Monitoring the Weld V Temperature on a HF Tube Mill

On this version of “Tales from the sphere,” we current an enchanting case research of considered one of our esteemed prospects.

Delve into API pipe manufacturing, exploring weld intricacies and temperature dynamics in HF tube mills. Analyze temperature disparities earlier than welding, uncovering insights into heating and thickness consistency. Make the most of cutting-edge know-how at welding junctures to detect abnormalities and set up benchmarks for excellence. With a specialised digital camera offering real-time insights, improve your understanding and confidence in welding.

Embark on this discipline story to witness how this answer reshapes our outlook on welding.

An API pipe producer was all in favour of measuring the geometry of the weld V on the level of welding on an HF tube mill, but in addition all in favour of measuring temperature of quite a lot of key options of the method, specifically:

  • Temperature distinction between both strip edge previous to the weld level. The pipe producer felt this was vital to point if the each side of the strip have been evenly heated previous to being squeezed collectively.
    The induction coil place, in addition to the impeder situation, or its arrange, could affect power concentrations on one strip edge in a different way from the opposite.
    Alternatively, temperature variations might point out thickness variations between both aspect of the strip.
  • Measuring the temperature response of the weld course of at a few key factors: proper on the weld apex and a hard and fast spot on the finished weld bead.
    Apex is discovered by searching for the most well liked level on the weld bead utilizing the native temperature most.
    An extra fastened measurement spot at or after the weld roll centerline provides us the ultimate bead temperature. Utilizing each factors collectively can probably point out warmth penetration charges.

By means of using sw instruments, the operator is ready to set course of limits and set working vary limits that might set up finest practices. The aim can be to present the operator measurable course of suggestions with alarms in order that the operator has a early indicator to course of anomalies.

Buyer Success:

A Xiris SWIR thermal digital camera that was calibrated to 1800°C was positioned on the HF weld surroundings to have a look at the weld “V” instantly after the induction coil offering actual time temperature knowledge of the weld course of. As soon as temperature working parameters have been established, the operator was capable of set alarms that will notify manufacturing employees if course of anomalies happen.

What have been the outcomes or advantages achieved?

Actual time temperature measurement that allows higher understanding of the weld course of.

Temperature knowledge of the method impressed extra confidence within the welding course of by the fabricator
