Weld Penetration Control with Radiographic Feedback on Weld Pool Depression

open access: yesNDT & E International, 1990
Recently [1,2], a method for remote arc weld process control using real-time radiography as a vision system was described. In this work information on weld quality extracted from real-time radiographic images was used in feedback to change welding conditions to maintain weld quality.

Experimental Study on Bearing Capacity of Welded Rectangular Section Members Under Different Weld Penetration Depths

open access: yes工程科学与技术, 2021
To effectively improve the durability of welded rectangular section members (WRSM) with tubular flange in long-span bridges, the use of weathering steel instead of ordinary steel was proposed. At the same time, to study the axial bearing capacity of WRSM

Effects of welding parameters on penetration depth in mild steels A-TIG welding [PDF]

open access: yesScientia Iranica, 2018
A-TIG welding is a welding method in which TIG welding is conducted by covering a thin layer of activating flux on the weld bead beforehand. The most benefit of this process is the gain in weld penetration depth. A-TIG welds were produced on mild steel plates with TiO2 flux.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Monitoring of aluminum alloy weld formation using TIG based on passive vision

open access: yesHanjie xuebao
During the butt-welding process of thin-plate aluminum alloys, the base metal was affected by fluctuations in the joint gap and uneven heating and heat dissipation. As a result, the weld was usually defective. A passive vision sensing method was selected
