Spot welding machine is a type of welding equipment that is commonly used in manufacturing and fabrication processes. It works by applying pressure and heat to two pieces of metal, creating a bond between them. The spot welder consists of two electrodes that deliver an electric current to the metal pieces, creating a concentrated heat at the point of contact. This technique is commonly used in the automotive industry for joining sheet metal components, as well as in the construction of appliances and electronic devices. One advantage of spot welding is its speed and efficiency, making it a popular choice for high-volume production lines. Additionally, spot welding creates a neat and clean bond that is typically stronger than other types of welding methods.
