Product Description

FN Series AC Rolling Seam Welding Machine Seam Welder
Main Features:
1.There are two standard Types: Transversal Seam Welding Machine and Longitudinal Seam Welding Machine;
2.Also one machine can be used as both transversal seam welding and longitudinal seam welding, only need to change the direction of upper welding wheel and the lower welding head and change the welding arm;
3.Welding wheel adopt three-phase infinitely adjustable-speed drives,convenient to welding speed adjusting,the two welding wheels have the same tangential speed;
4.Adopt adjustable stroke cylinder,to avoid collision damage between upper and lower welding wheel;
5.Driven one head and free the other head;

Difference
1. The upper and lower electrodes are not round rods but flat plates, and the working surface is flat. Usually, standard T-shaped grooves are provided for mounting bolts;
2, The welding machine power and electrode pressure is large, determined by the number of bumps or the area of the convex ring;
3. Generally, the electrode pressurization is only suitable for the direct press type, that is, the upper electrode is moved vertically to its working surface.
Advantage
1. Multiple solder joints can be soldered simultaneously in one welding cycle.
2. Since the current is dense in the bump and the current density is large, the welding can be performed with a small current, and a small nugget can be reliably formed.
3. The position of the projection welding is accurate and the dimensions are the same, so that the strength of the welding head is relatively uniform.
4, Can achieve the welding of different structural workpieces. Due to the current concentration, the disadvantage of the nugget offset during spot welding is overcome, and the thickness of the two workpieces during the projection welding can exceed 6 to 1.
5. Since the large-surface electrode is used and the bump is placed on one workpiece, the indentation of the exposed surface of the other workpiece can be minimized.
6. Compared with the spot welder, the oil, rust, oxide layer, layer and other coatings on the surface of the workpiece have less influence on the projection welding, but the clean surface can still obtain a more stable quality.
