At present, in addition to laser welding machines, there is also a cold welding machine that everyone is more familiar with. Hand-held laser welding machine and cold welding machine have three same characteristics: simple operation, small deformation, and beautiful welding seam. These three points are the common characteristics of the two machines, but which one is better, a handheld laser welding machine or a cold welding machine? In fact, the two are more pros and cons. Let's analyze the Leapion laser below.
1. The cold welding machine is called ESD in the world. It uses the high heat energy generated by the micro-electric instantaneous discharge to cladding the special welding wire to the damaged part of the workpiece, and it is firmly welded to the original base material. After welding, it only needs to be polished and polished. Post-processing.
2. The principle of the multi-function cold welding machine is: using a charging capacitor to discharge in an ultra-short time of 10-6 to 10-5 seconds in a cycle of 10-3 to 10-1 seconds. The contact part of the electrode material and the workpiece is instantly heated to 8000°C～10000°C, and the molten metal in the plasma state is metallurgically transferred to the surface of the workpiece.
1. The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.
2. Laser welding machines are divided into laser mold welding machines, automatic laser welding machines, laser spot welding machines, and optical fiber transmission laser welding machines according to their working methods.
1. The cold welding machine is mainly used to deposit, seal, repair and repair defects such as wear, scratches, pinholes, cracks, defect deformation, hardness reduction, trachoma, damage and other defects on the surface of metal workpieces.
2. The laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, sealing welding, etc. Laser welding has high aspect ratio, small welding seam width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, no or simple treatment after welding, high welding seam quality, no porosity, and can be Precise control, small focus spot, high positioning accuracy, easy to realize automation.
1. The cold welding machine is like a slower handheld laser welding machine in the form of work. It is a weld bead formed by continuous firing and pulse formation. Compared with laser welding, its speed will be slower.
2. However, if the requirements for the deformation of the product are more stringent, the cold welding machine is a more suitable machine. After all, the handheld laser welding pull welding has released countless laser pulses, and the residual temperature after welding is cold. It will be higher for welders.
1. The handheld laser welding machine has a scanning width when it is working, and its spot diameter is small, so when welding, it scans lines from one point to another, thus forming a weld bead.
2. A welding process can be pulled directly from top to bottom. Compared with cold welding machines, the welding speed of hand-held laser welding is relatively faster and more efficient. The welding process that passes by makes it more suitable. For mass welding of long straight seams.
It can be seen that handheld laser welding machines and cold welding machines have their own advantages. Hand-held laser welding and cold welding machines are both good products. Which machine to choose depends on our business needs, and the choice is right for you. The equipment required by the business is the most important.
