Laser welding is the use of high energy laser pulse for local heating in a small area of the material, the energy of laser radiation through heat conduction to the internal diffusion of the material, the material melted to form a specific molten pool.It is a new kind of welding way, mainly for the welding of thin wall materials, precision parts, which can realize welding, butt welding, welding stack, seal welding, etc., deep than high, wide weld width is small, small heat affected zone, small deformation, welding speed, welding seam smooth, beautiful, without processing or simply processing after welding, high weld quality, no pores, can accurate control, focusing on small points of light, high positioning accuracy, easy to realize automation.Resistance weldingIt is used for welding thin metal parts, clamping between the two electrodes by a large current melting electrode contact surface, that is, through the workpiece resistance heat to perform welding.Easy deformation of workpiece, resistance welding through joint welded on both sides, and laser welding from the single side, only for resistance welding electrode should be regular maintenance to remove oxides and adhesion of the metal from the workpiece, the laser welding of thin metal lap joint does not contact with the workpiece, moreover beam can also enter the conventional welding and welding area, welding speed is fast.Argon arc weldingNon-consumable electrode and shielding gas are often used to weld thin workpiece, but the welding speed is slow, and the heat input is much larger than laser welding, easy to produce deformation.Plasma arc weldingIt is similar to argon arc, but its welding torch can produce compression arc to improve arc temperature and energy density. It is faster and deeper than argon arc welding, but inferior to laser welding.Electron beam weldingIt relies on a beam of accelerated high-energy density electron flow to impact the workpiece, in the workpiece surface very small dense product produces a huge amount of heat, forming a "hole" effect, so as to implement deep fusion welding.The main disadvantage of electron beam welding is the need for a high vacuum environment to prevent electron scattering, the equipment is complex, the size and shape of welding parts are limited by the vacuum chamber, the assembly quality of welding parts is strict, non-vacuum electron beam welding can also be implemented, but due to electron scattering and focusing is not good effect.Electron beam welding also has magnetic migration and X-ray problems, because the electron is charged, will be affected by magnetic field deflection, so it requires electron beam welding parts before welding demagnetization processing.X - rays are particularly strong at high pressure and need to be protected for operators.
Laser welding does not need a vacuum chamber and degaussing the workpiece before welding, it can be carried out in the atmosphere, there is no anti-x-ray problem, so can be online operation in the production line, also can be welding magnetic materials.
