In manual welding, this technique is usually essential for electronic operators, and it requires long-term practice. Generally, in operation, what is needed is exactlySoldering wireI wonder if everyone has mastered the five steps of welding and is clear about them. If you still don't quite understand, you can go on to learn more below

I. Preparations for manual welding.

Prepare the weldment and pay attention to removing the oxidation on the weldment Just slightly smooth the skin. Heat the soldering iron to the appropriate working temperature to keep the tip of the soldering iron clean and compare It should be palatable and the soldering iron tip should be placed in a better position. Also, wipe off the oxide scale on the surface of the solder and clean it thoroughly.

Ii. Heating

The tip of the soldering iron should be in contact with the part to be soldered. The entire soldered part, including the terminal to be soldered and the pad, should be heated evenly. Do not apply pressure or drag the soldering iron at will. The heating time should be approximately1~2Seconds.

Iii. Heat the soldering wire

After heating the workpiece to the welding temperature, the welding wire is sent to the weld point position of the workpiece to melt and wet the weld point.

Four. Remove the soldering wire

Melt the appropriate solder(When the welded parts have been completely absorbed and formed a thin layer of solder)After that, quickly remove the tin wire.

Five. Remove the soldering iron

After removing the solder wire, apply the flux(Containing welding wire)Before evaporation, the soldering iron should be removed quickly; otherwise, bad solder joints will be left.

Precautions for manual soldering

1The correct soldering method not only saves time but also prevents air pollution.

2Solder is used for connecting parts and for conducting and dissipating electricity, and is not used as a support point for force.

3Quality is established during the manufacturing process rather than through post-event quality control and maintenance. The most direct and economical way to achieve quality is through direct operation personnel, rather than through quality control and maintenance or post-event maintenance by engineering personnel.

4Welding is an art of skills, and its interest lies in everyone's attention to the welding work. Some people say that a tin worker with excellent welding skills should be called an artist of metals.

5Never touch the elements or solder the soldering iron tips. It's very hot(about400 ° C)And the burns it caused you.

6Work in a well-ventilated place. The smoke formed during soldering is mainly composed of molten solder and flux, which is quite irritating. Avoid inhalation by keeping your head to one side instead of upwards.
