Abstract
The utility model discloses a kind of gas shield welding structure adopting water-soluble paper diaphragm, it comprises welding work pieces and the diaphragm of tubulose; Diaphragm is arranged in the body of welding work pieces; Diaphragm is close to the welding ends of welding work pieces, and the periphery of diaphragm and the inboard wall of tube body of welding work pieces are tightly connected; During welding, two welding work pieces are staggered relatively, are full of inert gas between the diaphragm in two welding work pieces bodys.By utilizing a small amount of inert gas butt welding mouth to protect fully, welding quality improves.Water-soluble paper diaphragm, water soluble, environmentally safe, after having welded, without the need to being taken out by water-soluble paper diaphragm, easy to use, low cost, solves a long-distance transport pipes weldability difficult problem.
Description
Technical field
The utility model relates to a kind of mechanism of gas shielded arc welding, is related specifically to a kind of gas shield welding structure adopting water-soluble paper diaphragm.
Background technology
Gas shielded arc welding is the arc-welding method utilizing gas as electric arc medium and protect electric arc and weld zone.Gas shielded arc welding has the following advantages: 1. the observability in electric arc and molten bath is good, can regulate welding parameter in welding process according to molten bath situation; 2. welding process is easy to operate, and do not have slag or seldom have slag, postwelding does not need scarfing cinder substantially; 3. electric arc heat under the compression of shielding gas flow is concentrated, and speed of welding is very fast, and molten bath is less, and heat affected area is narrow, and weldment post welding distortion is little.
But traditional gas shielded arc welding, the gas shield of welding relies on steel pipe closed at both ends to carry out barrier gas and leaks, and production cost is high, energy consumption is high.
Utility model content
For solving the problem, the utility model provides a kind of gas shield welding structure adopting water-soluble paper diaphragm, and this structure is simple, easy to use, and cost is low, and aeration quantity is little, economic environmental protection.
For achieving the above object, a kind of gas shield welding structure adopting water-soluble paper diaphragm disclosed in the utility model, it comprises welding work pieces and the diaphragm of tubulose; Described diaphragm is arranged in the body of welding work pieces; Described diaphragm is close to the welding ends of welding work pieces, and the periphery of diaphragm and the inboard wall of tube body of welding work pieces are tightly connected; During welding, two welding work pieces are staggered relatively, are full of inert gas between the diaphragm in two welding work pieces bodys.
Further, described diaphragm is water-soluble paper diaphragm.
Further, during welding, two described welding work pieces are staggered relatively, and the joint of two welding work pieces is provided with annular weld bond; Described diaphragm is arranged on described annular weld bond both sides.
Further, described annular weld bond is Y type or V-type with regard to cross section.
By utilizing a small amount of inert gas butt welding mouth to protect fully, welding quality improves.Water-soluble paper diaphragm, water soluble, environmentally safe, after having welded, without the need to being taken out by water-soluble paper diaphragm, easy to use, low cost, solves a long-distance transport pipes weldability difficult problem.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the gas shield welding structure adopting water-soluble paper diaphragm in embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, a kind of gas shield welding structure adopting water-soluble paper diaphragm, it comprises welding work pieces 1 and the diaphragm 3 of tubulose; Diaphragm 3 is arranged in the body of welding work pieces 1; Diaphragm 3 is close to the welding ends of welding work pieces 3, and the periphery of diaphragm 1 and the inboard wall of tube body of welding work pieces 3 are tightly connected; During welding, two welding work pieces 3 are staggered relatively, are full of inert gas 4 between the diaphragm 1 in two welding work pieces 3 bodys.During welding, two welding work pieces 3 are staggered relatively, and the joint of two welding work pieces 3 is provided with annular weld bond 2; Diaphragm 1 is arranged on annular weld bond 2 both sides.Annular weld bond 2 is Y type with regard to cross section.
Wherein, diaphragm 1 is the water-soluble paper diaphragm be made up of soluble polyvinyl alcohol fiber.
Below only describe several preferred embodiments of the application by reference to the accompanying drawings, but the application is not limited thereto, every those of ordinary skill in the art are under the spirit not departing from the application, and any improvement made and/or distortion, all belong to the protection domain of the application.
