Mig welding mannipulator introduction
The welding robot is a mechatronic device that can be classified
according to the purpose, the controlled motion mode, and the
driving method.
According to the purpose, welding robots can be divided into the
following two categories, arc welidng robot and spot welding robot.
1) Arc welding robot
Arc welding robots are widely used in many industries such as
general machinery and metal structures.
The arc welding robot is a flexible welding system that includes
various arc welding attachments, not just a single machine that
carries the torch movement at a planned speed and attitude. In arc
welding operations, the torch should track the weld bead motion of
the workpiece and continuously fill the metal to form a weld.
Therefore, the stability of the speed and the accuracy of the
trajectory during the movement are two important indicators. Under
normal circumstances, the welding speed is about 5~5"/track
accuracy is about ±0.2mm. Since the attitude of the welding torch
also has a certain influence on the quality of the weld, the
adjustable range of the welding gun posture is as large as possible
while tracking the weld bead. Some other basic performance
requirements are as follows:
a) Set the welding conditions (current, voltage, speed, etc.):
b) Swing function.
c) The troublesome function of the groove.
d) Welding abnormal function detection.
e) Interface function of welding sensor (initial solder joint
inspection, bead tracking).

★ Noted
1. All measured data were obtained strictly according to the
national standard GB/T12642 (ISO9283) test method.
2. Test plan A represents the test using Leica laser tracker. The
measured data were all from the test report issued by Shanghai
Electrical Equipment Testing Co., Ltd. (National Robot Testing and
Evaluation Center Headquarters) (Report No. ROT18-0112), for the
measured data in the table, the worst value of all the results in
the test report was taken. The test plan B represents the test
using the Faro laser tracker. The measured data is from the our
test room, and the measured data is taken as the average value of
the batch test.
3. Because the welding robot is required to run faster as fast as
possible, the repeatability of the first performance index is
60m/min according
to the international test speed, and since the actual welding speed
will not exceed 2m/min, other performance indicators are based on
international the test speed is 2m/min.
4. Import reference data are from performance specifications or
public reports of international mainstream robots.
