Let's briefly discuss the welding processes of spot welding and drag welding

Spot soldering refers to the process of soldering bit by bit with a sharp tip of a soldering iron. It requires high technical standards and a relatively slow soldering speed. It is mainly used for manual soldering iron soldering. Now, let's have the solder paste manufacturer explain it

There are mainly two types of welding processes, namely spot welding and drag welding. When conducting welding, one should first prepare the welding wire and soldering iron. The soldering iron tip should be kept clean and the soldered parts should be heated. It should be noted that if the flat part of the soldering iron tip is to be kept in contact with the workpiece with a large heat capacity, the quality of the soldering process must be ensured. The side or edge part of the soldering iron tip should be in contact with the solder component with a small heat capacity and keep the solder component heated evenly. When the workpiece is heated to the temperature of the molten solder, it willSolder wirePut in the solder joint, and the solder begins to melt and wet the solder joint. After melting a certain amount of solder, remove the welding wire.

Make the soldering iron fully contact the solder, even until the solder joint is completely moistened, and finally45°Move the soldering iron in the left and right directions. In the actual welding process, one should constantly practice and gradually improve their welding skills to achieve excellent welding quality.

Drag welding usually refers to the situation where the weld points are dense or are weld beads. The welding iron can be drag welded, which is faster than spot welding. Try to avoid the problem of slow welding or no welding. Drag welding requires the use of a stronger wire formula activity. When welding, the operation and production of the automatic welding machine are more efficient.

Drag welding is also a step in the welding process. This or no filler material can be chosen. By heating or pressurizing, or both, the weldment can achieve atomic bonding. On the circuit board andICEvenly apply rosin solution or flux on the pins. After the solder is completely melted, drag in one direction to complete the drag soldering.
