Defects in copper alloy laser welding1. Welding stressThe coefficient of linear expansion and shrinkage of copper are also relatively large. The coefficient of linear expansion of copper is 15% higher than that of iron, and the shrinkage rate is more than twice that of iron. In addition, copper and copper alloys have strong thermal conductivity, wh...

2024-03-0984120The ultraviolet laser marking machine is a cold processing method, where high-energy molecules in ultraviolet light directly detach the molecules on the metal or non-metal materials that need to be processed, causing the molecules to separate from the material.Electronic mobile phone components, LCD screen engraving QR codes and trademarks, ceram...
2024-03-0870510Steel can be said to be ubiquitous in daily life, but it has a disadvantage that it is prone to rust, especially those without paint or coating protection.Laser is another major invention of humanity since the 20th century, following nuclear energy, computers, and semiconductors. It is widely used in many fields and is known as the fastest knife, ...
2024-03-08859101. Examination of the entire bedBefore starting up every day, check the wiring of the laser cutting machine and the outer cover of the entire machine for any abnormalities. Start up the main power supply, power switch, voltage stabilizing equipment, air-cooled machine, laser, and auxiliary system to ensure that these overall components are intact a...
2024-03-071.1K10The running trajectory is incorrect, occasionally taking an extra half turn and deviating. Occasionally, there is an abnormality in not turning off the light.Problem analysis: Generally, it is a program problem. Determine whether different devices have been used and whether there is any unreasonable interaction between the customer's device...
2024-03-0787310The process flow of laser cutting is relatively simple, and the laser cutting path and parameter program are set in advance according to different products. Generally, holes are cut first, and then edges are cut. After the first piece debugging is qualified, cutting production can be directly carried out. However, it is not easy to cut the best qua...
2024-02-2779420Compared with other welding technologies, the main advantages of laser welding are:1. Fast speed, large depth, and small deformation.2. Welding can be carried out at room temperature or under special conditions, and the welding equipment is simple. For example, when a laser passes through an electromagnetic field, the beam will not shift; Laser can...
2024-02-2781410Many users who have a shallow understanding of laser welding equipment inevitably encounter many problems when choosing welding equipment, which will also be reflected in price differences. This difference is related to brand effect and machine configuration. The air cooling and water cooling we are discussing today will also affect the price of ha...
2024-02-2675910With the rapid development of laser marking technology and the deep integration of new information technology and machinery, laser marking has been widely used in various industries. It is recognized for marking company names, product models, production dates, production batch numbers, barcodes, and other information. The basic principles of flying...
2024-02-2271720Reducing costs and increasing efficiency is the ultimate goal pursued by enterprises. Throughout the history of steel industry technology, many major technological breakthroughs, such as converter steelmaking, continuous casting, and rolling, have been driven primarily by the desire to reduce costs. In today's highly mature metallurgical technology...
2024-02-21857101、 Precautions for starting a handheld laser welding machinePower on sequence: turn on the air switch → wait for three to five seconds for the water machine to start, then turn on the emergency stop and key switch → wait for the touch screen to enter the interface, set the welding parameters → click on the air valve to test whether t...
2024-02-19835101. It is not impossible to drill holes on the solder pad. If you are willing to spend money on small holes, the laser hole and plugging process should be fine;a. For BGA pads with a spacing of less than or equal to 0.5mm, they must be very dense and holes must be drilled on the pads; The difficulty and cost of PCB plate making process have increase...
2024-02-1967910Researchers at the University of Alto have adopted a new approach to create a metamaterial that exceeds the technological scope that has emerged so far. Unlike natural materials, metamaterials and metasurfaces can be customized to have specific electromagnetic properties, which means scientists can create materials with the characteristics required...
