetic force during arc welding, which determines the energy distribution of the arc plasma. Welding experiments were carried out with ultra-high-frequency pulsed arc welding (UHFP-AW). Ultra-high-speed camera observations were produced for arc surveillance...
متن کاملPerspective on Double Pulsed Gas Metal Arc Welding
Aluminum alloy welding suffers from problems such as solidification cracking and hydrogen-induced porosity, which are sufficiently severe to limit its potential applications. Because mitigated porosity incidence and solidification cracking are observed in aluminum welds using double pulsed gas metal arc welding (DP-GMAW), a comprehensive review of the mechanism is necessary, but absent from the...
