There are many types of numerical control welding equipment, but they are basically the same. They include four main components: control equipment, control equipment, power supply equipment and process support equipment. Before use, at least ensure that these supporting parts of the NC welding equipment are intact and normal. In addition, what should you pay attention to?
Numerical control welding equipment is a kind of equipment used with welding roller frame, welding positioner and other products. With it, you can send and fix the welding equipment at the position to be welded, or move along the specified path at the selected welding speed. Provide a good foundation for correct welding.
When using numerical control welding equipment, it must be reliably positioned and clamped, which can prevent and reduce welding deformation and place the workpiece in the ideal welding position. This is useful for ensuring that the welding is well formed and improving the welding speed. of
For numerical control welding equipment, general standardized welding support equipment should be used as far as possible to help give full play to the efficiency of the manipulator; Of course, the selected CNC welding equipment must have better manufacturing process and better high mechanical effect, otherwise it will not be able to be used normally.
When using numerical control welding equipment, there are high requirements for the selection of supporting equipment, especially the rigidity of the equipment and the shape and dimensional accuracy of the equipment. At the beginning of welding, heat conduction, conductivity, magnetic insulation and insulation have specific requirements for welding equipment.
If the welding positioner must weld a large weld between thick plates, and there is almost no space between the two metal plates before welding, the parts cannot be moved during the whole welding process, etc. once the whole weld is completely cooled and contracted, all the shrinkage stress will be directly absorbed by the weld seam. Therefore, if the weld seam is under great stress, the shrinkage stress may lead to serious crack welding between the welds.
Shandong numerical control welding equipment manufacturer believes that cracks are easy to appear especially in the one-time welding between two metal plates, but if the gap between the two metal plates is relatively small, when the welding shrinks, we can slightly move the lower metal plate to reduce the reduction of the integrity gap, which will also lead to the appropriate reduction of the transverse stress of the whole weld. If you want to weld a large, relatively thick steel plate, the gap of the entire joint between the two metal plates should be 0.8 mm, but if circumstances permit, the gap of the joint must be 1.6 mm.
