The Relationship

Based on a large number of welding tests to automotive lightweight material by CO2 laser, the microstructures of welded joint were tested related to performance. on the condition of welding technology, the relationship between the lower critical power of stabile deep penetration welding and welding speed and the focus position is deduced, In a coaxial and side protective gas conditions, through the optimization of technological parameters laser deep penetration welding can effectively avoid heat affected zone of high strength zinc coated steel becomes soft, welded comprehensive quality has been effectively controlled. Zinc evaporates unsteadily, which leads to expansion of heat affected zone and reduction of welding stability, so in this paper effective measures are taken to control it. Experimental results show that a qualified welding quality can be obtained by optimized process parameters of laser welding and adopting argon as shielding gas.

Inverter Power Source

The article presents results of researches on manual arc welding efficiency development. It is proved that the arc welding inverter power source, compared with the diode rectifier, increases coefficient of transition of alloying elements into the weld joint; it also reduces the rate of alloying elements transition into slag and gaseous components and in addition reduces the harmful effects of welding on human organisms.

Inverter Power Source

In devices synchronized with electric mains and sensitive to interference (particularly to an inverter power source) it is expedient to also synchronize the power source. The paper describes a method of synchronizing the inverter power supply with the mains. The general aspects of the method are discussed in detail, and possible hardware implementations are considered. External factors and internal parameters affecting the quality of synchronization are analyzed. The results of practical implementation of this method for synchronization of klystron filament power supply are presented
