  • Metallurgical Interpretation of Temperature DataFactors Used to Determine Weld QualityConsiderations in Finite Element ModelingModeling ResultsMaking The Best ChoiceHigh-frequency welding is a very forgiving process when used on low-carbon steel; good welds can be achieved over a range of frequencies. However, better weld quality can be achieved by carefully researching the results achieved with different weld frequencies. In general, welding thinner-walled tubes at higher frequencies and thicker-walled tubes at lower frequencies improves tube qualities.Exceptions might be coated materials or special alloys that require experimentation to determiWelded steel pipe:Welded Tube and Pipe Manufacturing The longitudinal edges are continously joined by high frequency resistance/induction welding.

    PRINCIPLES OF HIGH FREQUENCY INDUCTION TUBE

    limitation of about 2-3 degrees for carbon steel tubing and 5-8 degrees for stainless & non ferrous materials. Work coils Current flowing through the work coil establishes a magnetic field that causes energy to be induced into the tube. Coil current increases with weld power & decreases with frequency, but at any frequency used
