AUTO WELD CARRIAGE SySTEM The KAT® Auto Weld Carriage option enables a wide variety of automated welding and cutting overlay cycles that can be repeatedly performed The GSP control in this unit controls travel direction and speed and length of travel path and synchronizes them with precise weld start and weld stop settings This travel 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 Home Resistance Welding Supplies16 Oscillator Circuits and Applications fr = ⋅ 3 2 1 R R 4R C 1 16 3 Based on equation 16 3 by varying the value of resistor R 1 will change the frequency of the oscillator but not the peak to peak voltage which is governeditself If you want to get the most out of your welding practice your knowledge of welding must go beyond the arc You also need to understand how to control the arc and this requires knowledge of the welding circuit and the equipment that provides the electric current used in the arc Figure 1 is a diagram of the welding circuit TheOne of the important skills required is a good command of modern welding techniques The purpose of the Welding Handbook for maritime welders is to provide guidance in modern welding and related processes and to provide the welder with a source of practical information on the right solution to specific onboard welding problems weld oscillation Adjustable bracketry as well as vertical and horizontal Micro Fine Adjustable Rack Boxes allow the welding gun and the oscillator head to be easily mounted adjusted and accurately positioned in virtually any plane off the front or back of the “KAT”® carriage INTENDED / FORESEEN USAGEHigh precision state of the art controls on the KAT® carriage automatically direct the desired forward/reverse movement or dwell of the welding gun and its oscillation motion to produce the numerous weld patterns shown below The carriage control enables the carriage speed and direction to be pre set and shown on its LED display in IPM or cm/min

Instructions Fill out the worksheet as we cover the science of welding with a PowerPoint 1 _____ welding is a process used to join two pieces of similar metals together 2 A welder uses _____ energy to heat metal until it is molten 3 List 3 things that you use in your life that require welding a b c 4 The KAT® Weld Oscillation Automation Carriage is comprised of the Compact Oscillator head controls mounting brackets connecting cable 1 1/8" heavy duty micro fine rack boxes with rack arms for horizontal and vertical adjustments and standard MIG gun holder together with a KAT® carriage for rigid track or flex track as shown above the ideal position for downhand welding But sometimes a posi tioner performs another important function it provides the weld travel speed by securing a welding head in a fixed position and allowing the positioner to move the part This eliminates the op erator variable and is another major step toward better welds 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 Oscillation can be achieved by mechanically manipulating the welding head but oscillation of the arc alone is an attractive and cheaper alternative A simple electromagnet can be attached to the welding torch to produce a magnetic field in the welding direction which causes the arc to be deflected in the transverse direction penetration groove weld shall be the thickness of the thinner part joined No increase in the effective area for design calculations is permitted for weld reinforcement Groove weld sizes for welds in T Y and K connections in tubular members are shown in Table 3 6 2 4 Fillet Welds 2 4 1 Effective Throat 2 4 1 1 Calculation welding packets 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 When compiling this math reference packet care was taken to build onWelding Handbook Welding and Related Processes for Repair and Maintenance Onboard 14th edition 2nd revision Notice All welding is carried out on the welder’s own risk and account Welding should be executed by a qualified and experienced welder and adequate safety measures should always be adhered to •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 fit
