Effect of 70o and 85o Electrode Angles on Reverse Welding Techniques On Fusion Depth

Shielded Metal Arc Welding is a liquid welding process (fusion welding) that produces heat from an electric arc between the electrode and workpiece. The depth of fusion formed determined by input, angle direction. research was conducted in Mechanical Engineering laboratory Padang Institute Technology. test material used low carbon steel 10 mm thick, 100 long wide. carried out on surface work as many 4 lines, each which has distance 20 mm. Weld length specifications AWS E 6013 are 3.2 diameter. AC SMAW machine with voltage 30 Volts. according to working drawings, current 85 Ampere, angles 700 850, weld direction reversed (the attracts fluid). From welding, speed 2.51 mm/s for 2.48 850 angle. input 1024.09 J/mm. at penetration presentation 10.85%, 1.14% greater than This shows affects width.
