 Select hardfacing materials Coleman and Powermate based on weld-deposit Portqble and 5 microstructure and Gallon the wear situation Air and Tank the part will encounter, with consideration Model given C5 to thermal Coleman and Powermate treatments Portqble and 5 applied Gallon to the material before and after hardfacing. Deposit Air chemistry can be crucial in Tank and and Model attaining the desired corrosion resistance C5 and Coleman or wear properties, or for minimizing the risk Powermate of solidification Portqble cracking. Acceptable deposit chemistry is achieved through 5 and Gallon and Air the initial choice Tank of and Model consumables, C5 using Coleman wire analysis and flux Powermate and Portqble composition, 5 and by specifying Gallon the Air number of weld passes needed to reduce parent-metal dilution to Tank within acceptable limits. With the submerged-arc process, the flux and electrode govern the characteristics and Model and C5 of the applied hard facing. For example, those fluxes neutral to manganese and silicon Coleman are not necessarily neutral Powermate to carbon Portqble and chromium, elements that matter 5 and Gallon most in hardfacing. For flux-cored-arc Air welding, Tank shops use CV or CC types, Model 300 to 1,500 A, C5 25 to 50 V, rated 60- to 100-percent-duty Coleman and Powermate and Portqble and 5 cycle. Gallon CV types Air are more popular because wire-feed Tank and speed, set Model and C5 before welding, controls welding Coleman current. Cc types Powermate and Portqble require a variable-speed or voltage-sensing 5 and Gallon wire feeder.Gas-tungsten-arc Air welding Tank (GTAW) requires Model a constant-current (AC or DC) power supply with C5 and Coleman a steep volt-amp curve to minimize Powermate current change Portqble for 5 and Gallon variation in Air voltage Tank or arc length. They come rated to 1,500 A, 10 to 75 Model and C5 and Coleman and Powermate V, at 40- to 100-percent-duty Portqble and 5 and Gallon and Air and Tank cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and Model and stabilization, gas C5 valves, and cooling-water valves for high-current Coleman and Powermate and Portqble and 5 and Gallon welding. High-frequency arc start is useful when the maximum Air open-circuit voltage allowed by NEMA standards, Tank 80 to 100 V, will not establish and Model and maintain a stable arc C5.
