Spot welding is a technique that is used to meld two metal surfaces together at a specific point. There are both advantages and disadvantages to the use of a spot welding machine. Determining the best machine for you will depend entirely on your needs and your situation.
What is Spot Welding?
Spot welding is a method that uses two copper electrodes to weld metal sheets together. These electrodes are placed on either side of the metal materials in the designated welding spot. An electrical current is then run through both surfaces. This creates heat caused by electricity resistance, which cements the material together.
Advantages of Spot Welding
Spot welding is a precise method, because it focuses on a specific spot of the material. This allows more control over how the material is melded together. Spot welding is a quick method, which can help speed up the efficiency of production. The concentrated electrical current requires less energy than other welding alternatives. Similarly, there is no dangerous open flame, so spot welding is a relatively safe welding method.
Disadvantages of Spot Welding
Spot welding may not be particularly strong because the metal is only adhered together in the one spot. The electrical current must also be at a particular level to work properly. If the current is too weak, the metal won’t meld together. If the current is too strong, it will melt a hole and damage the metal material.
Spot welding is an excellent method for precisely joining two metal sheets together. There are many benefits to using a spot welding machine, though the best method will depend on your situation and your welding needs.
