    • A device (10) for isolating a surface for welding in an underwater location or in high fire risk areas. The device comprises a housing (27) which is arranged to be mounted on the surface and a sealing means (30) to provide a seal between the housing and the surface. The housing (27) is provided with a sealed inlet (50) for receiving a welding apparatus, a fluid inlet (32) for the passage of gas into the housing, and a fluid outlet (34) for the passage of gas and/or liquid out of the housing. A heating means (fig 3 is not figure) for providing heated gas to the fluid inlet is also provided. In use, an ingress of heated gas through the fluid inlet (32) facilitates an egress of gas and/or liquid, contained in a space defined by the housing and the surface, through the fluid outlet (34) in the housing. In this way an in situ dry gaseous environment is provided for welding the surface. The heating means (100) is provided upstream and comprises a space with heating elements (120) surrounded by insulation (130) with electrical inlets (122).
    • 一种用于在水下位置或高火险区域中隔离用于焊接的表面的装置(10)。 该装置包括被布置成安装在表面上的壳体(27)和用于在壳体和表面之间提供密封的密封装置(30)。 壳体(27)设置有用于接收焊接设备的密封入口(50),用于将气体通入壳体的流体入口(32)和用于气体和/或气体通过的流体出口(34) 液体离开房屋。 还提供了用于向流体入口提供加热气体的加热装置(图3不是图)。 在使用中,通过流体入口(32)进入加热气体有助于通过外壳和表面限定的空间中包含的气体和/或液体的出口通过壳体中的流体出口(34)。 以这种方式,提供了用于焊接表面的原位干燥气体环境。 加热装置(100)设置在上游,并且包括具有由具有电子入口(122)的绝缘体(130)包围的加热元件(120)的空间。
