Welding processing: industrial “tailor”, the basic processing method in the manufacturing industry
Welding, as an industrial “tailor”, is an important processing method in industrial production. Welding is a processing method that uses heating or pressurization, or both, and with or without filler materials to make the workpieces (same or different materials) achieve atomic or molecular bonding to form a permanent connection. Welding is an important processing method in the manufacturing industry. Welding technology has been widely used in many sectors of industrial production. The level of welding technology directly affects the quality, reliability, life, production cost and efficiency of the product. It plays an important role in promoting the development of industry and the technological progress of products and promoting the development of the national economy.
There are various ways to classify welding, and arc welding is currently the most widely used. 1) According to the specific principle of welding, welding equipment can be divided into fusion welding, pressure welding, brazing, etc. Among them, melting welding refers to the welding method in which the filler material (such as welding material, welding wire) and the base material are heated to a molten state together, a molten pool is formed at the joint, and the liquid metal in the molten pool is cooled and solidified to form a firm welding joint, so that the separated workpieces are connected into a whole. Among them, arc welding in melting welding is the most widely used welding method at present, which uses welding power to form an arc to provide energy for metal welding. 2) According to the degree of automation of the connection equipment, welding equipment can be divided into fully manual welding equipment, semi-automatic welding equipment and robot automated welding equipment. In the future, automated robot welding equipment will gradually replace traditional equipment.
Laser welding: It has both precision and efficiency advantages and meets the needs of new quality productivity
Laser welding is one of the laser melting welding processes. The principle of laser welding is to use a high-intensity laser beam to directly radiate to the metal surface, so that the welded part forms an energy-concentrated heat source area, so that the welded object is melted and a firm weld and weld are formed. According to different working principles and adapted to different processing scenarios, laser welding can be divided into five types: heat conduction welding, deep fusion welding composite welding, laser brazing and laser conduction welding.
Laser welding has the advantages of high precision/efficiency and easy integration of automation. It is a key link in the transformation of intelligent manufacturing. Compared with traditional welding technologies such as resistance welding, argon arc welding, and plasma, laser welding has a high penetration ratio, small thermal deformation, high efficiency, high processing accuracy, and is easier to integrate automation. It meets the development needs of intelligent, automated, green, and efficient new quality productivity. With the improvement of downstream companies’ requirements for processing accuracy and efficiency in the field of high-end precision manufacturing, coupled with the reduction of laser processing costs, laser welding may gradually replace traditional welding methods in the future.
