| Abstract: | Based on A-TIG spot welding tests for carbon steel sheets of Q235A,the effect of activating flux on the properties of welding point is revealed.The testing results indicate that the penetration is increased significantly.With the flux,the appearance of weld spot is fine,the mechanical properties can be improved.The welding current,welding time and arc length would be optimal if the flux presented was used. |
