Abstract
The invention relates to a compound welding wire formed by wrapping a welding wire in a flux-cored welding wire. The compound welding wire comprises a flux-cored layer and a steel band layer and is characterized in that: a middle welding wire is wrapped in the flux-cored layer; and the middle welding wire accounts for 0.3 to 4.0 mass percent of the compound welding wire. The middle welding wire is an aluminum welding wire, an aluminum magnesium welding wire or an aluminum silicon welding wire. By the compound welding wire formed by wrapping the welding wire in the flux-cored welding wire, the problems that the coverage rate of welding slag is non-uniform and air holes exist in the welding slag can be solved.
Description
Technical field
The present invention relates to a kind of combined wire, wrap the combined wire of welding wire in especially a kind of flux-cored wire again, belong to welding field.
Background technology
The existing flux-cored wire of basic slag system that is used for is in manufacture process; owing to stirred restriction with dispensing devices; so far fail to solve the puzzlement that welding slag covered and existed pore; particularly aluminum content more is prone to this situation up to 0.6 ~ 2.0% the self-shield that is used for steel construction and petroleum pipeline and the welding wire of gas shiled.
All adopt when making this kind flux-cored wire and add aluminium powder or al-mg powder, its shape is not that sheet is exactly spherical.Because the density of aluminium powder or al-mg powder is than the metal powder (iron powder of other interpolation, manganese powder or alloyed powder: as the carbon ferromanganese powder) low, the granularity of adding the fluorite powder is all between 100 order to 325 orders, 3 kinds of powder (aluminium or al-mg powders, the metal or alloy powder, fluorite or other powder) mix the back just can be visual on the powder feeding band separating to aluminium or al-mg powder and other powder, add from the powder feeding band and drop to the U-shaped steel band, the powder that low density powder and density are high all can cause separating of powder in the speed of drop and steel band, it is inhomogeneous to make that aluminium powder or al-mg powder and other metal powder mix in drug core layer, and therefore the coverage rate of welding slag also can inhomogeneous or formation pore when welding.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the combined wire that wraps welding wire in a kind of flux-cored wire again is provided, can solve the inhomogeneous and leachy problem of coverage rate of welding slag.
According to technical scheme provided by the invention, wrap the combined wire of welding wire in the described flux-cored wire again, comprise steel belt layer and be positioned at the drug core layer of steel belt layer that feature is: welding wire in the middle of being enclosed with in described drug core layer; The quality of welding wire accounts for 0.3 ~ 4.0% of described combined wire gross mass in the middle of described.
Welding wire is aluminium welding wire, magnalium welding wire or aluminium silicon welding wire in the middle of described.
The present invention adopts parcel welding wire formation combined wire in drug core layer, has solved the inhomogeneous and leachy problem of coverage rate of welding slag.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
The flux-cored wire that is used for basic slag system of the present invention wraps the combined wire of welding wire again, comprises traditional drug core layer 1 and traditional steel belt layer 2, and drug core layer 1 is positioned at steel belt layer 2; Welding wire 3 in the middle of in described drug core layer 1, being enclosed with; The quality of welding wire 3 accounts for 0.3 ~ 4.0% of described combined wire gross mass in the middle of described;
Welding wire of the present invention is used for the acidic slag system and welds in the mode of self-shield or gas shiled.The present invention adopts the middle welding wire 3 formation combined wires of parcel in drug core layer 1, replaced and traditional mixed the mode that forms drug core layer with other metal dust with aluminium powder or al-mg powder, can not produce because aluminium powder or al-mg powder mix uneven phenomenon because of density less than other metal dust, solve the inhomogeneous and leachy problem of coverage rate of welding slag when welding.
The present invention is in manufacture process, the filler of traditional drug core layer 1 is put into feeding funnel by belt input steel band, simultaneously aluminium welding wire, magnalium welding wire or aluminium silicon welding wire are wrapped in and form middle welding wire 3 in the steel band, avoiding traditional aluminium powder that causes when in manufacture process, adding aluminium powder or al-mg powder inhomogeneous with the filler of drug core layer 1, the uneven problem of covering when welding that causes; The present invention wraps up middle welding wire 3 in drug core layer 1 after, just can not exist aluminium powder or al-mg powder and other to belong to the uneven problem of powder, when welding, because middle welding wire 3 is distributed in whole combined wire uniformly, the uneven problem of covering in the time of also can not forming welding.
Claims (2)
1. wrap the combined wire of welding wire in the flux-cored wire again, comprise steel belt layer (2) and be positioned at the drug core layer (1) of steel belt layer (2), it is characterized in that: welding wire (3) in the middle of in described drug core layer (1), being enclosed with; The quality of welding wire (3) accounts for 0.3 ~ 4.0% of described combined wire gross mass in the middle of described.
