作用
水下焊接与切割是水下工程结构的安装、维修施工中不可缺少的重要工艺手段。它们常被用于海上救捞、海洋能源、海洋采矿等海洋工程和大型水下设施的施工过程中。
方法
水下焊接有干法、湿法和局部干法三种。
干法焊接
这是采用大型气室罩住焊件、焊工在气室内施焊的方法,由于是在干燥气相中焊接,其安全性较好。在深度超过空气的潜入范围时,由于增加了空气环境中局部氧气的压力,容易产生火星。因此应在气室内使用惰性或半惰性气体。干法焊接时,焊工应穿戴防火、耐高温的防护服。
与湿法和局部干法焊接相比,干法焊接安全性好,但使用局限性很大,应用不普遍。
公司自创建以来,坚持以人为本,诚信经营,凭借高质量、效率、高信誉的作风赢得客户。多次承担急、难、险、重施工任务,多次与兄弟单位配合打捞沉船及若干沉水物资;青岛海湾大桥、水下堵漏等。历年来公司承建的工程均得到业主的好评。
Since its inception, the company has been adhering to the principle of 'people-oriented' and 'integrity management',水下切割水下打桩, and has won the customers by virtue of high quality, high efficiency and high credbility. Many times undertake urgent, ifficult, dangerous, heavy construction tasks, and many times with brother unit salvage the wreck and some submerged materials; Qingdao Bay Bridge, underwater plugging. Over the years, the company's construction projects have been praised by the owners.
