With the development of laser technology, more and more companies have begun to use advanced laser welding machines for processing, because laser welding technology has many advantages such as fast welding speed, large depth, and small deformation. In fact, in addition to laser welding technology, there are five other advanced welding technologies that are widely used. Let's analyze it with Leapion laser.
1) The principle of laser welding technology: laser radiation heats the surface to be processed, and the surface heat diffuses to the inside through heat conduction. By controlling the laser parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool;
2) Then fix the welded parts by spot welding and perform continuous laser welding;
3) Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding;
The power density is less than 10~10 W/cm is heat conduction welding. At this time, the penetration depth is shallow and the welding speed is slow; when the power density is greater than 10~10 W/cm, the metal surface is recessed into "holes" under the action of heat to form deep penetration welding. Features of fast welding speed and large aspect ratio;
4) Laser welding technology is widely used in high-precision manufacturing fields such as automobiles, ships, airplanes, and high-speed railways, which has brought significant improvements to people's quality of life, and has led the home appliance industry into the era of precision manufacturing.
1) Laser hybrid welding is a combination of laser beam welding and MIG welding technology to obtain the best welding effect, fast and weld bridging ability, and is the most advanced welding method currently.
2) The advantages of laser hybrid welding are: fast speed, small thermal deformation, small heat-affected area, and ensure the metal structure and mechanical properties of the weld.
3) In addition to the welding of automotive thin-plate structural parts, laser hybrid welding is also suitable for many other applications. For example: welding of shock absorber cylinder for automobile parts manufacturing and welding, welding of stainless steel large-scale display housing, etc.
1) Friction stir welding uses friction heat and plastic deformation heat as the welding heat source. The friction stir welding process involves a cylinder or other shape (such as a threaded cylinder) extending into the joint of the workpiece, and the high-speed rotation of the welding head causes it to rub against the welding workpiece material, thereby making the connection part The material temperature rises and softens.
2) Friction stir welding can realize welding between dissimilar materials, such as metals, ceramics, and plastics. Friction stir welding has high welding quality, is not easy to produce defects, and is easy to achieve mechanization, automation, stable quality, low cost and high efficiency.
1) Electron beam welding is a method of welding using the heat generated by accelerated and focused electron beam bombardment of weldments placed in vacuum or non-vacuum.
2) Electron beam welding is widely used in many industries such as aerospace, atomic energy, national defense and military industry, automobiles and electrical and electrical instruments because it has the advantages of no welding rod, not easy to oxidize, good process repeatability and small thermal deformation.
1) Working principle of ultrasonic metal welding:
It is a special method of connecting the same metal or dissimilar metals by using the mechanical vibration energy of the ultrasonic frequency. When metal is ultrasonically welded, neither electric current nor high-temperature heat source is applied to the workpiece, but under static pressure, the vibration energy of the frame is converted into friction work, deformation energy and limited temperature rise in the work room. The metallurgical bonding between the joints is a solid state welding that is achieved without the base material being melted.
2) The advantages of ultrasonic metal welding are that it is fast, energy-saving, high fusion strength, good conductivity, no sparks, and close to cold processing; the disadvantage is that the welded metal parts should not be too thick (generally less than or equal to 5mm), and the solder joints should not be too large. , Need to pressurize.
1) The principle of flash butt welding is to use a butt welding machine to make the two ends of the metal contact, through a low voltage strong current, after the metal is heated to a certain temperature and softened, the top end is axially pressurized to form a butt welded joint.
2) Rebar flash butt welding is to install two rebars in a butt joint form, and use the resistance heat generated by the welding current through the contact points of the two rebars to melt the metal at the contact points, produce strong splashes, and form flashes, accompanied by pungent odors. A pressure welding method that releases a small amount of molecules and quickly applies upsetting force.
