Developed in the 1940s, AA7075 is an aluminum alloy that's almost as strong as steel, yet it weighs just one third as much. Unfortunately its use has been limited, due to the fact that pieces of it ...

Everyone’s talking about Industry 4.0 nowadays. It’s a hot topic for society, politics and the economy. But what about digitisation in metal-working companies? What does it mean for joining technology ...

The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...

Cutting and welding tasks are performed either on a routine or infrequent basis in all industrial and commercial environments by maintenance personnel or contractors during the fabrication process, ...

In the tungsten inert gas (TIG) welding process, an electric arc is struck between a refractory electrode made of tungsten and the work piece, while a shroud of inert gas, usually argon, shields the ...

Welding is often a hot and noisy process. It generally involves some fancy chemistry and proper knowledge to achieve good results. Whether you’re talking about arc, TIG, or MIG, these statements all ...

Research center Laser Zentrum Hannover (LZH) is researching ways to make welding thick plates in shipbuilding more reliable. The scientists are developing a multi-laser beam welding process with ...

Arc welding using the Metal filler wire as consumable electrode and an Inert Gas to protect the molten pool against oxidation. Figure 1. Schematic of the MIG welding process. In the metal inert gas ...

Components for the aerospace or transportation industry are typical applications for fibre-reinforced thermoplastic polymer composites. These components often require the production of large, complex ...

Thermoplastic composites welding has the potential to significantly improve the sustainability of commercial aircraft production. Tier 1 airframer Collins Aerospace (Charlotte, N.C., U.S.) claims on ...
