Ultrasonic welding systems help manufacturers achieve higher efficiency while meeting demanding industry specifications for ...

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 ...

Besides ambient airflow and filtration options, hoods, and weld helmet respirators, shops have four basic alternatives for ...

Equipment And Technologies For Ultrasonic Welding Of Polymeric Materials. The Institute of Technical Acoustics offers ...

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 ...

Laser–arc hybrid welding (LAHW) combines the deep penetration and speed of lasers with the filler and gap-bridging capabilities of arc welding, producing stronger, faster, and cleaner welds. This ...

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 ...

Unlike composites made with a thermoset matrix, thermoplastic composites (TPCs) require neither complex chemical reactions nor lengthy curing processes. Thermoplastic prepregs require no refrigeration ...

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 ...
