A Study on Process Characteristics and Performance of Hot Wire Gas Tungsten Arc Welding Process for High Temperature Materials [PDF]

open access: yesMaterials Research, 2016
Hot wire gas tungsten arc welding (HW-GTAW) process is the one where the filler wire is pre-heated close to its melting point before it is fed in to the arc.

A Lensed Arc in the Low Redshift Cluster Abell 2124

open access: yes, 1998
We report the discovery of an arc-like object 27" from the center of the cD galaxy in the redshift $z=0.066$ cluster A2124. Observations with the Keck II telescope reveal that the object is a background galaxy at $z=0.573$, apparently lensed into an arc ...

Sensor Fusion to Estimate the Depth and Width of the Weld Bead in Real Time in GMAW Processes

open access: yesSensors, 2018
The arc welding process is widely used in industry but its automatic control is limited by the difficulty in measuring the weld bead geometry and closing the control loop on the arc, which has adverse environmental conditions.
