What is the difference between resistance welding and spot welding? Resistance welding 1. The characteristics and applications of resistance welding are the main welding methods of resistance welding. Resistance welding is a combination of welding parts, applying pressure through electrodes, and using current through the contact surface of the joint to extend the life of the spot welder. In order to more comprehensively introduce spot welders, ultrasonic metal welders, battery equipment, and lithium batteries Equipment, storage spot welder, automatic spot welder, AC spot welder, capacitor guide plate automatic spot welder, lithium battery pole piece automatic spot welder, power battery pole piece automatic spot welder, commutator automatic spot welder , AC parallel automatic spot welder, lithium battery pole piece automatic spot welder, lithium battery pole piece automatic spot welder and other products

What is the difference between resistance welding and spot welding? Force welding 1. Characteristics and applications of resistance welding Resistance welding is the main welding method for pressure welding. Resistance welding is a welding method in which pressure is applied through electrodes after the welding parts are combined, and resistance heat generated by the current passing through the contact surface and adjacent areas of the joint is used. The main features of resistance welding are low welding voltage (1~12V), large welding current (tens to thousands of amperes), and extremely short welding time (0.01~several seconds) to complete a joint. Applying mechanical pressure, the joints are welded under pressure. Resistance welding is widely used, and is especially important in the automotive and aircraft manufacturing industries. For example, new airliners have millions of solder joints. Resistance welding is used in aircraft, semiconductor components, and integrated circuit components, among others. Therefore, resistance welding is one of the important methods of welding. Resistance welding is divided into spot welding, seam welding and butt welding according to the process method.

Only some soldering is covered here. 2. Spot welding Spot welding is a resistance welding method in which the weldment is assembled, pressed between two electrodes, and the base metal is melted by resistance heat to form a solder joint. Spot welding is mostly used for thin plate connections, such as aircraft leather, aero-engine smokestacks, car cab shells, etc. (1) Spot welding machine The main components of spot welding machine include frame, welding transformer, electrode and electrode arm, pressurizing mechanism and cooling water circuit, etc. The welding transformer is a spot welding appliance, and its secondary has only one loop. The upper and lower electrodes and electrode arms are used to conduct welding current and also to transmit power. The cooling water passes through the transformer, electrodes and other parts to avoid heating. When welding, please pass the cooling water first, and then turn on the power switch.
