Description
Technical field
The invention belongs to field of material engineering technology, relate to the interconnection technique between the metal, particularly the interconnection technique that welding combines with splicing between the metal.
Background technology
The extensive use of new material be unable to do without advanced interconnection technique and carries out technical support and guarantee.Because the exploitation and the application of new material, connect inevitable between the dissimilar metal of heterogeneity, performance, but for difficult wlding material, adopt traditional handicraft to be difficult to realize good connection, the for example melting welding between magnesium/aluminium, secondly, properties of its welded joints is difficult to reach requirement of actual application, has limited the practical application of material.
Arc welding is the welding method of industrial extensive use, but for the welding between the dissimilar metal, because of being easy to generate intermetallic compound, is difficult to the effect that reaches good.Splicing is as a kind of interconnection technique, have fatigue behaviour good, advantage such as big failure load can be provided, in the bridging arrangement spare in fields such as Aero-Space, traffic, be widely used, but its stripping performance is poor, heat resistance difference and drawbacks limit such as easily aging its extensive application.For this reason, people adopt the glue welding technology, i.e. welding combines with splicing, improve the performance of joint, as the resistance spot-weld bonding, high energy beam glueds joint weldering, these two kinds of process using are directly carried out resistance spot welding or high energy beam welding to the welding position before or after adhesive curing, but these two kinds of welding methods all can not be filled welding material by butt welded seam/solder joint, there is welding defective such as subside, and to the requirement on machining accuracy height, the practical operation complexity, both sides are welded mother metal and are melted the formation weld seam simultaneously during these two kinds of technology welding simultaneously, when dissimilar metal connects, form intermetallic compound between the sheet material, affect the mechanical properties.
Summary of the invention
The purpose of this invention is to provide the technology that a kind of splicing and arc welding combine, can realize that effective overlap joint of welding-resistant metal, dissimilar metal connects, property of welded joint is significantly improved.
Technical scheme of the present invention is, a kind of intermetallic glueds joint the method for attachment that adds electric arc silk filling spot welding, earlier the faying surface of material to be connected is coated the consolidated structures adhesive, overlap, weld again, it is characterized in that, evenly scribble the glue-line that gross thickness is 0.02～1mm between the faying surface of material to be connected, the overlap joint back directly is the through hole of 3～10mm every 15～50mm apart from perforate at overlap along the seam direction, splits the place, hole with arc welding again and carries out two-sided silk filling spot-welded on; Before welding or welding back the overlap that the centre scribbles glue-line is heated to 50～500 ℃, and be incubated 10～180 minutes glue-line be cured.
Overlap is generally edge of materials, and lap width can be 15～40mm, can open an exhausting hole every 15～50mm distance along the seam direction behind the overlap joint, carries out two-sided silk filling spot-welded on again; When overlap at other positions, the length and width direction of material is the seam direction, when lap width was bigger, the 15～50mm distance of can being separated by was opened the above through hole of two rows and is welded.
The present invention splits bore portion with electric arc and carries out two-sided silk filling spot welding, the welding wire of fusing is inner mother metal with the fusing formation solder joint that is fused in the hole, thereby connect by the weldering metal, can realize between the metal of the same race or dissimilar metal, connection as magnesium alloy, aluminium alloy, titanium alloy, iron and steel etc. between the of the same race or dissimilar metal obtains the high-performance jointing.Can fill the welding wire identical or different during welding with mother metal.By filling welding material, the surface that can avoid the welding of resistance spot welding or high energy beam to be produced subsides, and when dissimilar metal welded, this method made the position of intermetallic deposits yields, transfer to sheet material inside by the stress raiser between the sheet material, therefore can effectively increase Joint Strength.And the method that spot welding combines with splicing can further improve the stability of joint, the reinforcing joint performance, and can the homogeneous state of stress, increase fatigue strength, reduce extent of corrosion, sealed test piece.
Welding heat source can adopt gas metal-arc welding thermal source, gas tungstun arc welding thermal source or plasma arc welding (PAW) thermal source.When adopting the gas metal-arc welding thermal source, welding condition can be arc current 20～300A, distance 2～20mm between nozzle and the workpiece, shield gas flow rate 5～20L/min, wire feed rate 3～12m/min; When adopting the gas tungstun arc welding thermal source, welding condition can be arc current 20～200A, arc length 1～5mm, shield gas flow rate 5～20L/min, wire feed rate 1～6m/min; When adopting the plasma arc welding (PAW) thermal source, welding condition can be arc current 40～500A, distance 3～15mm between nozzle and the workpiece; gas flow of ions amount 0.5～5L/min; electrode neck-in 2～6mm, shield gas flow rate 5～20L/min, wire feed rate 2～10m/min.
Can be coated with general consolidated structures adhesive between the two-layer material overlap to be welded, as epoxy resin, phenolic resins, Lauxite, furane resins, melamine-adhesives such as formaldehyde tree.
The present invention makes bearing load, fatigue strength, cutting performance, the stripping performance of welding structural element that raising by a relatively large margin all be arranged, thereby solve the connectivity problem of difficult weldering metal of the same race and dissimilar metal, reduce spillage of material, improve stock utilization, satisfy actual engineering demand.
