Processing characteristics of Ni-WC MMC weld cladding by various types of GMAW

Materials and Manufacturing Processes
GMAW (gas metal arc welding) with various transfer modes, including GMAW-G (GMAW with globular transfer), GMAW-S (GMAW with short-circuit transfer), GMAW-P (pulsed GMAW), and CMT (cold metal transfer), were engaged for depositing overlays of nickel ...

Dynamic modeling of GMAW process

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
A model has been developed correlating the anode temperature profile with the dynamic melting rate in gas metal arc welding. Components of this model are identified as the electrode melting rate, temperature-dependent resistivity of electrode and arc voltage.

Planning the GMAW process by constraint propagation

Journal of Intelligent Manufacturing, 1997
Although the gas metal arc welding (GMAW) process is widely used for joining metals, its planning is still a cumbersome task. The planning procedure involves many complex interrelationships among the process variables and depends heavily on empirical knowledge.

A simplified voltage model in GMAW

Welding in the World, 2020
The relation between the voltage and the arc length in gas metal arc welding (GMAW) is an important characteristic. It determines the power transfer to a large extent, and its knowledge allows the control of the process. However, the voltage depends on a complex distribution of the electric conductivity along the current path and does not depend on the

Arc initiation in aluminium GMAW

Welding International, 2010
The use of pulsed current for MIG welding of aluminium, despite being one of the most recommended technologies, due to its better results, presents difficulties at the start of the process, principally in regard to arc initiation. With the aim of developing a more suitable process of arc initiation, two new techniques were studied: the first based on ...
