Princípio de funcionamento

O Tubo de aleta para soldadura de alta frequência is manufactured by feeding the fin strip into a high-frequency welder and continuously winding it onto the base tube. The welding machine uses electromagnetic induction to generate heat, which results in strong metallurgical bonding between the fin and the tube without any filler material.

This process ensures high heat transfer performance and structural strength.
