Technical details about the preheating process
Preheating welds is essential to prevent defects and ensure the structural integrity of welded joints. At INTEC-HEAT, we use precise temperature control systems and state-of-the-art programmers that maintain a uniform and controlled temperature throughout the entire welded piece. These systems are designed to adjust to different geometries and thicknesses, ensuring adaptability to the specific needs of each industry.
High-precision temperature sensors allow us to maintain established tolerance ranges, automatically adjusting the process to compensate for any deviations. In addition, our equipment allows for real-time adjustments, optimizing the efficiency and quality of preheating in critical applications, from pipes to thick components in complex industrial structures.
Detailed description of preheating methods
At INTEC-HEAT, we offer two main preheating methods, each with specific advantages depending on the customer’s needs:
1. STATIC
- Electric, using resistors. The required temperatures during the process are achieved by directly applying electrical resistors at the appropriate distance from the weld. The flexibility of these elements makes them ideal for adapting to any geometry.
- By induction. High-frequency cables wrapped around the element to be welded generate molecular excitation and a consequent rise in temperature. We use the most advanced equipment and water-cooled cables for greater safety during the process.
2. WELDED RINGS IN MOTION
- Electric, using resistors. The use of radiation through specific resistors and their placement using suitable supports allows preheating to be carried out with the ferrules rotating without any contact occurring. Temperature control is carried out using infrared sensors.
- By induction. The rolling inductor allows preheating of moving parts. By sensing the movement of the part, we can perform automatic disconnections that prevent overheating in the event of unexpected welding stoppages.
Benefits of working with INTEC-HEAT
INTEC-HEAT has over 35 years of experience in heat treatment and an international presence, with operational teams around the world. Working with INTEC-HEAT means having a team of experts who offer tailored and customized solutions according to the needs of each project. In addition, our focus on quality and safety makes us a leading supplier for industries that require precision and strict compliance with international heat treatment standards.
Advanced technology and process safety
Safety and control are fundamental pillars of INTEC-HEAT’s processes. Our equipment is equipped with infrared sensors and remote control technologies that allow temperatures to be adjusted and automatic shutdowns to be performed in the event of unexpected stoppages. This remote control technology allows our customers to observe the process in real time and maintain control of each phase. Our goal is to offer comprehensive technical support that guarantees continuous operation and rapid resolution of any incidents. This capability is especially valuable in sectors where safety is critical, such as offshore facilities and refineries.
Sustainability and energy efficiency
At INTEC-HEAT, we are committed to sustainability. Our preheating methods are designed to minimize energy consumption through the use of high-efficiency equipment and process optimization techniques. For example, the use of induction in preheating allows for more direct and rapid heat transfer, significantly reducing the time and energy required compared to conventional methods.
Furthermore, by preventing defects and optimizing the life cycle of treated parts, we contribute to reducing waste and maintenance requirements in high-demand applications. This translates into benefits not only for our customers, but also for the environment, by reducing emissions and energy consumption.
