The characteristics of resistance welding machine mainly include the following aspects:
Low voltage and high current: Resistance welding machine usually operates with low voltage (usually less than 12V) and high current (up to thousands of amperes). Low voltage ensures safe operation, while high current is used to generate enough heat for welding.
High power: Since resistance welding machine generates extremely high current in an instant, the power demand can reach hundreds of kilowatts. This high power output makes the welding process fast and efficient.
High efficiency: Resistance welding machine can complete the welding process in a short time, significantly improving production efficiency.
Accuracy: Through precise current and time control, resistance welding machine can ensure the stability and consistency of welding quality.
High degree of automation: Modern resistance welding machine is usually equipped with advanced control system and automation device, which can realize automatic welding and reduce manual intervention.
Wide range of application: Resistance welding machine is suitable for welding of various materials, including low carbon steel, stainless steel, aluminum alloy, etc., and is widely used in automobile manufacturing, aerospace, home appliance production and other fields.
High efficiency and energy saving: Resistance welding makes full use of the internal resistance heat of the workpiece, with low heat energy loss and high thermal efficiency, which is both energy-saving and electricity-saving.
Excellent weld quality: The weld of resistance welding solidifies and crystallizes under external pressure, and has forging characteristics, which effectively avoids defects such as shrinkage, looseness and cracks, and ensures the density of the weld.
Low cost advantage: No flux or gas protection is required during welding, and no filler metal is required to obtain high-quality welded joints, thereby reducing welding costs.
Small deformation and low stress: The heat is concentrated and the heating time is short, the heat-affected area is small, and the deformation and stress are also reduced. Usually, no correction or heat treatment is required after welding.
Simple operation: The resistance welding machine is easy to operate, easy to realize mechanized and automated production, and reduce labor intensity.
