Welding quality and sustainability of alternative LPG valve boss welding processes [PDF]
This work aimed to evaluate the welding quality and the sustainability of an automatic metal active gas with mixing gases (MAG-M) process for welding the valve boss on liquefied petroleum gas (LPG) upper cylinder half, in comparison to the presently ...

Submerged arc welding of heavy plate [PDF]
The submerged arc process is particularly suitable for heavy plate welding because of its ability to combine very high deposit rates along with excellent quality. It does these things without the smoke and spatter often accompanying other processes.

SUBMERGED WELDING WITH PULS ARC
The features of submerged arc welding with a pulsed arc (SWPA) have been studied. It is shown that an appropriate choice of SWPA parameters makes it possible to change the flows distribution in the weld pool and the thermal cycle characteristics of welding. With a constant heat welding input, the welds made by SWPA have a 20 ... 25% greater penetration

This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Multiwire submerged arc welding of steel structures [PDF]
The assembly of large structures made out of thick steel plates requires a welding process by which multiple wires can be used simultaneously. To reproduce these industrial processes in a research environment, OCAS has invested in a multiwire submerged ...

Correlation between Arc Phenomena and Welding Parameters in Submerged-Arc Welding
In submerged arc welding, the direction of arc column and the position of molten metal in the crater have been examined using a X-ray image intensifier TV system in order to regulate weld bead shape by controlling welding parameters.Arcs are classified into the open and buried arcs depending on the position of electrode tip to the plate surface.

Friction stir welding of thin DH36 steel plate [PDF]
A series of 4, 6 and 8 mm DH36 steel welds were produced using optimum conditions for friction stir welding (FSW). Comparator welds in the same thickness from the same plates were produced using a single sided single pass process submerged arc welds (SAW)

Boron‐Doped Nano‐Crystalline Coated Carbon Fibers for Phasic Dopamine Sensing
This uniform coating presents a mix of graphitic and diamond‐like carbon to create a mechanically and electrically robust alternative for the electrochemical detection of dopamine. The electrodes in this work possess the equivalent sensitivity to the state‐of‐the‐art FSCV dopamine detecting electrodes, whilst demonstrating an ability to withstand ...
