More manual work and low engineering quality and efficiency:
In the site processing, the site management is "dirty and bad", and there are safety risks such as fire. In addition, for the welding of pipelines, welding workers stand on the electric lift to carry out manual welding operations, labor intensity is high, low efficiency. The accuracy of pipeline cutting and pipeline welding is greatly affected by the technical level of workers, physical fitness, and other external subjective factors, which is difficult to ensure the consistency of pipeline welding quality, resulting in greater impact on project quality.
