System maintains constant penetration during fusion welding [PDF]
, 1967 Servo system senses variations in fusion welding process, and adjusts the control parameters to compensate for them. The system assumes a correlation between uniform weld penetration and temperature gradients near the molten puddle.

Welding Current and Nitrogen Content of Weld Metal (Report 1)
Journal of the Japan Welding Society, 1973 Effect of welding current and sampling method on the nitrogen content of weld metals in nitrogen and air atmospheres using a pure iron electrode wire was studied.Three methods i.e. depositing on a mild steel plate, rotating copper disk and water cooled copper block were used for sampling at different current levels.The main results obtained are ...

Current trends in welding flux development
Nigerian Journal of Technology, 2021 Welding flux makes significant contribution to weld-metal quality, productivity of welding process and rapid deployment of new materials. Deployment of new materials has been hampered because of lengthy trial-and-test experiments and paucity of methodology for modelling and optimisation in the traditional welding flux development ...

Advanced Healthcare Materials, EarlyView.Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.
