Additive manufacturing based on gas metal arc welding (GMAW) is gaining increasing popularity as the process allows fabrication of fully dense parts with high material efficiencies and deposition rates. This paper aims at studying forming characteristics of multi-layer single-pass parts. Influences of arc current, deposit velocity, and heat input on layer formation were analyzed by using a passive vision sensor. Based on the results, the arc current has the greatest effect on the forming appearance, and a better understanding of the forming characteristics and process specification interval in multi-layer single-pass GMAW-based additive manufacturing can be obtained. Some newly improved GMAW methods were considered to improve deposition rates in multi-layer single-pass additive manufacturing process.

“…As the low current and the construction of the plasma torch, the micro plasma beam is formed with a diameter of Ф0.6mm when the compressed air was ionized by the high voltage. Then it was divided again into lots of [14]. Due to the thermal expansion coefficient of the contaminant and rust is lower than the metal matrix, they were melting or gasification to be removed firstly when the metal surface was heat up to a certain temperature.…”

A metal surface finishing method by micro plasma beam irradiation was examined and presented in this study. Grey cast iron was used as the experimental material to examine the finishing effect by the micro plasma beam. This experimental setup consists of a compressed air system, a plasma torch and a power supply. The compressed gas was ignited by high voltage direct current pulsed gas discharge and facilitated the generation of plasma, as well as a plasma beam with a maximum diameter of 0.6 mm was used for finishing the metal surface instantly. The experimental results show that it was possible to remove the peak points which exist on the metal surface. It was showed clearly that after the irradiation by the micro plasma beam, the initial rusty and rough surface becomes a clean and smooth surface under a proper finishing condition.

“…This solution makes it possible to get rid of problems connected to a low productivity of the available methods, a high price of the equipment used, a limited range of materials used, which are typical for the traditional source material during additive formation, i.e. powder systems melted with a powerful heat source [13][14][15]. The prospects of developing the wire-based formation technologies are great, and they have not yet been revealed in the world.…”

Prospects of one of unconventional research areas aimed at improving additive technologies have been described. The key aspect of the proposed technology is the formation of multilayered homogeneous materials in vacuum using electric arc as a heating source, as well as using a solid metal wire as a filler metal. It is shown that this approach, compared to the available solutions applied in the global industrial production practices, will serve to increase productivity related to forming layerwise materials, as well as to resolve a number of disadvantages of the available equipment used for additive technologies implementation.
