Laser Beam Submerged Arc Hybrid Welding

Physics Procedia, 2011
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 combination with the energy efficient submerged arc process improves the degassing and reduces the tendency to pore formation.

Special Submerged Arc Welding of Steel

Journal of the Japan Welding Society, 1959
Coated electrodes were laid down along weld seams, over which granular flux was heaped, and arc welding was performed automatically. Coated electrodes used are of the types D4301 (ilmenite), D4312 (rutile), D4313 (rutile), D4316 (lime basic) and D4320 (iron oxide).

Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

Optimal control of the heave motion of marine cable subsea-unit systems [PDF]

, 1995
One of the key problems associated with subsea operations involving tethered subsea units is the motions of support vessels on the ocean surface which can be transmitted to the subsea unit through the cable and increase the tension.
