The three factors affecting the welding of the concrete mesh welding machine: welding time, current intensity, and pressing force.
The welding of the concrete mesh welding machine adopts electric resistance welding, which belongs to multi-point row welding equipment. The transformer requires energy saving and high efficiency and accurate control;
The synchronous control technology is adopted in the welding time, so that the welding time and the sub-control welding time can be separately controlled, and multiple welding circuits can reduce the load of the welding transformer.
Since the heat generated by the resistor is proportional to the square of the current passing through, the current intensity is the most important factor in generating heat. The importance of the current intensity is not simply the magnitude of the welding current, and the current density is also important.
The welding pressure is an important factor in the heat generation. The welding machine pressure is the mechanical force applied to the steel mesh by the welding column head. The contact resistance is reduced by the pressure, and the resistance value is uniform, which can prevent local heating during welding and weld. The effect is even.
The welding time control of the concrete mesh welding machine is also an important factor in the generation of heat. The heat generated by the electric conduction is transferred to the welding by conduction. However, due to the different welding setting time, the high temperature of the welding point is different, and the welding results are different.
