The capabilities of the welding process with high frequency currents (HF)
High-frequency electric welding is intended for the production of structural sections with unlimited profiles. The process is characterized by high connection speeds, preservation of all structural characteristics of materials. At the same time, there is no increase in the weight of the finished welded structure, since there is no overlap of the new material on the weld zone. This, contributes to preserving the original appearance of the junction zone, and requires additional operations for its grinding.
The essence of HDTV
When welding the HDTV, the amount of heat introduced into the zone of connection is minimal, it is important to ensure the formation of a zone of thermal influence with a changed microstructure. Electromagnetic energy is used in combination with high pressure to connect two materials. The material is connected by heat and pressure instead of melted together with the filler. Monitoring key parameters of the welding process, such as frequency and amplitude, allows you to control the time and temperature, which leads to small dimensions of the heat affected zone and improved properties of the metal in the weld zone.
The strength of the weld zone in welded structures is close to the strength of the initial material. This technology is suitable for welding low- and high-strength materials, dissimilar metals and various sizes and shapes. The welding process is characterized by high productivity, and does not depend on the configuration of the products in the welding zone.

Setting parameters for the welding process of HDTV
The welded beam has a certain degree of adjustment. In addition to asymmetric and configurable geometries, it can be performed even when cutting pieces. This helps to ease installation, and reduce the total welding time. In addition to individual calibration, the process helps to reduce material costs due to the thinner cross-sectional area. These changes have little effect on strength, but have a significant effect on reducing the weight of the welded structure, which reduces metal losses in waste.
Welding technology
Weld zones are formed by means of slotted coils. Three coils are used for sections of H- and I-profiles. The coil is fed into the center of the decoiler on a reel machine and loaded onto the uncoiler using a mandrel controlled from the hydraulic drive. The coil reel aligns the leading edge of the coil, and the welding and end welder simultaneously cuts the front and back edges of each coil and welds them together for continuous operation. Cutting is done with two scissors, and welding is performed by semi-automatic gas welding or gas welding with a tungsten arc. At the point where welding takes place, the correct compression pressure is provided by a set of compression rolls.
Frequency welding machines transmit energy through copper contacts. The high frequency current heats the edges of the strip before they pass between the welding rollers. The upper and lower flanges are then welded, and any impurities in the molten metal are forced out during the welding process in the solid state. This results in a clean welding zone, both on the upper and lower flanges.
Popular welding applications for HDTV are conveyor assembly, transportation, residential and industrial construction.
