Abstract
The utility model relates to a lower electrode for welding of steel grid screens plates, aiming at solving the problem with the prior art that steel grid welders currently can not be used to produce steel grid screen plates, and no welding electrode dedicated for steel grid screen plates is available. The technical proposal of the utility model is that: a lower electrode for welding of steel grid screen plates, characterized in that: the upper surface of the lower electrode is alternatively concave and convex. The utility model can be used to produce steel grid screen plates.
Description
Technical field: the utility model relates to a kind of welding electrode, particularly a kind of bottom electrode of weldable steel grid plate.
Background technology: the basic structure of existing steel grating welder comprises: oil cylinder, the source of welding current, top electrode and bottom electrode are set on the welding machine main body.Wherein, the bottom electrode cross section is a flat shape.This equipment only is suitable for welding the steel grating that horizontal stripe is a band steel.For horizontal stripe is band steel and bar steel steel grid plate at interval, because band steel is different with the thickness of bar steel, solder joint is in different plan-positions, therefore can't use steel grating welder to produce steel grid plate.Still there is not at present special steel grid plate welding electrode.
Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes a kind of steel grid plate, exists with the solution background technology: can't use steel grating welder to produce steel grid plate, and the problem of still not having special steel grid plate welding electrode at present.Solving this technical problem the technical scheme that is adopted is: a kind of bottom electrode of weldable steel grid plate is characterized in that being above the bottom electrode concave, convex interval shape.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopt technique scheme, utilize the bottom electrode of lower section for concave, convex shape at interval, make solder joint be in different plan-positions, can the steel grid plate of being made up of at interval different horizontal stripe of thickness and band steel be welded, finished the special equipment of producing steel grid plate.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: with reference to figure 1, a kind of bottom electrode of weldable steel grid plate is characterized in that being above the bottom electrode 2 concave, convex interval shape 1.
