Study on output response of submerged arc welding process
Tehnički Vjesnik, 2017 Study on heat affected zone (HAZ) width is very essential for getting required weld quality. Minimization of HAZ width is urgent for high quality of weld. In present paper, an attempt has been made to find out relationship between process control factors

Arc Plasma Torch Modeling [PDF]
Journal of Thermal Spray Technology, (2009), Vol. 18, No. 5/6, pp.
728-752, 2013 Arc plasma torches are the primary components of various industrial thermal plasma processes involving plasma spraying, metal cutting and welding, thermal plasma CVD, metal melting and remelting, waste treatment and gas production. They are relatively simple devices whose operation implies intricate thermal, chemical, electrical, and fluid dynamics ...

The Impact of a Deep-Water Plunging Breaker on a Partially Submerged Cube [PDF]
Proceedings of the 30th Symposium on Naval Hydrodynamics, Hobart,
Tasmania, Australia, November 2014, 2017 The impact of a plunging breaker on a partially submerged cube is explored experimentally in a wave tank equipped with a programable wave maker. The experiments are conducted with the cube (dimension $L=30.48$ cm) positioned at one streamwise location relative to the wave maker and at three heights relative to the undisturbed water level.

Multi-Skein Invariants for Welded and Extended Welded Knots and Links [PDF]
arXiv, 2018 The theory of welded and extended welded knots is a generalization of classical knot theory. Welded (resp. extended welded) knot diagrams include virtual crossings (resp. virtual crossings and wen marks) and are equivalent under an extended set of Reidemeister-type moves.

Microwave roasting of agglomerated flux for submerged-arc welding
Green Processing and Synthesis, 2016 A microwave (MW) roasting experiment of agglomerated flux for submerged-arc welding was carried out. The MW heating characteristics of agglomerated flux and influence of roasting temperature on weld surface were investigated.

Effect of shielding gas composition and welding speed on autogenous welds of unalloyed tungsten plates [PDF]
arXiv, 2019 Tungsten usually exhibits poor weldability and marked brittleness at room temperature. This cause tungsten welds to be affected by the evolution of cracks along the weld bead, which can be eliminated by using a pre-heating step to reduce thermal straining.

Waste-based consumable for hardfacing by welding: a look from the Circular Economy
DynaIn the present work, the obtaining of a consumable for the restore parts by welding from the perspective of the circular economy is addressed, using industrial solid residuals (slag from steel production, graphite from fragments of electrodes of arc ...

Conformal weldings in the Loewner equation and Weil--Petersson quasislit-disks [PDF]
arXivA simple arc $\Gamma = \gamma(0, T]$, growing into the unit disk $\mathbb D$ from its boundary, generates a driving term $\xi$ and a conformal welding $\phi$ through the Loewner differential equation. When $\Gamma$ is the slit of a Weil--Petersson quasislit-disk $\mathbb D\setminus\Gamma$, the Loewner transform and its inverse $\Gamma \leftrightarrow ...
