High-Frequency Resistance Welding
HF resistance pressure welding uses high-frequency current for fast, efficient welding of pipes and profiles via edge contact. It boosts productivity and improves the mechanical properties of the joints.
Physical-Chemical Mechanism
HF resistance pressure welding uses high-frequency current to join metal parts through edge contact. The current generates heat at the weld seam and fuses the materials together.
Metallurgical Relevance & Welding Risks
This process improves the mechanical properties of the weld through even heat distribution. However, uneven current flow can cause stresses, leading to cracks or wear issues in the material.
Shop Practice & Action Guidelines
Use a high-frequency generator with a suitable edge contact. Set the current and frequency based on the material and part size. Ensure even pressure distribution and control cooling to avoid cracks.
