Underwater Explosive Welding, Discussion Based on Weldable Window

AIP Conference Proceedings, 2006
A new method of underwater explosive welding is introduced and its possibilities are suggested. In the underwater explosive welding, a high explosive with detonation velocity of 7km/s is placed at an initial inclined angle to decrease the horizontal collision point velocity, which is one of the important parameters to achieve welding.

Accessing collision welding process window for titanium/copper welds with vaporizing foil actuators and grooved targets

Journal of Materials Processing Technology, 2014
Abstract A method for accurate, low-cost, lab-scale determination of the optimal collision angles and velocities for collision welding of a given combination of materials has been introduced. 0.508 mm thick grade 2 CP Ti sheets were launched at various velocities toward a Cu 110 target with grooves of angles ranging from 8° to 28°, machined on the ...

Management of heat in laser tissue welding using NIR cover window material

Lasers in Surgery and Medicine, 2011
AbstractBackgroundLaser tissue welding (LTW) is a novel method of surgical wound closure by the use of laser radiation to induce fusion of the biological tissues. Molecular dynamics associated with LTW is a result of thermal and non‐thermal mechanisms.ObjectivesThis research focuses exclusively on better heat management to reduce thermal damage of ...

Process Window for Nd:YAG Laser Welding of Super Duplex Stainless Steel

Journal of Russian Laser Research, 2018
Super duplex stainless steel (SDSS), an advanced duplex stainless steel with higher alloying concentration, is employed widely in acidic atmospheres. In this study, we make an attempt to develop a process window for the pulsed mode Nd:YAG laser welding of SDSS, as reference maps, to identify the range of process parameters viz., laser power, welding ...

DEVELOPMENT OF WELDING WINDOW FOR UNDERWATER AL – STEEL EXPLOSIVE CLADDING

Journal of Manufacturing Engineering
This study attempted analytical estimation of the welding domain for underwater explosive cladding of aluminium (Al 5052) - stainless steel (SS304). A welding window, an analytical estimation, can ascertain whether the interface is wavy-like or otherwise.

Non-vacuum electron beam welding through a plasma window

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
Abstract The plasma window is a novel apparatus that utilizes a stabilized plasma arc as interface between vacuum and atmosphere or pressurized targets without solid material. Additionally, the plasma has a lensing effect on charged particles. This feature enables beam focusing to very small spot sizes and overcoming beam dispersion due to scattering

CO2 laser welding of aluminum air spacers for insulated windows

ICALEO '82: Proceedings of the Materials Processing Symposium, 1982
Roll-formed aluminum or steel shapes are used as air spacers to separate glass in insulated windows. Industry required better product to provide possibility of automated handling of air spacer frames. Industrial carbon dioxide laser system was developed to weld the butted edges of the roll-formed shapes at speeds of 100 meters a minute or more.
