High Frequency Electric Resistance Welding Carbon Stm A53 Grade B Pipe Steel Pipe

Technology is introduced

High frequency welding is the effect of skin effect and the adjacent high frequency current generated by the use of the butt plate and other metal materials up new welding process. Emergence of high frequency welding technology and mature, directly contributed to the development of Longitudinal huge industry, it is a key step Longitudinal (ERW) production. The quality of high-frequency welding, pipe a direct impact on the overall strength of the product, quality levels and production rate.

Many factors affect the quality of the high-frequency welding, and the interaction of these factors in the same system, a factor that has changed, other factors also as it is changed. Therefore, when high-frequency adjustment, frequency adjustment of the local light is noted that the current is insufficient or the amount of compression, etc., which must be adjusted according to the specific conditions of the molding system, from all aspects related to high-frequency welding adjustments. After the high-frequency welding necessarily exclude air, is: In real tool joints, expel excess air, full of welds purpose.
