This research is to study the performance of mechanical arm for welding cover gas. Types of welding aws a5.18 er 70s-6 that affect ss400 grade steel and steel s45c purpose was to study the effects of using different types of welding electrical potential difference. And the movement of the welding head Which is a factor in the trialPlate size 15 x 10 cm, 6 mm thick, is connected by the weld head is perpendicular to the plate
.The results of the physical components of a digital microscope to show the comparison of different welding current and weld surface.30 centimeters per minute And a voltage of 20 volt electrical steel sheets, the two species have the same thickness is 6 mm force a change in power from 90 to 200 amperes found that the welds. Ss400 grade steel90-160 amperes of electricity and steel grades ranging from 90-200 amperes s45c consistent weld. Size of weld penetration. The results of an experimental digital microscope It can be seen that the melting of the wire connecting the steel s45c.ss400 because a less porous found that
