Spot welding refers to a welding method in which a columnar electrode is used during welding to form a welding spot between the contact surfaces of two overlapping workpieces. During spot welding, pressure is applied to make the workpieces come in close contact, and then the current is switched on. Under the action of resistance heat, the contact parts of the workpieces are melted, and the solder joints are formed after cooling. Spot welding is mainly used for the welding of stamping parts of thin plate components with a thickness of less than 4mm, and is especially suitable for welding of automobile bodies, carriages, and aircraft fuselages. However, containers with sealing requirements cannot be welded.
Gas shielded welding refers to the welding method of carbon dioxide or argon gas protection, without welding rod and using welding wire. CO2 welding has high efficiency, and argon shielded welding mainly welds aluminum, titanium, stainless steel and other materials. Submerged arc welding is welding with welding wire and flux protection. The flux buried the arc like sand. Mainly used for welding thick plates. The hazard of gas shielded welding is that the arc and dust have a great impact on the health of the welder.
The argon arc welding technology is based on the principle of ordinary arc welding. It uses argon gas to protect the metal welding material. Through high current, the welding material is melted into a liquid on the welded substrate to form a molten pool, so that the welded metal and welding It is a welding technology in which the welding material reaches the metallurgical combination. Because the argon gas is continuously supplied during high-temperature fusion welding, the welding material cannot be in contact with oxygen in the air, thereby preventing the oxidation of the welding material, so it can weld stainless steel and iron hardware. .
Industrial robots are multi-joint robots or multi-degree-of-freedom machines used in the industrial field. They can perform work automatically. They are machines that achieve various functions through their own power and control. It can be commanded by humans or run in accordance with pre-programmed programs, and modern industrial robots can also act on the principles of artificial intelligence.
(1) Programmable. The further development of production automation is a flexible start. Industrial robots can be reprogrammed as the working environment changes. Therefore, it can play a good role in a flexible manufacturing process, small batches and multiple varieties, balanced and efficient. It is an important part of the flexible manufacturing system.
(2) Personification. Industrial robots have similar human walking, waist, arms, wrists and claws in mechanical structure. There is a computer in control. In addition, smart industrial robots have many human "biological sensors", such as skin-type contact sensors, force sensors, load sensors, vision sensors, acoustic sensors, and language functions. Sensors improve the ability of industrial robots to adapt to the surrounding environment.
(3) Universality. In addition to specially designed dedicated industrial robots, general industrial robots have better versatility when performing different tasks. For example, changing the end manipulators (claws, tools, etc.) of an industrial robot can perform different tasks.
(4) Industrial machinery technology involves a wide range of disciplines, and is a combination of mechanics and microelectronics-Mechatronics technolo
