摘要： An improved method and apparatus for the submerged arc surfacing of metallic work pieces with metal electrode strips melting in an electric arc while forming welding beads upon the work piece. The apparatus comprises a work piece which is to be surfaced, an electrode strip comprising the cladding material, means operative to move the strip and work piece relative to one another, a DC source, the opposite poles of which are connected to the electrode strip and the work piece, an electro-magnetic means having poles of opposite polarity operatively positioned at opposite sides of the electrode strip and adjacent the pool of molten flux and molten metal lying behind the electrode strip. The current to the electro-magnetic means is pulsed to thereby cause an agitation of the molten slag and weld deposit thereby resulting in a weld bead of extremely high quality, uniform thickness and also a defect-free tie-in between adjacent weld beads.

摘要： A method and apparatus is disclosed for feeding welding flux to both the leading and trailing sides of the strip electrode used in a submerged arc strip cladding process. In order to prevent distortion of the bead shape the pressure due to the weight of the flux burden is controlled to be less in the region of the molten metal and slag pools lying directly behind the welding arc. The flux burden is caused to increase from a first depth directly behind the strip to a maximum depth at the trailing edge of the weld crater region where the quantity of liquid metal and liquid slag is a minimum.

摘要： An apparatus for automatically seal welding a tube to the inside surface of a header. A mandrel concentrically supports the apparatus from the tube to be welded and carries a rotating support which in turn carries a welding torch. Electric motors for rotating and oscillating the torch are located with their axis parallel to that of the mandrel. Weld spatter shields protect the interior of the tube and also the various drive mechanisms.

摘要： A method and apparatus for removing a hollow tube from a tube sheet in which the tube is held by expansive forces in the tube. A GTA arc is established between an electrode and the interior tube wall. The arc parameters are such that it melts partially through the tube wall and the arc is then translated in a desired pattern of movement along the length of the tube contained in the tube sheet. Upon re-solidfication of the melted part of the tube the compressive forces of solidification shrinkage and thermal contraction result in a reduction of the tube diameter. Apparatus is disclosed for carrying out the method which, through a dual drive arrangement, is capable of producing a variety of weld head translation paths.
