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 ...

Welding refers to a wide variety of processes in which metals are joined by fusion. The metal at the interface of two or more parts is melted or fused by application of intense, localised heat. A ...

The fabrication of fuel cells relies on a rapid laser welding process. However, challenges arise with the occurrence of humping when the welding speed surpasses a critical threshold, which poses ...

Welding Handbook, Volume 3, reflects the dramatic changes brought into welding processes over the past decade due to the emergence of new welding techniques and advanced materials. Included are ...

Inconel 718 is a precipitation-hardenable nickel–chromium–iron superalloy prized for its exceptional strength, corrosion resistance and stability at temperatures approaching 700 °C. It finds ...

Thermal distortion can push precision welds out of tolerance despite careful process control. Learn how preheating, clamping, ...

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 ...

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, ...

Thermoplastic composite (TPC) welding has been a key topic for CW since the March 2006 feature, “Thermoplastic composites gain leading edge on the A380”. That article described GKN Fokker’s (Hoogeveen ...

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 ...
