Optimising the laser-welded butt-joints of medium carbon steel using RSM [PDF]

, 2005
The optimization capabilities in design-expert software were used to optimise the keyhole parameters (i.e. maximize penetration (P) and minimise the heat input, width of welded zone, (W) and width of heat affected zone (WHAZ)) in CW CO2 laser butt ...

Large‐Scale Submarine Sediment Waves at Macauley Caldera Volcano: In Situ Evidence of High‐Flux, Syn‐Eruptive Submarine Transport

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed, submarine sediment waves. The sediment waves are large (>100 m high, 1.5 km wide, tens of km long)

EXPERIMENTAL STUDY OF WELDING RESIDUAL STRESS OF HIGH-STRENGTH SHIPBUILDING STEEL

Brodogradnja, 2019
Ships are large welded structures. Welding residual stress (WRS) significantly impacts the mechanical properties of the structure. The plate and cylinder models welded by electrode welding (EW) and submerged arc welding (SAW) were designed to measure the

Laser Beam Submerged Arc Hybrid Welding

Physics Procedia, 2012
AbstractThe laser beam-submerged arc hybrid welding method originates from the knowledge that, with increasing penetration depth, the laser beam process has a tendency to pore formation in the lower weld regions. The coupling with the energy-efficient submerged-arc process improves degassing and reduces the tendency to pore formation.

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Synthesis of compositionally‐complex materials is limited by immiscibility of elements. Nonequilibrium synthesis methods reviewed here use ultrafast heating and cooling to overcome this limitation, creating metastable solid solutions and high‐entropy nanomaterials.
