Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in further detail and embodiment:

[0032] see figure 1 , 2 , taking explosion + hot rolling TA1 / X65 titanium / pipeline steel clad plate as the welding test plate, in this example, the total thickness of TA1 / X65 titanium / pipeline steel clad plate is 16mm, of which the thickness of one side of X65 steel layer is 14mm, and TA1 pure titanium The thickness of one side of the layer is 2mm.

[0033] "U+V" compound groove is adopted, the depth and width of "U" groove on one side of TA1 pure titanium layer are 4-5mm and 5-6mm respectively, and the bottom of the groove is arc-shaped (such as figure 1 , 2 As shown), the depth and angle of the "V" groove on one side of the X65 steel layer are 11-12mm and 60-70° respectively. After the groove processing is completed, a pair of TA1 / X65 titanium / pipeline steel The composite plate is spot-welded from the side of the X65 steel layer at intervals of 50...

Abstract

The invention discloses a vanadium / copper solid solution transition connection-based welding process for a titanium-containing metal layer / pipeline steel layer composite board. The titanium-containing metal layer / pipeline steel layer composite board is formed in the way that an industrial pure titanium and titanium alloy board and a pipeline steel board are connected together by the explosive welding process and the connected boards are rolled by use of the controlled rolling and controlled cooling technology, so that an industrial pure titanium and titanium alloy layer is arranged on one side of the titanium-containing metal layer / pipeline steel layer composite board, and a pipeline steel layer is arranged on the other side. The welding process provided by the invention is simple in process implementation, can realize metallurgical butt-welding engineering production of the titanium-containing metal layer / pipeline steel layer composite board, enables a metallurgically connected seam to be relatively good in appearance and favorable in mechanical property index, and achieves reliable connection of the titanium-containing metal layer / pipeline steel layer composite board while guaranteeing the decay resistance of the titanium-containing metal layer / pipeline steel layer composite board.

Description

[0001] Technical field: [0002] The invention belongs to the field of welding technology, and in particular relates to a welding process of a titanium-containing metal layer / pipeline steel layer composite plate. [0003] Background technique: [0004] The titanium-containing metal layer / pipeline steel layer composite material combines the excellent corrosion resistance and light weight of titanium and titanium alloy materials with the excellent mechanical properties of pipeline steel, and can significantly reduce the cost of raw materials, and is widely used in mechanical chemical industry, seawater Desalination, vacuum evaporation, power plant desulfurization and oil and gas storage and transportation and other fields. Ordinary pipeline steel materials have served for a long time in the above-mentioned use occasions, and are extremely susceptible to highly corrosive components in the transport medium (such as SO 2 、H 2 S, Cl - , CO 2 etc.) act on the inner wall of the pip...
