Narrow gap welding is a joining process that is most often used to weld thick sections of material economically. It requires preparation of the joint with steep angles designed to require less weld metal and less welding time to fill the joint which is usually no more than about 25 mm (1”) in width. Tungsten Inert Gas Welding (TIG or GTAW) is often used as the welding method of choice for many narrow gap welding applications such as pipe welding, pressure vessel construction and other critical fabrications and is often integrated into weld automation equipment such as in orbital welding or li ..read more

The world of tube manufacturing is undergoing a deep transformation, and at its core is the pursuit of precision and efficiency. Innovative inspection systems are playing a pivotal role in this revolution, enabling manufacturers to embrace the future of welding technology. In this blog, we'll explore the evolution of High-Frequency Induction (HF) welding and how technology is shaping its future ..read more

Choosing a thermal camera for your specific process in today's market can be quite a challenge due to the wide selection available. In this blog, we will discuss the various aspects of thermal cameras and their performance in hot metal processing applications, such as welding and wire-based metal AM. Specifically, we will compare near-infrared (NIR) and short-wave infrared (SWIR) thermal cameras when monitoring or measuring the temperature of welding processes. Both NIR and SWIR cameras have gained popularity in various industrial applications, successfully competing with traditional Mid-Wave ..read more

Xiris Weld Cameras are often used to enable operators to view the welding process remotely and monitor welding processes, improving operator safety and efficiency.  With the need for higher levels of efficiency and automation, adding weld cameras that can be used to measure and track welding features is becoming ever more important.   The XVC-750 weld camera combines 140+dB of High Dynamic Range (HDR) capability with Near Infrared (NIR) sensitivity to provide high contrast images in and around the melt pool. NIR sensitivity enhances the image contrast in the image by adding a c ..read more

High-speed mode of XIR-1800 In previous blogs, we talked in detail about the thermal measuring capabilities of the XIR-1800 thermal camera. In this blog we would like to discuss another feature that is often beneficial for research: higher speed imaging. In welding or additive manufacturing (AM) research, it is often necessary to look deeper into the welding process to get an insight that cannot be provided by a naked eye. Droplet transfer and motion of the weld pool are more rapid than what can be detected by a human eye. Standard weld cameras also might not be able to provide a high enough ..read more

Capturing high-quality images of aluminum can be quite challenging due to various factors. However, in this video, we get a special glimpse into the Fronius CMT welding process, showcasing the intricate details of this technique captured using a thermal camera. Imaging aluminum welding is particularly tough because the metal is so highly reflective, has a significantly lower melting point than other metals, typically around 660°C, and dissipates heat very quickly once welded. As a result, it can be very tough to get good images of aluminum welding processes. To accomplish this feat, a Xiris X ..read more

In certain welding applications, the surfaces to be welded together are required to be preheated before welding commences ..read more

In the world of metal tube and pipe manufacturing, precision and efficiency reign supreme. High-Frequency Induction (HF) welding offers speed and versatility but comes with intricate challenges. Let's explore how advanced inspection systems are transforming this industry, with a special focus on tackling the question, "How to measure V-angle in HF welding?" The HF Welding Conundrum HF welding is well-known for its ability to handle various tube diameters and thicknesses, making it a preferred choice for manufacturers. However, it demands meticulous control over parameters like mill geometry ..read more
