Application of Automatic Welding Machine On Large-Scale Pipeline Welding

At present, in the welding construction of large-diameter pipelines, the use of automatic welding machines for long-distance pipelines has become very common.

Pipeline automatic welding machines (also known as pipeline automatic welding equipment, on-site pipeline welding equipment, orbital automatic welding machine, wireless automatic welding equipment, water pipe automatic welding machine, pipeline welding machine, automatic pipeline welding machine, etc.) have a large number of applications in long-distance pipelines such as oil and natural gas, and its efficiency and welding quality are unmatched by manual welding and semi-automatic welding. In the construction of long-distance large-diameter pipelines, its advantages are more obvious, and its advantages are mainly reflected in the following points:

1. High efficiency

The automatic welding of long-distance pipelines is generally constructed by large-flow operation. Root welding is the first welding process. Only after the root welding is completed( with manual GTAW welding process), filling and cap welding can be carried out with an automatic welding machine( with GMAW/FCAW-GS welding process).

Compared with semi-automatic welding, automatic welding of long-distance pipelines in large flow operations can significantly improve construction efficiency, and the larger the diameter of the pipe, the more obvious the effect. The welding efficiency is basically 3-4 times that of traditional manual welding, and the advantages of high efficiency are obvious.

2. Safety

Fully automatic welding of pipelines can realize all-position welding of filling, cap, etc. The welding parameters can be directly programmed and entered into the wireless remote control, and fully automatic welding can be basically realized during the welding process. It can achieve a multi-angle smooth transition and precise welding, which ensures the safety of welds and the safety of construction personnel and provides the most basic guarantee for pipeline installation and operation.

3. Good welding quality

The automatic welding of long-distance pipelines also has the characteristics of good welding quality and good consistency of welding joint quality. For example, Tianjin Yixin automatic pipeline welding equipment was used in the construction of the Tianjin Nangang long-distance pipeline project, and AUT, RT, and DR non-destructive testing was used in the on-site inspection of the project. The first pass rate of the three detection methods is greater than 95%.

4. Reduce the labor intensity

Due to the high labor intensity of welders who work in the field for a long time, the degree of hard work is far greater than that of other types of work, and the income of such high-skilled workers is not optimistic. Less and less, without a substantial increase in wages, reducing labor intensity to attract the younger generation is a solution to the problem, and the automatic pipe welding machine can solve this problem. Taking the Tianjin Yixin YX-G168 model as an example, basic welders can easily get started after simple training, which greatly reduces the construction threshold of welders and solves the problems of difficult and expensive labor.
