Optimización del proceso de soldadura GMAW de uniones a tope de la aleación AA 6063-T5 basada en la metodología de superficie de respuesta y en la geometría del cordón de soldadura

Revista de Metalurgia, 2012
La geometría de los cordones de soldadura es caracterizada por el sobreespesor, la anchura y la penetración. Estos valores son indicadores del comportamiento de la unión soldada por lo que pueden considerarse como factores de control del proceso.

Reduction of Energy Input in Wire Arc Additive Manufacturing (WAAM) with Gas Metal Arc Welding (GMAW)

Materials, 2020
Wire arc additive manufacturing (WAAM) by gas metal arc welding (GMAW) is a suitable option for the production of large volume metal parts. The main challenge is the high and periodic heat input of the arc on the generated layers, which directly affects ...

MIG gas shielding : Economic savings without detriment to quality

, 2011
Over the years a number of claims have been made related to potential savings of the shielding gas used in the MIG process. A number of work streams have been set up to consider such areas from a technical and economic standpoint. The use of small helium

Evaluation of Heat Sources for the Simulation of the Temperature Distribution in Gas Metal Arc Welded Joints

Metals, 2019
Residual stresses can affect both the static strength and the fatigue endurance of welded joints. Residual stresses can be assessed by numerical simulation; however, the simulation of the welding process is a complex task that requires knowledge of ...

Effect of plasma welding current on heat source penetration ability of plasma-GMAW hybrid welding

The International Journal of Advanced Manufacturing Technology, 2022
The weld penetration under different plasma welding currents was compared in the plasma-gas metal arc welding (GMAW) hybrid welding of aluminum alloy. When the plasma welding current was lower than 150 A, the hybrid welding penetration was greater than ...

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, EarlyView.
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.
