Infrared welding offers several advantages, including fast heating using radiation energy, avoiding the formation of loose particles that occurs with vibration welding, clearing up uneven places on the weld and reducing the size of the welding bead. Infrared also uses less energy, as it is only heating during the heating process.
Hot-gas welding is a horizontal, two-stage welding process that channels the hot emissions from the fuel specifically onto the weld seam.
Bielmomatik also introduced a hybrid welding machine, the K 3217, that combines vibration and infrared welding. The company also makes laser-welding machines.
The company's U.S. unit, Bielomatik Inc., is in New Hudson, Mich.
