Low‐Voltage Pulsed GMA‐AM Application for Controlling Heat Input and Improving Deposition Quality of 309LSi Multilayered Structures

steel research international, EarlyView.
This manuscript presents a study on the effects of parameter control of low‐voltage pulsed‐GMA‐AM application for producing 309LSi multilayered build‐ups, which can simultaneously lead to reduced heat input up to 32.1%, enable pulsed‐spray transfer, provide stable depositing conditions and preserve dimensional consistency, favoring fabrication of a 114‐

Numerical Modeling Of GMAW ARC [PDF]

, 2007
A comprehensive model has been developed to simulate the transient, coupled transport phenomena occurring during a gas metal arc welding process. This includes the arc plasma; melting of the electrode; droplet formation, detachment, transfer, and impingement onto the workpiece; and weld pool fluid flow and dynamics.

Dynamic behavior of the weld pool in stationary GMAW [PDF]

EPJ Web of Conferences, 2010
Becaus hump formation limits welding productivity, better understanding of the humping phenomena during the welding process is needed to access process modifications that decrease the tendency to hump formation and then allow higher welding productivity.

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Effects of welding parameters on percentage dilution and mechanical properties in welded joints of ultra-high hardness armour steels [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
This study investigates the effects of Gas Metal Arc Welding (GMAW) parameters—specifically welding speed and stickout— on the dilution and mechanical properties of welded joints composed of ultra-high hardness quenched and tempered (UHH-Q&T) armor steel

Fatigue Assessment of Welded Joints Subjected to Multiaxial Loading Conditions through the Effective Critical Plane Approach

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 5048-5064, November 2026.
ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

A Methodology to Parameterize Wire + Arc Additive Manufacturing: A Case Study for Wall Quality Analysis

Journal of Manufacturing and Materials Processing, 2020
The objective of this work was the development of a methodology to parametrize wire + arc additive manufacturing (WAAM), aiming dimension repeatability, and tolerances. Parametrization of WAAM is a difficult task, because multiple parameters are involved

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, Volume 97, Issue 10, Page 5079-5089, October 2026.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Optimization of Source-Wire-Gas Systems for Efficient Robot Welding [PDF]

International Journal for Simulation and Multidisciplinary Design Optimization, 2010
GMAW (Gas-Metal-Arc-Welding) as the last of main technologies, yet based for a most part on manual (semiautomatic) work, is gradually automated. But traditional advances of weld design, technology and quality assurance is not essentially changing.
