Abstract :

 The main aim of this study is to show the characteristic changes obtained by the deflection of welding arc in the presence of external magnetic field. The magnetic field has been applied from various orientations upon the weld bead and its effects have been discussed accordingly. The welding process which has been considered under study is shielded metal arc welding. The material taken is mild steel and bar magnets of 10T intensity has been used. It has been seen that when magnets are placed in the longitudinal position of the weld bead, there is a tremendous deflection in welding arc while in transverse position of magnets, very less deflection is observed. This deflection in welding arc changes the weld bead properties. It is observed that weld pool penetration reduces while the weld bead width increases thereby affecting the parameters of the process. The results and conclusions are discussed as per the observations while the microstructures and hardness of parent materials are observed as well.
