Pulsed laser welding, mainly heat melting manner. Laser beam directly on the metal itself, the depth of penetration is limited, and its conductivity depends on the material temperature coefficient (conductivity temperature coefficient of the penetration depth is large) rather than the size of the laser power. Welding quality inspection, generally visual inspection and destructive testing of two ways. Visual inspection is shown in Figure 1 of the items tested. If the use of microscopy (microscope) photographs metallographic examination, you need to cut off part of the nuclear extract and grinding weld corrosion. However, if only after a visual inspection is not sufficient to conclude, be sure to look destructive experiments. Thegreen laster pointercompany is well known supplier ofgreen laster pointer. Destructive testing is usually carried out ripped experiment shown in Figure 3,4, welding base metal tear confirm (round hole on one side, the other side of the button-like residues appear) In addition, the instrument also has the use of stretch the tensile strength test method. Welding quality inspection, generally visual inspection and destructive testing of two ways. Visual inspection is shown in Figure 1 of the items tested. If the use of microscopy (microscope) photographs metallographic examination, you need to cut off part of the nuclear extract and grinding weld corrosion (see Figure 2). However, if only after a visual inspection is not sufficient to conclude, be sure to look destructive experiments. Destructive testing is usually carried out ripped experiment shown in Figure 3,4, welding base metal tear confirm (round hole on one side, the other side of the button-like residues appear). In addition, the instrument is also used for tensile strength tensile test method. The technology development ofGreen laser pointerhas been finished. Although the resistance spot welding method is best suited for mass production of welding means, but if the quality of mismanagement can cause huge losses. Currently, the line can not be achieved non-destructive weld quality inspection, it is necessary to strengthen the quality assurance management. Welding heat by contact between the electrode and the workpiece great impact resistance. Welding process, the pressure must remain constant, it is necessary to stress tester is often used for welding. Increase in the number of welding, the electrode surface will increase the wear and tear. Electrode surface roughness and cause splash marks caused by rough surface of the workpiece, the workpiece affect the appearance, it is necessary to prepare some more good ground electrode, according to the number of appropriate replacement of welding electrodes. Before using the new electrode with the workpiece void debug as well. The expert has noticed the technology difference ofgreen laster pointer. Electrode overheating will not only shorten the life of the electrode and the workpiece welding quality will lead to heterogeneity. By ignoring the workpiece thickness, coating thickness, metal composition and other changes caused by defective products welding phenomenon have occurred. The stability of the quality of the workpiece itself is also an important factor affecting the quality of welding. Current monitoring of the welding is essential. Changes affect the current main factors: fluctuations in supply voltage, welding machine overheating caused by overloading make use of current output reduction caused by bad contact with the workpiece current reduction, welding machines and poor performance. In order to prevent the causes of poor welding results, it is necessary to regularly monitor the welding current. If the welding current to ensure that monitoring can be more easily. The product feature will introduce some parameters ofgreen laster pointer. Found to affect the welding quality of the other claims of the reasons for the changes due to further improve the reliability of welding quality. At room temperature or under special conditions, welding, welding equipment installation simple. For example, the laser through the electromagnetic field, the beam does not shift; laser in a vacuum, air and a gas welding environment can, and can be glass or transparent material of the beam welding. The chip of this kind ofgreen laster pointerhas the long lifetime.
