Abstract
The invention discloses a kind of oxygen welding welding rod of cast aluminium.Formed by the casting of non-ferrous metals such as aluminium, silicon, iron, copper, manganese, magnesium, nickel, appearance does not add the oxygen welding welding rod of welding powder yet when not having coating to use.This welding rod can directly weld the cast alumin(i)um foundry goods of 100mm with interior thickness, but also welding aluminum alloy spare and aluminium sheet.Also need not any welding agent and solder flux during welding, smooth welded seam is smooth.Every index all meets national standard.
Description
The present invention relates to a kind of oxygen welding welding rod of aluminium, is a kind of oxygen welding welding rod that can weld aluminum casting.
The welding of the arc welding of aluminium and oxygen welding needs to make scaling powder with welding powder in the existing technology.These methods generally can only the aluminum component of throat thickness below 1.5cm.At Chinese patent CN1046110A " the low melting point aluminium soldering connects material " but in a kind of welding rod of the sheet-type of welding aluminum alloy at low temperatures weldment is disclosed, but defectives such as the pore that this welding rod can only the soldering aluminium casting occurs, crackle, aluminium casting that can not welding breaking.In the existing technology, thickness is that the above weldment of 1.5cm adopts the high argon arc welding of equipment investment, also needs welding powder and makes scaling powder, or use the aluminium alloy electrode that coating is arranged.In the said method, use coating and welding powder to need scarfing cinder after welding, this class welding rod because the effect of argon arc and electric arc easily produces splashes and floating phenomenon, thereby easily produces the rosin joint phenomenon when welding.Will find out the crack at postwelding once polishing, promptly welding rod does not have good the combination with mother metal.
The objective of the invention is at above-mentioned shortcoming, develop the oxygen welding welding rod that a kind of equipment investment is low, can directly weld cast alumin(i)um foundry goods, Al-alloy parts and aluminium sheet.
The solution of the present invention is as follows: welding rod is made in the scolder casting, and welding rod is made by aluminium and other several non-ferrous metals.Main part also has the magnesium and the nickel of a great deal of except that elements such as aluminium, copper, silicon, manganese, iron.Each component is pressed than fusing back cast molding in mould.This welding rod skin does not have the coating parcel, need not use welding powder, solder flux when welding yet, just welding that can weldment is firm, and smooth welded seam is smooth.Can directly weld in fracture place of cast alumin(i)um foundry goods.The thickness of cast alumin(i)um foundry goods all can firm smooth welding in 100mm.Every indexs such as the quality of weld seam, performance and tensile strength, yield strength, shock resistance all meet national requirements.Welding rod of the present invention owing to do not use welding powder and scaling powder, when welding, do not produce splash, floating phenomenon, welding rod and mother metal be combined in molten molten state formation alloying tissue down thereby smooth welded seam, smooth firm.Be a kind of easy and simple to handle, cost is low, the new type of electrode of good economic benefits and social benefit is arranged.
Below in conjunction with embodiment the present invention is illustrated:
Embodiment 1:
With following non-ferrous metal by being heated to 950 ℃ of fusings (percentage) than dropping into crucible:
Silicon 9.92 aluminium 85.68
Iron 0.67 magnesium 1.35
Copper 1.44 nickel 0.82
Manganese 0.032
Pour casting (temperature is 720-730 ℃) in the mould into, moulding is poured out.
Embodiment 2:
Each material ratio can be:
Silicon 8.51% aluminium 87.5%
Iron 0.56% magnesium 1.30%
Copper 1.48% nickel 0.80%
Manganese 0.032%
As can be seen, (GB3669-83) compares with existing arc welding electrode from above-mentioned component.Though components such as silicon, iron, copper, manganese, aluminium are also arranged in the component of welding rod, the ratio of welding rod copper silicon of the present invention is greatly greater than the ratio of the copper silicon in the arc welding electrode, and do not contain zinc, and other has unique a certain proportion of magnesium, nickel.Wherein silicon, magnesium, the intensity that makes welding rod at high proportion of copper, hardness is improved and the use of aluminum casting adapts.After testing, the intensity of welding rod (σ 0.2 ≈ 178MPa; σ b ≈ 199MPa) be higher than the intensity level of cast aluminium mother metal, but welding rod itself also have a certain toughness, satisfied the requirement of welding aluminum casting fully.
Claims (2)
1, a kind of Oxygeng welding rod for cast aluminium, form by non-ferrous metals such as silicon, iron, copper, manganese, aluminium, it is characterized in that its composition is except that non-ferrous metals such as above-mentioned silicon, iron, copper, manganese, aluminium, also have non-ferrous metals such as a certain proportion of magnesium, nickel, above-mentioned welding rod is to be formed by above-mentioned each non-ferrous metal casting, the appearance of welding rod does not have coating, and the component of each non-ferrous metal is:
Silicon 8-13% magnesium 0.5-1.5%
Iron 0.4-0.7% nickel 0.7-0.9%
Copper 1-1.5% aluminium 83-88%
Manganese 0.02-0.05%.
2, the oxygen welding welding rod of a kind of cast aluminium according to claim 1 is characterized in that the manufacture method of above-mentioned welding rod is:
In proportion above-mentioned each component is got the raw materials ready and under 900-1000 ℃ temperature, melt, pour cast molding in the mould into.
