Embodiment example 1
[0053] Case 1 is implemented, and the swing arc welding seam tracking is carried out. A key technology of swing arc welding seam tracking is that a specific arc swing frequency is required, and the welding seam information is obtained by using the change of the welding current when the swing arc scans the welding seam. figure 1 , Figure 4 , Suspend the welding torch on the bracket, so that the welding torch can swing freely. Because only one-way swing is required, it is only necessary to connect a specific DC current to the No. 1' and No. 3' electromagnets, and use the DC control system to change this. The magnitude and direction of the direct current on the two electromagnets make the welding torch swing regularly in the direction of the X axis, and the swinging arc scans the welding seam information, and uses the Hall to collect the welding current signal to indirectly obtain the welding seam information. Because this device uses the DC magnetic field to indirectly contro...
Embodiment example 2
[0054] Case 2 is implemented, and arc additive manufacturing is carried out. Arc additive manufacturing technology has developed rapidly in recent years, and it is a key project of national industrial development. One of the key technologies of arc additive manufacturing is how to control the arc at a fixed point and directional control and adjust the local heat input. See figure 1 , Figure 4 , Figure 5 , Image 6 , select a specific torch, such as TIG torch, plasma torch, etc., set the torch such as figure 1 After the device is placed, the swing trajectory and deflection position of the welding torch can be selected first, and then the method of applying direct current can be selected. Adjustment, to clad a few layers at that position, only need to swing the welding torch several times in that direction; if more heat input is required in that direction, energize the corresponding electromagnet to deflect the welding torch to that angle; If more heat input is required...
