Welding Spot. The large amount of energy lets the weld happen without applying too much heat to other areas of the metal. Its also easy to do with a spot welding machine which has 2 electrode tongs about 6 inches 15 cm long that pass an electrical current through the metal to fuse them together.
Seam Welding Vs Spot Welding Seam Welding Spot Welding Welding from www.pinterest.com
Spot welding also known as resistance spot welding is a resistance welding process. The heat is normally generated directly at the interface by utilizing heat from the resistance of the metal to the flow of electric current. Through a concentrated pressure and high heat the two pieces are melted together and fused as they cool.
If you are a beginner welder or have been introduced to the world of welding recently you must have heard of spot welding.
Definition of Resistance Welding Resistance welding is a fusion welding process in which coalescence of metals is produced at the faying surfaces by the heat generated at the joint by the resistance of the work to the flow of electricity. The current and the heat generation are localized by the form of the electrodes. Through a concentrated pressure and high heat the two pieces are melted together and fused as they cool. If you are a beginner welder or have been introduced to the world of welding recently you must have heard of spot welding.
