Mixing Truck Manufacturing Department Introduces End Flange Welding Robot

In order to meet the strict quality production requirements of mixing drums, the concrete mixing truck department of Zoomlion's Concrete Machinery Company has brought in a welding robot—an end flange welding machine. With the hard work of workshop staff and the equipment factory, installation and testing was recently completed, and the equipment has already formally been put into operation. 

The quality of end flange welding is directly related to the overall quality and service life of a concrete mixing truck, as it determines whether the mixing drum suffers from cracks, leakage, and other problems. If a problem does exist, it can even cause the drum to dislodge and fall from the mixing truck. Since the welding machine went into use, the manufacturing department's welding time has been cut by five minutes, which has increased efficiency by 25%, and the aesthetic appearance of welds has been improved. More importantly, the pass rate of ultrasonic inspections has risen to 100%, which represents a considerable improvement in quality.

Since the welding robot was put to use in production, it has been praised by operators in the workshop. One employee said, "With the machine, we no longer need to spend a long time bent over welding end flanges, and the intensity of our work has greatly decreased. At the end of the day, the quality of end flange welding has improved significantly." Before the introduction of the welding "robot," because the welding of end flanges was done manually, workers had to squat on front cones and use handheld welding torches. Because they were squatting for long periods, workers often suffered from lumbar strain. There also existed a risk of workers falling off the front cone and hurting themselves. The introduction of the welding robot to the concrete mixing truck manufacturing department has removed the need for employees squatting on front cones using handheld welding torches. Now it takes only a short time to activate the control buttons and for the welding robot to complete a precise, high-speed weld of an end flange. The robot has a number of advanced features and uses semi-automatic controls. It comes with a wired remote control, which can be operated from an electrical control box. This allows the operator and robot to coordinate the work efficiently. Compared to manual welding, the welding robot has significantly improved productivity and quality. 

With constant updating and improvements to production equipment, the quality of concrete mixing truck products is set to make new leaps and bounds, which will promote and enhance their market competitiveness and influence.
