Dongguan precision machining manufacturers, what should Dongguan precision machining manufacturers pay attention to? The competition of precision machining manufacturers is becoming more and more fierce.

In the precision machining industry, competition has become fiercer in recent years. Many small companies and workshops have withdrawn from the market, and most of the remaining companies are still struggling unless they have transformed and innovated. In such an environment, how a precision machining factory allows salespersons to find customers and obtain a steady stream of orders requires us to give up our inherent thinking.

Welding: Also known as welding or welding, it is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways:

1. Fusion welding-heat the workpiece to be joined to partially melt it to form a molten pool. The molten pool will be joined after cooling and solidification. If necessary, a filler can be added. It is suitable for welding of various metals and alloys. , No need for pressure.
2. Pressure welding-the welding process must apply pressure to the weldment, which belongs to the processing of various metal materials and some metal materials.
3. Brazing-use a metal material with a lower melting point than the base metal as the brazing filler metal, use the liquid brazing filler metal to wet the base metal, fill the joint gap, and mutually diffuse with the base metal to realize the connection of the welded parts. It is suitable for welding processing of various materials, and also suitable for welding processing of different metals or dissimilar materials.
There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction and ultrasonic waves. In addition to being used in factories, welding can also be carried out in a variety of environments, such as the field, underwater and space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding. The possible harm to the human body caused by welding includes burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.
