When a welding machine is actually welding, more or less a certain amount of spatter will be generated. Positioner welding auxiliary equipment, suitable for welding position of rotary work, in order to obtain the ideal processing position and welding speed. The welding manipulator is generally composed of columns, beams, slewing mechanisms, trolleys and other components. A device that sends and maintains the welding head or welding torch in the position to be welded, or moves the flux along a specified trajectory at a selected welding speed. The roller frame is a device that drives the cylindrical (or conical) weldment to rotate by means of the friction between the weldment and the driving roller. As for the reason, it is mainly caused by the splash phenomenon of metallurgical reaction. For the welding operator, this spatter phenomenon occurs during the welding process, mainly due to the decomposition of the shielding gas at high temperature, which directly causes the expansion phenomenon.
When there are some high temperature environmental phenomena in our welding technology manipulator, the molten drop and the molten pool are actually caused by the gas that will be oxidized by the enterprise. In addition, for students, in terms of factors such as the bubbles that can be generated in the molten droplet or the molten pool and the factors that affect the violent expansion of the gas when it flows out of the molten droplet, this is actually the phenomenon that causes splashing.
The spatter phenomenon during the welding process of the welding machine is actually caused by extreme pressure. As far as the formation of spatter is concerned, it mainly depends on the polarity of the weld. When welding positive polarity, for positive ions, it is actually because the molten pool flies towards the droplet at the end of the welding wire, and the impact force in the machine is very large. It can be said that it is actually more likely to cause large particles to splash. In this case, reversed polarity is used, which means that the electrons hit the droplet, creating a smaller sputter.
Furthermore, for the spatter in the welding process of the welding robot, it is actually a spatter phenomenon caused by process factors. For short-circuit transition welding, improper adjustment of the inductance value of the DC circuit will lead to inappropriate dynamic characteristics of the power supply, resulting in short-circuiting of droplets.
Welding technology manipulators constantly appear spatter during the welding process. In fact, we may be due to the inappropriate selection of welding current and voltage in our country. Welding method Manipulator welding current passing through the transfer characteristics of the droplet actually has a relatively large impact on the enterprise. During long arc welding, when the problem of the wire diameter remains unchanged, the welding current gradually increases. At the same time, the droplet will become thinner, and some corresponding splashes will be greatly reduced when the droplet transitions.
