Wires offer easy welding

February 25, 2008 – 12:35 pm
The slag from Shield-Bright stainless cored wires is self-lifting or easily detached, leaving behind clean, flat weld surface with a good penetration and very smooth wetting onto the plate edges ESAB's latest Shield-Bright stainless cored wires are rutile types with an excellent weldability on conventional nonpulsing power sources under Ar/CO2 mixed gas and CO2 shielding gas. Always operating in the smooth spray arc mode, they are welder-friendly wires with a very low spatter level. The slag is self-lifting or easily detached, leaving behind clean, flat weld surface with a good penetration and very smooth wetting onto the plate edges. The all-positional Shield-Bright wires have a fast freezing slag. This allows deposition rates in positional welding that cannot be equalled by stick electrodes or solid wires. Typical positional welding defects, such as lack of fusion and slag inclusions are avoided. The Shield-Bright X-tra range is suitable for downhand and horizontal vertical fillet welding, having a slow freezing ...

Software defined silicon nears reality

February 25, 2008 – 12:34 pm
Innovative multiprocessor approach to configurable semiconductor devices brings a new level of flexibility and low cost to a broad range of consumer applications XMOS Semiconductor has created working silicon and beta design tools for its Software Defined Silicon (SDS), a new class of programmable semiconductor. Test chips were produced by TSMC on its 90nm G process. XMOS' innovative multiprocessor approach to configurable semiconductor devices brings a new level of flexibility and low cost to a broad range of consumer applications. Central to the XMOS technology is a compact event-driven multithreaded processor called XCore. With up to 500MIPs to share across up to eight threads, the XCore engine readily implements a range of complex hardware functions. Access to its computational and control capabilities is through a familiar embedded software design flow. By using C-based behavioural languages, designers can quickly map white-board functional specifications into silicon. David May, CTO and founder of XMOS says: 'We estimate that the ...

Silicon-on-sapphire pressure transducer technology

February 25, 2008 – 12:33 pm
Resistive pressure measurement has taken the lead as the most popular sensing technique in the manufacture of pressure sensors: this article explains the development of silicon-on-sapphire technology The applied pressure causes the deformation of a diaphragm. This deformation is translated into a proportional electrical signal by means of a strain gauge attached to the diaphragm. Initially, the strain gauge was cemented to the diaphragm. This three component system (strain gauge-cement-diaphragm) suffers from creep and hysteresis, a phenomenon usually caused by the cement and poor signal to noise ratio. The demand in industry was for more stable and repeatable sensors: this opened the door for the introduction of solid-state sensing. Solid state silicon piezo-resistive pressure sensors offered some improvement over the bonded type of sensor with regard to sensitivity and repeatability, although it had limited ability to operate at varying temperatures without expensive temperature compensation, and could be only used on dry air. Expensive oil ...
