★The application and characteristics of die welding machine
We must first understand the mold defects basically is the casting process of trachoma, stomata; work hardening and residual stress in the surface crack lead parts fatigue strength impact force; lead to errors in the process of machining the edge, corner defects, scratches and other types of factors. Compared with the traditional laser welding mold and advantage generally the application in other industries the advantages of similar, small thermal effect, the processing is not easy deformation, high accuracy, argon oxidation rate is low, the workpiece does not change color, in a small area of mould repair cracks, chipping, burr, sand hole and other parts of the complex angle than argon arc welding argon arc welding due to the advantages of traditional. The effect of welding heat Congenital defects lead to the defects that can hardly be welded
★The formulation process of die welding machine
After market research to understand the mold welding industry, we put forward the scheme of mould manufacturing machine, the basic idea is modified based on welding machine. The origin of several key part is: in order to adapt to the high strength, welding materials with high hardness, in order to improve the laser energy greatly; some of the mold the larger volume, the laser cavity made of cantilever; in order to ensure the continuity and uniformity of solder joints to increase the 2D worktable for placing mould, rather than the basic positioning spot welding machine hand.

★Adjustment of technological parameters of laser welding
● pulse energy
The pulse energy parameters reflecting in our spot welder is adjusting the voltage, which determines the size of the heating energy, the main effect of metal melting, as the energy increases, the solder joint weld depth and diameter increased, some we usually ignore the problem, more compact structure high voltage pulse width for relatively large joints, a lot of places we should learn from the experience of PT welding parameters (such as law material jewelry is the voltage of 400V, pulse width 2MS, if the guarantee basis by small voltage total energy output constant increasing pulse width, will be found after polishing after sometimes have pores,
● pulse width
The pulse width of the main penetration effect, when the pulse energy, pulse width adjustment can obtain a maximum penetration, this time for the optimum pulse width. It affects the penetration and influence of welding strength of solder and workpiece material, when the pulse width is the pulse energy increases in a certain range. The weld penetration and diameter also increases, so the joint strength also increased, but when the pulse width exceeds a certain value, the increase of heat loss caused by heat conduction on one hand; on the other hand, the strong evaporation led to the solder joint cross-sectional area decreases, the joint strength decreased. A lot of research and experiments of pulsed laser welding pulse
The defocusing amount can make the distribution of laser energy is relatively uniform, but also can obtain the appropriate power density. Although from positive and negative power density equal to corresponding plane defocus is equal however, resulting in two case of solder joint shape is not the same. When the power density of the negative defocus holes than the workpiece the surface of the high evaporation, more intense, therefore, can be used to increase the penetration of negative defocus;
The welding of thin material, is easy to use positive defocus. Because of deep penetration energy when a slight fluctuation is not obvious, so the relative energy is relatively stable, can also be understood as the negative defocus focus is not very sensitive, whereas positive defocus relative negative defocus focus more sensitive.
