Product Description

Automatic Steel Drum/Steel Barrel Longitudinal Resistance Seam Welding Machine

Product Description
Inverter automatic steel drum seam welder (hereinafter referred to as seam welder) is an important device for producing metal drums. Its working principle belongs to the scope of resistance welding: that is, after the workpieces are assembled, the electrode applies pressure and the current flows through the steel plate. The contact area of the overlap and the adjacent area generate resistance heat, thereby forming a series of overlapped nuggets to obtain an airtight weld.
The welding method adopted by this equipment is roll seam welding. The electrode is a cylindrical roller. Its width is larger than the overlap of the steel plate to control the thickness of the joint. Welding uses a large electrode pressure and continuous welding current. By controlling welding specifications, including parameters such as electrode pressure, welding current, and welding speed, stable welding quality can be obtained, and seam welding procedures for longitudinal welds with a diameter of 560mm to 571.6mm can be completed.
The operation flow of this equipment: Manually put the cut sheet on the pedal, and automatically transfer it to the automatic slitter. After being automatically conveyed into the machine and rolled into a cylindrical shape, the spot welding is not necessary, that is, the steel drum is longitudinally welded. Seam welding, automatic unloading.


Main Technical Parameters

5. Welding drum length(drum height): <1000mm
6. Welding Seam Overlap:2.5-3.5mm (High temperature and wear resistance, the thickness of the insert can be set)
7. Steel plate thickness:  0.6-1.5mmmm(The tolerance of long and short sides is within ±0.5, the tolerance of the diagonal line within ±1)
8. Compressed air pressure: 0.65 Mpa
9. Cooling water:80 L/min   0.25Mpa(optional chiller)

Process Flow:
Manually put the cut material on the pallet---Use the forklift (travel) on the feeding roller---automatic feeding by the suction cup---cut the edge (trimming) by the trimmer---to the rolling area- --Rolling---Drum walking---Welding area---Welding---Welding completed---Scissor tongue---Automatic unloading---Repeat the above actions

b: Longitudinal Seam Welding Machine
The seam welder is widely used to weld the steel strips into cylinder. When welding, the two working pieces are overlapped between two welding wheels and pressed together. Connect the power, the welding wheels turn. When the welding wheels turn onto the overlapped area, the high temperature between two wheels makes nugget on the cylinder. The welding current is generated by impulsing power source. The seam welder is used to weld simple thin wall carbon steel cylinder without coating and mid-steel and alloy steel plate.
