摘要：
The objective of this research is to find the parameters in gas metal arc welding for the application of steel. The force and velocity with which the droplet falls in the weld pool during the welding process were analysed. The effects of different shielding gases used in the welding process were studied by varying the percentage of different shielding gases during the welding process. During the welding process different types of forces affected the droplet which was calculated by modified force balance model (MFBM) analytically. Experimentation was conducted to observe the effect of the shielding gas and validate the analytical model. Effect of pure argon, different percentage of O-2 and CO2 mixed with the argon were observed and compared the result with the experimental data.
