Boosting efficiency in solid state welders

  • Special PhenomenaElectrical and Mechanical RelationshipsIdeal Conditions in The VForming ToolingWeld RollsConclusionThe welding process depends on two phenomena associated with high-frequency currentskin effect and proximity effect. Skin effect is the tendency of the high-frequency current to concentrate at the surface of a conductor. In Figure 2, the high-frequency current flows in isolated conductors of various shapes. Almost the entire current flows in a shallow skin near the surface of the tube. Proximity effect is the tendency of the high-frequency current in a pair of go/return conductors to concentrate in the portiTex-Fin, Inc. - Posts FacebookOur High Frequency Helical Serrated Finned Pipes are made from metal strip that has been serrated or cut and then helically wound around the specified pipe.
