Weld Penetration Control with Radiographic Feedback on Weld Pool Depression
NDT & 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.

Effect of welding speed on the microstructure and hardness distribution of laser beam welding joints
工程科学学报, 2015 Nuclear grade stainless steel welding joints were prepared by laser beam welding (LBW) at different welding speeds. Optical microscopy and scanning electron microscopy were subsequently used to study the weld penetration ratio, δ/γ ratio, micro structure,

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