1. When welding square welding nuts, the entire working environment must be ventilated. Otherwise, if the air is not circulated, harmful substances will be produced indoors, affecting people's health. And the protection net must be used during welding to prevent danger during welding.

2. During the welding process of square welding nuts, it is important to keep the angle between the welding part and the center line of the tungsten electrode between 80-85°, so as to better protect the welding pool.

3. The angle between the square welding nut filling wire and the welding surface must be within 10° to ensure that the entire nut surface is fully welded and prevent the nut accessories from loosening.

4. When welding square nuts, there are several chamfers on them, so during welding, the current will be concentrated at these chamfers to form a solid welding point. Therefore, when welding, the angle should be changed appropriately to prevent the current from being too large and damaging the chamfers.

5. If you are welding ordinary nuts, the welding current is required to be larger and the time is longer, so as to provide sufficient heat for the molten core to form a stable and firm weld.

Square weld nuts are widely used in power engineering, road traffic, furniture and building materials.
