国家发展对石油的需求越来越大,带动了海洋石油工业的快速发展,海洋工程结构类型日益丰富,海洋生产设备日趋复杂,海底焊接技术已成为海洋石油工程中进行设备装配和修缮的关键性技术。本文综述了传统水下焊接技术、水下焊接的新技术,并就水下焊接技术的发展趋势提出了一些看法。 The increasing demand for oil from national development has led to the rapid development of the offshore oil industry. The types of marine engineering are becoming increasingly rich. The production of marine equipment is becoming more and more complicated. Seawater welding technology has become the key to equipment assembly and repair in offshore oil engineering technology. This article summarizes the traditional underwater welding technology, underwater welding new technology, and gives some opinions on the development trend of underwater welding technology.
