The production of steel tubing uses sheet stock that is formed into a tubular shape by passing through a series of roller stands and an induction welder. The welder heats the seam to a high enough temperature to ensure a strong weld, as the metal is being forced together. Induction welding is a common method of steel tube production, where temperature control is essential to maintain quality.
Four different welding processes are typically used for making tubes: High Frequency (HF) Welding, Electric Resistance Welding (ERW), Gas Tungsten Arc Welding (GTAW), and Laser Welding. The temperature measurement of the welding is critical to achieve the highest quality at the highest speed and ensure the lowest possible energy costs. The temperature measurement will usually be fed back and looped into a PLC system, where the power or gas consumption can be adjusted.
- Monitor temperature throughout the process with latest communication protocols to allow fast feedback and adjustment
- Track temperature and analyze trends (predictive maintenance and historical data)
- Support demands of production line speed, achieve lowest energy cost and maintain highest product quality
