Since automation technology has been popularized to the welding field, there are two common welding systems, welding robot and welding machine. Although they are special mechanical equipment, there must be some differences. So the following will be welding robot and welding machine for comparison.
In terms of price, the special welding machine has more advantages than the welding robot, but most manufacturers will choose the welding robot, because the special welding machine is an automatic equipment developed for a specific product, which mostly uses servo x, y and Z axes, generally only welding round or straight welds.
The welding robot is not the same, it uses six servo control, very flexible, can three-dimensional irregular welding in any direction, so the price is relatively higher. However, the welding machine can be equipped with 4 to 5 welding heads, which is more efficient than the welding robot.
The difference between welding robot and special welding machine and the function of its external axis
It can be seen that the welding machine should be selected for the straight and round seams on the plane, but as long as the welding product changes its specification or shape, the welding machine will be useless. The welding robot just makes up for this deficiency. In this case, it only needs to reprogram and can be used again.
With the expansion of welding robot application, in addition to the basic configuration, welding robot sometimes adds one or more external axes. In other words, the external axis is actually an external action system connected with the welding robot, to cooperate with the robot's action, can meet the welding posture at the same time, and can also complete the whole welding more quickly, to achieve satisfactory results.
