Automatic welding equipment is used for all-position welding, and the welding execution part adopts the way of rotating auxiliary drive, which flexibly and reasonably changes the posture of the welding gun, which is conducive to all-position welding. At the same time, when driving the same welding execution parts, the motor power can also be reduced. In the application, the sensor at the welding position is installed on the final reduction shaft to detect the position of the welding torch. The automatic welding machine factory obtains relatively high control accuracy through this installation method.
In addition, with the help of this memory on the fully automatic welding equipment, some welding process parameters and welding seam tracking control programs are stored, and the welding process parameters are stored in the arc welding power source, so as to make the arc welding power source more advantageous. Make good use of it, through the cooperation of the two, effectively solve various quality problems that may occur in all-position automatic welding operations.
Second, the driving of the welding torch is carried out by a stepping motor (a stepping motor refers to an open-loop control element stepping motor that converts an electric pulse signal into an angular displacement or a linear displacement). The motor can be converted to digital. Effectively convert the input pulse type and convert it into a rotary motion. The component itself has high accuracy, not only does not cause drift problems, but also does not cause problems such as accumulated errors. Applying this component in all-position welding not only does not change the speed, but also the control frequency signal is more stable, and the torch displacement is more accurate.
Third, in the all-position welding operation, the combination of the welding head and the arc welding power source can not only achieve the purpose of all-position automatic welding, but also reduce the price of automatic welding equipment to a certain extent. In this way, not only automatic welding can be realized, but also semi-automatic welding can be performed by using an arc welding power source and a semi-automatic welding torch.
