Reduction of Biomechanical and Welding Fume Exposures in Stud Welding.
The welding of shear stud connectors to structural steel in construction requires a prolonged stooped posture that exposes ironworkers to biomechanical and welding fume hazards. In this study, biomechanical and welding fume exposures during stud welding using conventional methods were compared to exposures associated with use of a prototype system that allowed participants to weld from an uprig...

MAY 2003 -S 116 ABSTRACT. Mechanical characteristics of resistance spot welding machines, such as stiffness, friction, and moving mass, have complex influences on the resistance welding process and weld quality. In this paper, these influences are systematically investigated through experiments. The mechanisms of the influences are explored by analyzing process signatures, such as welding force...

APRIL 2004 -S 140 ABSTRACT. This article analyzes the mechanics of the metal ultrasonic welding process as a basis for a new solid free-form fabrication technology. Three-dimensional prototypes are constructed by ultrasonic welding of overlaid metal foil laminations, followed by contour cutting of the 2-D layers. This was implemented in the laboratory by a computer-automated ultrasonic welding ...

-s 1 WELDING JOURNAL ABSTRACT. Brazement design is a critically important characteristic of a brazed joint structure. The design is responsible for reliability and proper service behavior of brazed products. According to the state of the art, a good design provides not only required properties of the brazed structure, but also a very high technological suitability. The latter is necessary in or...
