Spot welding is a resistance welding technique used to join overlapping metal sheets by applying pressure and passing an electric current through the contact point. It produces localized heat that melts the material at the weld spot, forming a strong bond upon cooling. Commonly used in automotive, appliance, and aerospace industries, spot welding is known for its speed, efficiency, and suitability for thin sheet metals. Spot welding is a highly efficient resistance welding process primarily used to join two or more metal sheets together by applying pressure and passing a high electrical current through the contact point. The heat
generated from the electrical resistance at the weld spot melts the material, forming a strong and durable bond once it cools. Commonly used in the automotive, aerospace, and appliance industries, spot welding offers numerous advantages such as high-speed operation, minimal material distortion, and cost-effectiveness for mass production. It is especially well-suited for thin sheet metals and plays a crucial role in manufacturing processes that demand precision, consistency, and structural integrity.
