The Barkhausen criterion for sustained oscillation is Aβ = 1 where A is the gain of the amplifier and β is the feedback factor gain The unity gain means signal is in phase If the signal is out of phase and gain will be 1 RC Phase shift Oscillator has a CE amplifierApplying Barkhausen principle of oscillator design this shall mean that overall loop gain A = j j ω ω ω RC 3 1RC R C − 2 2 2 AV = 1 From real part and imaginary part of the complex number solution the resonant frequency fr of the oscillator shall be fr = 2 RC 1 π 16 8 The voltage gain A V of the amplifier should be 3 This shall MFMcGraw PHY Chap 15Ha Oscillations Revised 10/13/ 26 The period of oscillation of an object in an ideal mass spring system is sec and the amplitude is 5 0 cm What is the speed at the equilibrium point At equilibrium x = 0 2 2 2 2 1 2 1 2 1 E = K U = mv kx = mv Since E = constant at equilibrium x = 0 the KE must be a maximum Mar 26 design practices and techniques to ensure robust operation A poorly designed oscillator circuit will have reduced frequency accuracy and may not function correctly over temperature and voltage ranges Key features for robust operation are 1 Dry and moisture free circuit boards 2 Clean circuit boards that are free of contaminants 3 The worksheets have been collected edited and rearranged in an order that we hope will be helpful to all welding students whether you are taking just a few classes for welding skills upgrade or you are a degree or certificate seeking student Dec 31 Oscillation is not the same as " width of the weld bead" Oscillation is the amount of electrode movement Say for example the weld puddle width is 1/4 inch without oscillation and a 1/8 inch diameter electrode is used that is oscillated 2x the diameter 1/4 inch The final weld bead width would be about 1/2 inch from toe to toe ˇˆ˙ˇ˝ ˛˚ ˘ ˇ ˆ ˙ ˘ ˇˇˆ Title A21 Author Default Created Date 7/25/ 8 48 45 AMoscillation circuit design considerations ECS INC INTERNATIONAL S RIDGEVIEW OLATHE KS • • • FAX •

•Oscillation welding uses a single mode high power laser with a scanner to rapidly move the laser beam in the weld pool •The weld depth and width can be controlled independently •Adjust scanner parameters to control weld shape •For best results oscillation frequency should be high •Oscillation welding is more tolerant to gaps and fitMay 30 Oscillation is the side to side manipulation of a weld in progress It is measured in amplitude how far frequency how often and dwell time for how long There are a number of ways and reasons a weld process would be oscillated If you spend any time around robotic gas metal arc welding GMAW you ll notice that the welding torch Oscillation of the weld pool manipulation of the electrode to create a weaving pattern of the weld pool In your case it means that the width of the weld pass distance between the toes of the weld be 2 times the diameter of the electrode being used to produce the weld SSBN Run Silent Run Deep!!! Thanks!!!KAT® Weld Oscillation Automation Carriage This advanced weld oscillation system is designed to increase production and improve the quality of the weld produced in automatic mechanized welding operations by minimizing weld defects such as poor penetration incomplete fusion overlap and undercut The GK Series automation carriages come A real craftsman will rock that GTAW cup along the joint and make a beautiful finish weld with a consistent fact completely around the pipe joint The end result can be a real work of art or a real cobbled mess for that matter Another type of oscillation is manipulating the molten weld pool with a magnetic force Tuned Oscillators use a parallel LC resonant circuit LC tank to provide the oscillations There are two common types • Colpitts – The resonant circuit is an inductor and two capacitors •Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor R is the largest single factor in oscillator design and dominates the design of every oscillator circuit Figure 2 4 shows the maximum drive power that can be put into a crystal without excessive heating and frequency shift in the crystal Fig ure 2 5 shows the maximum permissible drive voltage across the crystal at exact series resonance WELDING This diagram shows a typical welding Gantry/Bridge unit design The long tracks are located underneath the table providing protection This also allows the work piece to be easily loaded at any point on the table as it is clear and easily accessible The bridge unit can be equipped to automatically position and clamp the parts to be welded 1 1 Metals & Fabrication Basic MMAW Chapter 1 – Arc welding safety Introduction To achieve safe working conditions in the metal fabrication and welding industry all personnel should be able to recognise the hazards which apply to their particular
