When producing amusement equipment, it is necessary to combine various steel components. At this time, a welding technique is required. How to weld amusement equipment? 1. Welding current. Welding current is one of the main factors affecting welding quality and productivity. Increasing the current increases weld penetration and increases productivity. However, if the current is too high, the electrode core will overheat and the coating will peel off, which will cause defects such as undercuts, burn-through and welding, and the metal structure will also become too cold, if it is too cold, it can easily cause defects such as incomplete Defects such as penetrations and traps. 2. Arc voltage. The arc voltage mainly affects the weld melt width. The higher the voltage, the larger the melting width. The arc voltage is determined by the length of the arc. When the arc of the amusement equipment is longer, the arc voltage is higher, and when the arc is shorter, the arc voltage is lower. In the process of manual arc welding, the arc should not be too long, so the arc voltage is not high and the variation range is not large, generally 20-25V. 3. The diameter of the electrode. The diameter of the electrode is mainly selected according to the thickness of the workpiece to be welded. The thinner the workpiece, the thinner the electrode; the thicker the workpiece, the thicker the electrode. Electrodes with a diameter of 3-5mm are the most widely used. 4. Fast welding speed. Welding speed refers to the speed at which the electrode moves in the welding direction. The welding speed of manual arc welding is generally not specified, but it is controlled by the welder according to the size of the weld and the characteristics of the electrode. 5. The number of welding layers. In the case of manual arc welding of medium and heavy steel plates, multi-layer welding should be used. For the same thickness of steel, when other conditions are constant, the number of welded layers increases, which is beneficial to improve the plastic toughness of the welded joints of amusement equipment. The number of welding layers is determined according to actual experience. is the ratio of the thickness of the steel to the diameter of the electrode (rounded up).
