What are the differences between automatic variable diameter roll welding machines and cage winding machines?
Even the most durable equipment, with the longest lifespan, will see its efficiency greatly reduced if it is not properly "cared for" during daily use. So, what are the differences between automatic variable diameter roll welding machines and cage winding machines?

What are the differences between automatic variable diameter roll welding machines and cage winding machines?
1. Different levels of automation: The automation level of the cage welding machine is very high, and all work can be completed on the equipment. However, the reinforcing cage winding machine requires workers to pre-make reinforcing rings, and after welding, the reinforcing cage bars and reinforcing rings are made into a roughly cage-like shape.
2. Different precision: Because the cage roll welding machine uses numerical control, it is more precise during manufacturing, with small errors. However, according to the comparison of the thickness of the main bars and winding bars of the reinforcing cage to be made, some reinforcing cage winding machines will experience a reduction in diameter, and the winding error of the reinforcing bars will be slightly larger.
3. Different prices: Because the cage welding machine has higher automation and precision, its price is also higher. However, because the equipment is simple, the price of the reinforcing cage winding machine is relatively low.
4. Different lengths: Taking equipment of standard length as an example, reinforcing cages of 12 meters in length can be made. The roll cage welding machine occupies 27 meters, while the cage winding machine only occupies about 13 meters.
What are the advantages of automatic variable diameter roll welding machines?
1. When the molten nucleus is formed, it is always surrounded by a plastic ring, and the molten metal is isolated from the air.
2. Short heating time, concentrated heat, small heat affected zone, small deformation and stress.
3. No filler metals such as welding wire and welding rods, low welding cost.
4. Simple operation, easy to mechanize and automate, improving working conditions.
5. High productivity in mass production, no noise and toxic gases, can be combined with other manufacturing processes on the assembly line. However, flash butt welding requires spark isolation and isolation.
What are the disadvantages of automatic variable diameter roll welding machines?
1. The welding principle of roll welding machines and spot welding machines is the same, both belong to resistance welding technology. Their welding principle is through the combined action of heat and mechanical force, there is a process from pre-pressing, heating to cooling. Compared with medium-frequency spot welding machines, this process of medium-frequency roll welding machines is not so complete.
2. The weld of the medium-frequency roll welding machine is composed of overlapping weld spots, and the current distribution during welding is much more serious than spot welding, making it difficult to achieve roll welding for aluminum alloys, high-conductivity magnesium alloys, or thick plates.
3. The rolling electrode surface of the roll welding machine is easily damaged, leading to deterioration of the weld surface quality. Therefore, electrode dressing is a particularly noteworthy issue.

4. It is usually recommended that the roll electrode width of the roll welding machine is more than twice the longitudinal load area of the base material. The thinner the plate, the larger the ratio, so the damage to the base material and the heat affected zone are larger.
