[Butt Welder]Principle of Butt Welder Using the resistance heat and a large amount of plastic deformation energy of the welding zone itself, the two separated metal atoms are close to the lattice distance to form a metal bond, and a sufficient amount of common grains are generated on the bonding surface to obtain the welding point and the welding seam. or butt joints.
Main use
For welding rods, pipes, profiles, etc. It can weld metal up to 16mm in diameter and 200mm square cut metal, suitable for use in various hardware industries, such as bicycles, fans, kitchen utensils and other products. It is a connection method with stable welding quality, high production efficiency, easy to realize mechanization and automation, and is widely used in automobile, aerospace, electronics, household appliances and other fields.

Butt welding Precautions when using the machine
1. Setting purpose
The operator of the butt welding machine is exposed to electric There are many opportunities, and the environment of electric welding operation is very different. Due to the poor condition of electric welding equipment, various casualties and accidents occur from time to time. Among them, there are many accidents caused by electric shock. This project is specially designed to avoid accidents.
2, Applicable solutions:
Any fixed, mobile welding that uses electricity All types of equipment are included in the evaluation plan.
3. Inspection method:
3.1 Welding machine power input terminal, one output There should be a screen guard at the end, and the screen guard should be reliable and useful.
3.2 The PE wire of the welding machine shell is connected correctly and the connection is reliable. The selection of wiring fault protection appliances should meet the grounding method of the power distribution system, as well as the needs of technical parameters such as welding equipment capacity, with correct wiring and reliable connection.
3.3 The insulation resistance between the primary and secondary coils of the welding transformer, and between the windings and the casing shall not be less than 1 megohm. It is necessary to shake the insulation resistance of the welding machine at least once every six months, and record it thoroughly.
3.4 The primary line of the welding machine must be three-core (four-core) copper-core rubber wire or multi-strand soft copper wire with excellent insulation, and the wiring length is not allowed to span 3 meters. If it is really necessary to use a longer wire, a first-level power control should be added within 3 meters of the welding machine side, and the power cord should be laid overhead. The primary wire of the welding machine should not be dragged on the ground. Not to be used across the passage on the ground.
3.5 The secondary line of the welding machine must be connected tightly without loosening, and the connectors on the secondary line are not allowed to span three. ) to avoid insulation aging due to prolonged overload.
3.6 The welding tongs shall comply with the relevant national regulations, and can ensure that the welding rod can be clamped at any slope, with excellent insulation, no defect in the heat insulation layer of the handle, and reliable connection between the welding tongs and the different wires. The connection should be simple and soft, easy to use, no overheating, no exposed conductors, and excellent clamp handle screen protection, which prevents the use of plant metal solutions, pipes, rails, etc. as secondary welding circuits.
3.7 The welding machine should be placed in a monotonous and ventilated location. If it is placed outdoors, in addition to the welding machine itself, it is necessary to provide additional protection against rain and snow. Clean, no accumulation of flammable and explosive materials.
4.2 For the safety evaluation of the electric welding machine, choose the negative clause evaluation checklist, and list 7 negative clauses to evaluate whether the electric welding machine is qualified. If any item does not meet the requirements, the electric welding machine being evaluated shall be regarded as unqualified.
Bump welding is to use the high-temperature arc generated when the positive and negative north and south poles are short-circuited in an instant to melt the solder on the electrode and the material to be welded to achieve the purpose of connecting them. The scheme of the electric welding machine is very simple. To put it bluntly, it is a high-power transformer that converts the 220V AC into a low-voltage, high-current power supply, either DC or AC.
The work piece is opposite to the chuck, and the two ends of the joint are pressed against each other, and a lot of current is led to the work piece through the chuck, and high temperature occurs through the contact surface. When the metal reaches the plastic state, the moving end is applied. Press with just the right amount of pressure to knead the ends together.
Butt welding machine maintenance
1. Daily maintenance content:
a) Check whether the soldering contacts have good electrical conductivity and no poor contact.
b) Check whether the connection of each line connector is reliable and there is no loose phenomenon.
c) Clean the dust of the butt welding machine.
2. Regular maintenance content:
a) Check each control circuit every six months; replace the aging circuit.
b) A comprehensive inspection and maintenance of the butt welding machine is conducted once a year.
