Abstract
The utility model relates to a special welding bar for welding metal of an oxyhydrogen gas welding and cutting machine, comprising a steel wire strip 1. The essence is that the steel wire strip 1 is a low carbon steel or low manganese steel alloy steel wire strip of less than 0.1%, the surface of the steel wire strip 1 is plated with a layer of silicon and/or molybdenum metal 2, and the outside of the silicon and/or molybdenum metal layer 2 is provided with a layer of mixed substance 3 of calcium fluoride or calcium fluoride and ferromanganese powder. Using the structure of a plated layer, etc., when welding black metal, the utility model eliminates welding air holes on the whole and increases welding quality.
Description
The utility model belongs to the welding articles for use, and specifically it is the welding rod special for special that a kind of hydrogen-oxygen welding-cutting machine uses.
Hydrogen-oxygen welding-cutting machine is a kind of novel welding-cutting machine that occurred in recent years, and the welding rod that it adopts is conventional gas-welding rod or common iron wire.Because it is too high that the gaseous mixture that hydrogen-oxygen welding-cutting machine produces contains moisture, when carrying out the Summoning welding, cause the Summoning severe oxidation, hydrogen is at high temperature very active in addition, can be dissolved in liquid metal, so can form a large amount of pores after the welding position cooling, cause welding position intensity to descend.Yet there are no the welding rod special for special document that relevant hydrogen-oxygen welding-cutting machine is used by retrieval.
The purpose of this utility model provides a kind of welding rod that is specifically designed to hydrogen-oxygen welding-cutting machine, is used to weld Summoning, to improve welding quality.
The purpose of this utility model can reach by following structures.The utility model is made of the steel wire bar, and main points of the present utility model are that the steel wire bar is mild steel or the spiegeleisen steel steel wire bar below 0.1%, is coated with one deck silicon and/or molybdenum in the surface electrical of steel wire bar.So in use, the oxide that the silicon molybdenum at high temperature can the vat black metal, thus can significantly reduce air holes.
In order further to improve welding quality, the utility model can be surrounded by the compounding substances of one deck calcirm-fluoride or calcirm-fluoride and ferromanganese powder in the outside of silicon and/or molybdenum layer.So in use, calcirm-fluoride at high temperature generates hydrogen fluoride with Hydrogen Energy and directly is diffused in the air, thereby has has further reduced or eliminated the welding pore.Through experiment, its cladding thickness is best for the 1-1.5 millimeter.
The utility model has been owing to adopted structure such as electrodeposited coating, thereby makes the utility model when the welding Summoning, eliminated the welding pore substantially, improved welding quality greatly, thereby reached the purpose of this utility model.
Accompanying drawing has provided an embodiment of the present utility model, further specifies concrete structure of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is a cross-sectional view of the present utility model.Among the figure, 1 is the steel wire bar, is coated with one deck silicon molybdenum 2 in its surface electrical, is surrounded by the compounding substances 3 of one deck calcirm-fluoride and ferromanganese powder on silicon molybdenum 2.
The utility model welds out the face of weld forming, through doing pulling experiment, mother metal is broken and weld seam is intact, thereby be the utlity model has the wide prospect of utilizing.
Claims (3)
1, a kind of hydrogen-oxygen welding-cutting machine welding rod special for special that constitutes by steel wire bar (1), the steel wire bar (1) that is characterised in that of the present utility model is mild steel or the spiegeleisen steel steel wire bar below 0.1%, is coated with one deck silicon and/or molybdenum (2) in the surface electrical of steel wire bar (1).
