Welding robot quality appraisal

welding robot is a mechanical equipment for automated welding operations manufactured through artificial intelligence technology, sensing technology, communication technology, etc. It has the characteristics of high efficiency, low cost, clear production cycle, high automation level, and stable product quality. It is widely used in engineering machinery manufacturing, automobile and auto parts manufacturing, coal mining industry, municipal construction, oil and gas pipelines, ship manufacturing and other fields to improve product competitiveness and ensure users' production efficiency.

Welding robots do not require human participation during the welding process. They are mechanical equipment that automatically welds workpieces and can be used to replace traditional welding. During the welding process, stable welding can be achieved and the speed of the welding production line can be increased. The biggest difference between welding robots and traditional welding is its intelligent control system.
Zhongke Testing provides welding robot quality appraisal services.

Welding robot quality identification can be analyzed from the following aspects:

1, identification of the presentation of welds

welding seam forming mainly includes: welding seam appearance dimensions, such as welding seam height, width, welding leg height, etc.; welding wave (grain) thickness, whether it is uniform; appearance defects, such as concave, undercut, welding nodule, lack of fusion, lack of penetration, slag inclusion, etc.; and spatter size, etc.

2. Identification of welding process

When adjusting the automatic welding process of industrial robots, the welding arc length and voltage knob must be reasonably adjusted according to the actual situation to ensure that there cannot be any short circuit in the sound of the arc pulse, thereby ensuring the quality of the automatic welding system. At the same time, in actual welding operations, in order to ensure welding quality, the reverse tilt method can also be used to tilt the welding gun reversely to 0-10°, and use a scientific and efficient advancement method to weld, thereby effectively controlling the welding effect.
