TITLE: Precise Process Control and Automation for HF Welding

ABSTRACT: High frequency (HF) Welding is a type of electric resistance welding in which metal strip edges are heated using induced current before being forged together continuously to create a high-quality longitudinal seam weld.  HF welding relies on the control of parameters such as welder power (kW), frequency (kHz), weld area geometry, impeder function, raw material geometry and chemistry. In today’s competitive world delivery time is paramount, making yield loss and scrap reduction important dimensions of tube and pipe mill productivity. Modern transistorized HF Welders are very reliable, but many do not offer sophisticated control and automation features. It is vital to closely monitor process parameters and track their effect on weld quality.  Once a process has been validated through product performance testing, it is essential to have a control and automation system in place that enables reproducible process results. The latest process control tools, combined with a high frequency power supply designed to precisely control HF Weld Heat Input, can be used by tube and pipe manufacturers to deliver the highest quality products to the customer with high statistical reliability.  This presentation focuses on the benefits to operators who now can use the latest tools to optimize process parameters, collect and analyze process data, and implement the technology-driven automated methods for the HF Welding of tube and pipe.

TITLE: Data Collection and Implementation of IIoT enabled equipment for HF Welding

ABSTRACT: There has been a notable shift towards enhanced connectivity of equipment and greater emphasis on data collection and analysis, including the tube and pipe industry. HF welding requires precise control of various process parameters such as power, frequency, weld area geometry, impeder, and raw material. It is crucial to closely monitor these parameters and know their effects on the quality of the weld. Once the process has been validated through product performance testing, it is essential to have a good data collection system, paired with process control and automation in place that can deliver reproducible results. This presentation aims to help operators maximize the efficiency of their tube and pipe welding process by utilizing the latest tools. This includes precise process control, collecting and analyzing process data, and implementing technology-driven automated methods. This presentation also covers the infrastructure changes and data management strategies for implementation of IIoT-enabled HF welders.

TITLE: Two-Stage Post-Weld Heat Treatment (PWHT) of API HF Welds using Induction Technology

ABSTRACT: As steel chemistries have become more complex in pursuit of higher performing materials, Post Weld Heat Treatment (PWHT) of HF Welds has become more common.  Most API® tubular products intended for use in oil and gas gathering and transmission applications are subjected to some PWHT process.  With advances in steel material technology over the past 10 years, there has been an increased demand for a Normalizing, Quenching, and Tempering (NQT) process for HF Welded tube and pipe to improve their Weld Heat Affected Zone (HAZ) mechanical properties.  Attendees will learn the fundamentals of the quench and temper heat treatment process and will understand the proper design aspects of an HF Weld Seam induction heat treating line.  The discussion will focus on proper heating techniques, precision quenching with focused Weld HAZ performance enhancements, and a basic understanding of induction tempering.
