200 liter Barrel Making Machine – Steel Barrel Seam Welding Process

The parameter adjustment points of the seam welding process of the steel drum welding seam welding process are more than that of the spot welding. Because in addition to the welding current, the electric pressure of the roller, and the welding time, the distance between the welding spots, the welding speed, the welding cycle, the surface size of the electric roller, the nominal quality of the material, etc. will affect the seam welding quality of the steel drum. . Therefore, when adjusting the parameters of the seam welding machine, the above factors should be taken into account. The characteristic is that the steel drum is welded with broken seams. After edging, the nominal thickness of the welding material should be guaranteed to be uniform. In order to eliminate the nominal residual adhesion and electrical A trim. The knurling drive should be adopted for the rolling, and the rollers are often turned and trimmed. In order to ensure the seam welding average and the nominal quality and electrical life of welding consumables.

Because the seam welding process has a larger current shunting than the spot welding process, the welding current is increased by 15-40% compared with the spot welding process, but excessive current may cause excessive pressure or burn through in the weld. Therefore, the specific value should depend on the conductivity, thickness or dot spacing (or amount of overlap) of the material. The welding speed determines the time for the contact area between the roller A and the plate to be in contact with a certain point of the two. The current is spread. Diversion size. The conduction effect of preheating and cooling and the ability to dissipate heat are all related to speed. The effect on seam welding quality is obvious. If the necessary joint strength is to be maintained in the faster welding speed zone, the welding current is increased. When the heat in the welding area is increased, the phenomenon of nominal overheating of the weldment and electrical A sticking loss will appear quickly, so it is difficult to try to increase the welding speed by increasing the current. Individually, the welding quality of the leaf can be obtained when the welding speed is low.
