Welding process requirements for mig welding manipulator
1. Highly flexible motion system. It can ensure the movement of the
welding gun to achieve various space trajectories, and can
constantly adjust the space attitude of the welding torch during
the movement. Therefore, the motion system has at least 5 to 6
degrees of freedom.
2. A control system with high precision. Positioning accuracy, spot
welding robot should reach ± 1 mm. The arc welding robot should
be at least ±0.5 mm and its parameter control accuracy should be
1%.
3. The capacity of the teaching memory at least guarantees that the
robot can work continuously for one hour.
The spot welding robot should store at least 200 to 1000 point
positions.
The arc welding robot should be able to store at least 5,000 to
10,000 points.
4. The welding parameters associated with the motion can be set and
reproduced. And welding aids (such as fixtures, turntables, etc.)
exchange in - place information.
5. Work space that can be in place.
6. Its teaching system can easily teach the welding robot
subjective error the difference is limited to a small amount.
7. The control device has high anti-interference ability and
reliability. Can work normally in a production environment,
The fault is less than 1 time / 1000 hours.
8. Reliable self - protection and self - checking system. For
example, when the wire or electrode "sticks" to the workpiece
The system can automatically power off immediately. For another
example, the robot automatically moves forward and automatically re
- ignitions when the welding power source is not turned on or the
welding arc is not established.
Welding power source choice for mig welding manipulator
Robot manufacturers at home and abroad have their own specific matching welding equipment. The corresponding interface boards have been inserted into these welding equipments, so there is no additional interface box in the arc welding robot system.
With the increasing application of stainless steel welding and
aluminum welding, domestic and foreign welding equipment tends to
develop in the direction of digital welding machines.
In the arc welding robot working cycle, the arc time accounts for a
large proportion. Therefore, when selecting the welding power
source, the power supply capacity should generally be determined
according to the continuous rate of 100%. The wire feeding
mechanism can be mounted on the upper arm of the robot or outside
the robot. The former hose between the welding torch and the wire
feeder is shorter, which is beneficial to maintain the stability of
the wire feeding, while the latter hose headmaster, when the robot
Sending the welding torch to certain positions, so that the hose is
in a multi-bend state, will seriously affect the quality of the
wire feeding. Therefore, the wire feeding machine must be installed
in such a way as to ensure the stability of the wire feeding.
