Jugular venous monitoring (necessary during chemically induced coma only). The problem with increased ICP is that the fluid under pressure tends to deform the brain itself and pushes tissue in such a way as to cause injury to the brain itself. A MRI or CT taken at the emergency room or during follow-up care, can often show the shifting of the tissue because of the pressure.
Electron beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact.
Inductance, in particular, plays an important part in obtaining proper puddle fluidity. The shielding gas recommended for short-circuiting welding of stainless-steel contains 90% helium, 7.5% argon, and 2.5% carbon dioxide.The gas gives the most desirable bead contour while keeping the CO2 level low enough so that it does not influence the corrosion resistance of the metal. current of approximately 300-350 amperes is required for a 1/16-in. electrode, depending on the shielding gas and type of stainless wire being used. The degree of spatter is dependent upon the composition and flow rate of the shielding gas, wire-feed speed, and the characteristics of the welding power supply.
