Precision machining industry has become more and more competitive in recent years, many small businesses and OEM workshops have withdrawn from the market stage, while the companies left behind unless they have been transformed and innovative, most are still struggling. In such an environment, precision machining factory how to make salesmen looking for customers, access to a steady stream of orders, we need to abandon the inherent thinking.
Welding: also known as fusion, fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by means of heat, high temperature or high pressure. Welding achieves the purpose of joining in three ways.
1, fusion welding - heating the workpiece to be joined so that it melts locally to form a molten pool, which is joined after it cools and solidifies, and can be assisted by adding molten filler if necessary, it is suitable for welding processing of various metals and alloys, and does not require pressure.
2、Pressure welding - the welding process must apply pressure to the welded parts, and it belongs to the processing of various metal materials and some metal materials.
3、Brazing - using metal materials with lower melting point than the base material as brazing material, using liquid brazing material to wet the base material, fill the joint gap and realize linking weldments by diffusing with each other with the base material. It is suitable for welding and processing of various materials, as well as for welding and processing of different metals or dissimilar materials.
There are various modern sources of welding energy, including gas flame, electric arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can be performed in a variety of environments, such as in the field, underwater and in space. Wherever welding is done, it can pose a hazard to the operator, so proper precautions must be taken when welding is performed. Possible injuries to the human body from welding include burns, electric shock, vision impairment, inhalation of toxic gases, and excessive UV exposure.
