Early power supplies for contact and induction welding for tube production, which were introduced in the 1950s, operated at 300 to 400 kHz. Modern power supplied, introduced in the 1990s, are variable from 200 to 400 kHz. While using any frequency in this range can produce acceptable welds for most applications, finite element analysis can be helpful for finding the optimal frequency for a particular gauge and material.
