Energy storage carbon steel copper-plated pointed large-head grounding projection welding studs with double steps. There are two types, namely thick type and thin type. The thread length is 15mm. The total length of the thick type is 20mm (the total length after welding, excluding the length of the small pointed tip). The total length of the thin type is 17.5mm (the total length after welding, excluding the length of the small pointed tip). Which stud welding process should be chosen to process the grounding studs for chassis and cabinets to make people feel more at ease? KaiChuang has two types of processes for grounding studs, namely the energy storage type process and the arc-drawing type process. The welding equipment required are KaiChuang CWTD energy storage stud welding machines and KaiChuang arc-drawing stud welding machines respectively. For the welding of grounding studs, it is recommended that you give priority to using the KaiChuang CWTD arc-drawing stud welding machine for welding. Because the nuts on the grounding studs are tightened by the customers themselves, and the tightening torque is not controlled by the cabinet manufacturers. If the studs are not welded firmly and fall off due to excessive tightening force, it will be very troublesome. Special personnel need to be dispatched to the site just for one welding stud. Now labor costs are high. When using the energy storage type, in order to be on the safe side, it is usually necessary to reinforce it with argon arc welding. This is very labor-consuming, and the quality is not necessarily guaranteed. If the reinforcement is missed, the studs may also fall off, which will directly affect the product quality and business reputation. Therefore, we recommend giving priority to using the KaiChuang CWTD arc-drawing stud welding machine to weld the grounding screws, which is fast, efficient and free from stud falling off. KaiChuang CWTD CD132PLUS European enhanced version capacitor energy storage welding machine has a built-in expert parameter database, which can automatically retrieve the best parameters according to the materials (cold plates, stainless steel plates, aluminum alloys, galvanized plates) and the diameter of the welding studs to ensure good welding quality every time. Using the KaiChuang CD-132PLUS energy storage welding machine to weld the grounding studs can also achieve good results.
