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.
