Abstract

The invention discloses a welding fixing device. The welding fixing device comprises a welding fixing device body composed of a tray, a base and a supporting rod, wherein the top of the tray is fixedly connected with the bottom of the base; a groove is formed in the top of the base; the bottom of the inner wall of the groove is fixedly connected with the bottom of the supporting rod; the supporting rod is sleeved with a first welding piece; a second welding piece is connected into the first welding piece in a sliding manner; the supporting rod comprises a rod body; a fixing mechanism and a correcting mechanism are arranged in the rod body; the fixing mechanism comprises a rotating rod; and a sliding mechanism is arranged on the top of the rotating rod. The invention relates to the technical field of welding. The welding fixing device solves the problems that due to transverse welding, welding defects such as unsmooth welding seams on the surface of a welding part, uneven and full fillet filling, base metal corrosion, over-burning blackening, undercut (pipe opening burning), overlap height, cracks, air holes and impurities are caused.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding fixing device. Background technique [0002] A method of combining weldments by heating or pressure or both, and with or without filling materials, is called welding. Welding can not only solve the connection of various steel materials, but also solve non-ferrous metals such as aluminum and copper. The connection of special metal materials such as titanium and zirconium has been widely used in machinery manufacturing, shipbuilding, ocean development, automobile manufacturing, petrochemical industry, aerospace technology, atomic energy, electric power, electronic technology and construction and other departments. According to the statistics of industrially developed countries, the steel products used only after welding process account for about 45% of the total steel output every year. [0003] According to Chinese patent CN108453343A, a kind of welding equipment that ...
