摘要
保护金属电弧焊是一种液体焊接工艺(熔焊),通过电极和工件之间的电弧产生热量。熔化形成的深度由热输入、电极角度和焊接方向决定。这项研究是在巴东理工学院机械工程实验室进行的。试验材料为低碳钢,厚10mm,长100mm,宽100mm。在工作材料表面进行焊接,多达4条焊缝,每条焊缝之间的距离为20mm。焊缝长度100mm。AWS E 6013电极的规格为直径3.2 mm。电压为30伏的交流SMAW焊机。焊接按工作图纸进行,焊接电流为85安培,电极角度为700和850,焊缝长度为100mm,焊接方向反向(电极吸焊液)。从焊接角度看,700电极角的焊接速度为2.51 mm/s, 850电极角的焊接速度为2.48 mm/s。每个电极角的热输入为1024.09 J/mm。在700电极角处,穿透率为10.85%,比850电极角处高1.14%。这表明电极角度影响熔深和焊缝宽度。
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 the workpiece. The depth of fusion formed is determined by the heat input, the electrode angle and the welding direction. The research was conducted in the Mechanical Engineering laboratory of the Padang Institute of Technology. The test material used is low carbon steel 10 mm thick, 100 mm long and 100 mm wide. Welding is carried out on the surface of the work material as many as 4 welding lines, each of which has a distance of 20 mm. Weld length 100 mm. The specifications of the AWS E 6013 electrode are 3.2 mm in diameter. AC SMAW welding machine with a voltage of 30 Volts. Welding is carried out according to the working drawings, the welding current is 85 Ampere, the electrode angles are 700 and 850, the weld length is 100 mm and the welding direction is reversed (the electrode attracts welding fluid). From the welding, the welding speed is 2.51 mm/s for the 700 electrode angle and 2.48 mm/s for the 850 electrode angle. The heat input for each electrode angle is 1024.09 J/mm. at the 700 electrode angle has a penetration presentation of 10.85%, 1.14% greater than the 850 electrode angle. This shows that the electrode angle affects the penetration depth and weld width.
