In order to automatically control the quality of the welding process, this paper concentrates on the problem of three dimensional surface reconstructions for the welding pool. As the relationships between size and shape of the welding pool are very complex and nonlinear, we utilize the fuzzy neural network to solve the proposed problem. In the fuzzy neural network, the input vector with 48 dime...

Gas tungsten arc welding (GTAW) or Tungsten inert gas welding (TIG) is one of the widely used techniques for joining ferrous and non-ferrous metal.Gas tungsten arc welding process,consist of non-consumable tungsten electrode which is used to provide the arc for welding. During the welding cycle a shield of inert gas expels the air from the welding area and prevents oxidation of the electrode, w...

Friction stir welding (FSW) is an emerging manufacturing technology for aerospace structures. It will see widespread use in the future as it offers ways of creating lighter structures at lower manufacturing cost than traditional methods (riveting, adhesive bonding). Since its invention in 1991, FSW has known fast improvements and many studies have demonstrated its capability for joining a wide ...

ABSTRACT: PC-ATOMIC is a PC interface for the ATOMIC LAN. PCATOMIC is implemented as a VL-Bus (VESA) short-form card for Intel i486 PCs, providing an interface for low-cost workstations to a 640 Mbps LAN. This document describes the PC-ATOMIC interface, its design, capabilities, and performance. The board design is public, and a small number of boards are available as government-furnished equip...

news. If you create conditions incompatible with life, the program lets you know your patient is dead, this is the MacMan equivalent of crashing your airplane in a flight simulator, and should this happen you merely start again, because there is no equivalent to reversing the program and resurrecting the dead. Some of the experiment options include: cutting the buffer nerves, resetting barorece...
