Electric resistance seam welding is a welding method used to join two overlapping metal sheets in a seam weld. This welding process is widely used in various industries, including automotive, construction, and aerospace. In this article, we will shed some light on the working principle of electric resistance seam welding.
Electric resistance seam welding is a process that involves applying a high amount of electric current to two metal sheets that are placed in an overlapping position. The heat generated by this electric current softens the metal sheets, making them pliable enough to be joined seamlessly. This welding process is different from other welding methods as it requires no filler or flux material to join the metal sheets.
There are two main components in electric resistance seam welding: the welding machine and the electrode wheels. The welding machine supplies high electric current to the electrode wheels, which are placed on either side of the seam. When these electrode wheels come in contact with the metal sheets, they apply pressure and generate heat by passing a high electrical current through the metal sheets.
As a result of the pressure and heat generated by the electrode wheels, the metal sheets eventually soften and bond together. This bonding occurs due to the natural resistance of the metal sheets to the electric current generated by the welding machine. Hence, the name "electric resistance seam welding."
Electric resistance seam welding has several advantages over other welding methods. Firstly, it is highly efficient as it requires no filler or flux material that is used in other welding methods. Secondly, it results in strong, durable welds that can withstand high levels of stress and strain. Lastly, the welding seams produced by this method are leak-proof and can withstand corrosive environments.
Electric resistance seam welding is a widely used method in various industries due to its high efficiency, durability, and leak-proof sealing. The process involves applying high electric current to two overlapping metal sheets, generating heat, and fusing them together. The bonding occurs due to the metal's natural resistance to the electric current generated by the welding machine.
In conclusion, electric resistance seam welding has revolutionized the welding industry by providing a cheaper, more efficient, and reliable process for joining metal sheets. It is vital to note that proper safety precautions should be taken when handling electric currents to avoid accidents and injuries.
