Researchers have developed a sophisticated IoT-based welding machine that is faster than conventional fusion welding methods or solid-state processes currently used with minimal power consumption. As the manufacturing industry advances in advanced technology, there is a need to reduce energy consumption and create an automatic welding process to avoid man-made mistakes and to produce products faster in a more environmentally friendly manner.
Drs. S. ArungalaiVendan, Professor, Electronics, and Communication, School of Engineering, Dayananda Sagar University, Bangalore has developed an integrated Internet of Things (IoT) machine entitled “Magnetically Impelled Arc Butt Welding Equipment” embedded with sound sensors, vibrations, light intensity. arc, temperature and humidity, and processors for issuing weld quality data predictors A low-cost IoT integrated machine supported by the Department of Science and Technology,
Drs. Vendan who received a Ph.D. at MIAB welding has tested the process at the Welding Research Institute, Bharat Heavy Electrical Limited, Tiruchirappalli, India for pressure component applications. Recognizing the great potential for adopting the process of applications from various industries to join the iron tubes, the researcher came up with the idea of making an inexpensive MIAB IoT integrated machine for assembling iron tubes.
Arc Butt Heating (MIAB) Magnetic field involves an arc strike between two tubes coaxially, followed by the axial interaction of the current arc section and the radial field of the magnetic field causing a force called the Lorentz force. This force acts on the arc and furthers the joint line at an average speed of 200m / s at the same temperature that the tube area reaches its highest temperature at solid (solidus temperature). The soft ends of the tube (the ends of the buttocks) are then forced into the fork to form a weld.
The upgraded material is designed for welding steel / carbon floor tubes of 3 mm outer diameter – 21.5mm, 22.5mm and 27 mm respectively with a thickness of 2-3 mm commonly used in automotive and building systems. Scientists are in the process of developing new two-dimensional parallel calculations– arc velocity and arc rotation noise, based on which limited predictions can be made about welding.
