Focusing on the engineering challenge of achieving stable, high-strength welding between rough metals surfaces and transparent materials, this work ...

Material fatigue is generally considered the most-common failure mode for welded parts and structures subject to dynamic loads and stresses. The two previous articles in this series delved into the ...

Plastics are long chains of specific polymers. The use of plastics has grown significantly owing to their high strength, high stiffness, high formability, and lightweight. Additionally, the most ...

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 Columbus, Ohio-based Path Robotics is building welding machines that can hop around a construction site or ...
