Improvement of Welding Penetration in MIG Welding

, 2018
This investigation is to review the technique of using ACTIVATED FLUX for optimum penetration & hardness of MIG welding. Two kind of fluxes, Al2O3 and Fe2O3 used on a mild steel plates of 50mm x 50mm square and 8 mm thick. The fluxes used were packed in powered form & applied through a thin layer of flux.

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming

Advanced Engineering Materials, Volume 27, Issue 16, August 2025.
Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Time–Frequency Feature Extraction of Acoustic Emission Signals in Aluminum Alloy MIG Welding Process Based on SST and PCA

IEEE Access, 2019
The acoustic emission (AE) signal is weak due to the coupling and intersecting coexistence of other disturbance components in aluminum alloy metal inert-gas welding (MIG) process.

Occupationally Relevant Zinc‐ and Copper‐Containing Metal Fumes Inhibit Human THP‐1 Macrophage TNF and IL‐6 Responses to Bacterial Stimuli

Global Challenges, Volume 9, Issue 5, May 2025.
Metal workers have an increased risk of severe pneumonia due to metal fume exposure. In this study, zinc oxide (ZnO) and copper oxide (CuO) particles are found to inhibit specific anti‐bacterial macrophage responses, which may substantially contribute to impaired lung immunity.

An investigation on plasma-MIG hybrid welding process of thick plate aluminum

Journal of Advanced Joining Processes
Plasma-Metal Inert Gas (MIG) hybrid welding was employed to carry out bead on plate welding of an aluminum alloy A5052. The plasma arc was ignited to form a keyhole, and a series of welding systems were developed starting with MIG welding. The convective

Radial Deposition for Mechanical Bonding of Dissimilar Metals in Wire Arc Additive Manufacturing

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
Concentric radial deposition patterns are used in a wire‐arc directed energy deposition system to produce a layer‐by‐layer in situ bimetallic coupling between AA5356 and SS308L. The additively generated mechanical bond is produced by residual pressure, created by different thermal expansion coefficients between the concentric material bands during ...
