With a narrow-gap groove and welding using a conventional DC power supply, will magnetic deflection occur?

180 thickness, narrow-gap groove; welding with a conventional DC power supply causes magnetic deflection. 1. The effect of magnetic deflection can be reduced by changing the position of the ground wire, reducing the welding current, or altering the angle of the welding electrode. 2. An alternating current arc is used instead of a direct current arc; an alternating square-wave power supply is an ideal power source. 3. Reduce the welding current to decrease the magnetic field strength that causes magnetic deflection. 4. Change the travel angle of the welding rod by tilting it toward the side where the arc is offset. 5. Several welding ground wire connection points are reserved on the left and right workbenches, which are used to adjust the balance of the welding current and the uniform distribution of magnetic field lines. This helps to reduce the interference caused by magnetic deflection, ensures consistency in the arc’s shape and integrity, and results in a uniform and aesthetically pleasing weld shape.
