5 welding methods in audio tuning

1. Overlap welding: Overlap two objects to be welded together and weld directly. This method is the most commonly used, with high efficiency, time saving and trouble saving. However, the welding must be firm. If the welding is off, the objects to be welded will be disconnected immediately.

2. Hook welding: welding in which two objects are hooked together, such as two wires hooked together and then welded. This type of welding has a double insurance effect.

3. Plug welding: PCB component welding belongs to this type of welding. That is, the component leads and PCB holes are cleaned of dirt and plated with solder, and the component leads are passed through the PCB holes for welding.

4. Twist welding: twist the two objects to be welded together and then weld them. Twist welding is generally used in projects that require high precision and a high safety factor.

5. Exposed soldering: This is a type of plug soldering. To ensure that there is no cold soldering, the leads of the components to be soldered are passed through the holes of the circuit board, and the tips of the leads are exposed after soldering. This type of soldering is also a commonly used soldering method.
