Control 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...
متن کاملStudy on Evaluation Method of Aluminum alloy Pulse MIG Welding Stability Based on Arc Voltage Probability Density
Bring forward a new analytical method in order to evaluate the stability of the process of aluminum alloy pulsed MIG welding. The ratio of the first and the second peak in arc voltage signal probability density was selected to evaluate aluminum alloy pulse MIG welding stability. By calculating the arc voltage signal probability density from 80 sets of welding experiments, the ratio of the two p...
متن کاملRetinal burns from MIG-welding arcs.
SIR, I read the article by G P H Brittain' on retinal burns caused by exposure to MIG-welding arcs with great interest. I had not seen any cases in Australia and so I was very interested to study the illustrations. Two cases were described. The first case was illustrated in Fig. 2 but I could not see the 'small dark lesion above each fovea' said to be present. The second case is illustrated in ...
