The general purpose of this inquiry was to analyze plasma arc welding in the construction and repair sector of oil and gas pipelines in the country. The methodological approach assumed was quantitative, descriptive and field, with the support of a documentary study. The population consisted of 12 participants who gave their consent to participate in the study. The data collection technique used was the survey and the instrument was a questionnaire with dichotomous and multiple-choice questions. Data processing was carried out using descriptive statistics. Results: 83.3% of those surveyed have extensive experience in the area of ​​industrial welding; 33.3% of those surveyed indicated that covered electrode arc welding (SMAW) is the most used in the construction of oil and gas pipelines for the transportation of hydrocarbons, coinciding with 33.3%, who responded in favor of arc welding. gas shielded metal arc (GTAW); 66.7% of those surveyed reported that they are familiar with plasma arc welding (PAW) technology; 83.3% indicated that they are willing to participate in changes in order to incorporate plasma arc welding (PAW) technology more frequently to improve processes. Conclusion: Plasma arc welding (PAW) uses the same principles as TIG welding, but both the energy density and temperatures are much higher in this process, so it is mostly used in high quality joints, with welding technology. Precision applied at the point to be welded, it can be used to weld stainless steel or titanium pipes and tubes, so its application in the construction and/or repair of oil and gas pipelines to transport hydrocarbons can be advantageous to improve productivity, competitiveness and performance.
