Soft metal weld makes for stronger infrastructure
Scientists have found applying a soft metal layer before welding hard metals can act as a sufficient buffer to address fatigue behaviour in welded metal.
Improved material for 'laser welding' of tissue in intestinal surgery
A new "solder" for laser welding of tissue during surgical operations has the potential to produce stronger seals and expand use of this alternative to conventional sutures and stapling in intestinal surgery, ...
Laser welding as an engine of innovation
Lasers have long been able to do what traditional welding guns can. Nevertheless, many manufacturers did not dare employ the delicate technology in the raw environment of their assembly floors. At LASER 2013 (Hall C2, Booth ...
Space sailing soon: A one-kilometer-long electric sail tether produced
The electric sail (ESAIL), invented by Dr. Pekka Janhunen at the Finnish Kumpula Space Centre in 2006, produces propulsion power for a spacecraft by utilizing the solar wind. The sail features electrically ...
Stirred, not shaken: Bond for future ships, iMacs has ONR roots
A state-of-the-art welding process refined for use in naval shipbuilding by the Office of Naval Research (ONR) has crossed over to the world of computing.
Simulating phase transformations during the welding of ferritic steels
A new model developed by research scientists at ANSTO to predict the structural changes in stainless steel during welding could help improve safety and integrity in critical engineering components.
Welding of steel and aluminum a first on frames of mass-produced vehicles
Honda Motor today announced that it has newly developed a technology for the continuous welding of the dissimilar metals of steel and aluminum and applied it for the first time in the world to the subframe ...
Helium shortage is on, and prices are up, up and away
A helium shortage is nothing to take lightly. Nothing funny, either, in how some are talking about their livelihoods, whether it's keeping those party balloons flying or those MRI magnets cooled.
NASA researchers looking to take additive manufacturing into space
Friction stir welding unites reliability, affordability
(Phys.org) -- NASA's next heavy-lift launch vehicle, the Space Launch System, is moving further in development faster thanks to proven advanced technologies like friction stir welding.
Harnessing plasmonics, engineers weld nanowires with light
At the nano level, researchers at Stanford have discovered a new way to weld together meshes of tiny wires. Their work could lead to exciting new electronics and solar applications. To succeed, they called ...
Deep space capsule comes alive with first weld
(PhysOrg.com) -- Construction began this week on the first new NASA spacecraft built to take humans to orbit since space shuttle Endeavour left the factory in 1991, and marked a significant milestone in carrying ...
Perfect welds for car bodies
Surface welding instead of penetration welding, allows a laser to produce a weld that is only visible on one side. But how do you control the laser power to prevent it burning a hole through the sheets of ...
Cranfield university reaches record breaking depths in deep sea welding
(PhysOrg.com) -- Research at Cranfield University has led to new world record depths in deep sea subsea welding. The results will significantly impact the offshore pipeline industry across the oil and gas, and renewable energy ...
