Why HF Erw? Welded Beam Customization HF Erw Enables Lean Manufacturing Applications Weld Quality.Solid-state, high-frequency welding for ESS in general requires minimal heat input, produces a narrow heat-affected zone (HAZ), and results in improved weld properties. The solid-state weld process uses less heat input because high-frequency (150-400 kHz) electromagnetic energy is used in conjunction with high pressure to join two materials. The material isjoined under heat and pressure instead of melted together with a filler material. Controlling key welding proce See more on thefabricator High Frequency Resistance Welding - Tulsa Fin TubeUneven spume is an indication of uneven welding conditions and usually of poor weld quality. It can be caused either by mechanical irregularities in the mill, such as deforming wheels, fin tilt roller, tips or excessive weld power.
