The weld pool temperature of the welding robot is too high, how to adjust it? Does it feel like a cold wave is coming, minus 10 degrees can be seen everywhere, minus 30 degrees, experiencing the thrill of splashing water into ice is not unique to the Northeast. Do I need to pay attention to adjusting the temperature of the molten pool in such a cold day? The temperature of the weld pool of the welding robot is related to many factors, such as the welding time, the angle of the electrode, the diameter of the electrode, and so on.
When the welding robot is performing welding operations, when the angle between the electrode and the welding direction is 90 degrees, the arc is concentrated, the temperature of the molten pool is high, the angle is small, and the arc is scattered, so the temperature of the molten pool is low. The arc burning time and arc breaking frequency will affect the temperature of the molten pool.
When the wall of the weldment is relatively thin, the energy to withstand the arc heat is limited at this time. If the arc breaking frequency is slowed down at this time to reduce the temperature of the molten pool, shrinkage holes are likely to occur.
The welding manipulator robot can also select the welding current and the diameter of the welding workpiece according to the spatial position of the control weld and the welding level. When starting welding, the selected welding current and the diameter of the welding workpiece are relatively large, and the vertical position is supine. It is relatively small, so that the temperature of the molten pool can be well controlled, and the weld seam can be easily formed and beautiful.
