Welding Advantage:
1. No drilling or extrusion required, you can buy electric welder at the price of electric drill, the price of welding rod is cheap, the cost is very low.
2. Welding simplifies the assembly process and increases production efficiency.
3.Joints are continuously fused at the atomic level, high structural strength and good sealing of the joint.
4. Easy to learn, low cost and widely used.
Precautions for use with electric soldering iron
1. Before soldering, cut the excess part of the part lead and tinning. If the surface of the part is oxidized and difficult to tin, use fine sandpaper or knife to clean the lead surface, use the soldering iron tip to dip the appropriate amount of rosin core solder to tin.
2. When soldering, please place a lead wire for the tinned parts where you are soldering, such as pad holes on printed circuit boards, various joints, sockets, and switch solders. The tip of the soldering iron is added to the appropriate amount of tin. The soldering part is retained for about 3 seconds, and when the soldering iron is removed, it forms a smooth solder joint.
3. After welding, please carefully observe the shape and appearance of the solder joint. The solder joints should be hemispherical and the height should be slightly smaller than the radius. Do not overinflate or too flat. Appearance must be smooth and uniform without any visible pores or dents. Otherwise, it is prone to wrong welding or wrong welding. If you are welding multiple parts leads at the same time, please pay more attention to the quality of the solder joints.
