Description
Technical field
The utility model belongs to welder field, and in particular to the welding dress between the larger foreign material of performance difference
Put, it is adaptable to which the storeroom that physical and chemical performance differs greatly is (for example：Aluminium/steel, aluminium/stainless steel, TiAl-base alloy/steel, tungsten are closed
Gold/steel, titanium alloy/steel, titanium alloy/stainless steel etc.) welding.
Background technology
In recent years, composite widely should because its good performance has in every profession and trade as obtained in welding dissimilar materials
Use demand.Foreign material wherein larger to some performance differences, such as aluminium/steel, aluminium/stainless steel, TiAl-base alloy/steel, tungsten are closed
Gold/steel, titanium alloy/steel, titanium alloy/stainless steel etc., due to fusing point, hardness, pyroconductivity, the coefficient of expansion, the chemistry of storeroom
The aspects such as composition differ greatly so that mutual solubility is low, joint residual stress big, the easy harmful brittlement phase of generation, causes joint
The problems such as low intensity, the technical bottleneck as the popularization and application for limiting these composites.Therefore rational preparation technology is selected
Method or welder, obtain the task of top priority that excellent welding point is the research of these composites.
At present, the welding method to foreign material mainly has：Laser Welding, electron beam weldering, soldering, diffusion welding (DW), friction welding (FW) etc..
Laser Welding and electron beam weldering belong to melting welding, although production efficiency is high, but stomata, crackle, segregation and brittlement phase easily occurs in joint.Pricker
The solder of weldering needs special development, and strength of joint is influenceed by solder, low strength, and may not apply to hot environment.Solid phase expands
Scattered weldering weld interval is long, low production efficiency, and the generation of brittlement phase is very big by welding temperature and time effects.Plus intermediate layer
Instant liquid-phase diffusion welding, though energy improve production efficiency, the most of needs of intermediate layer needed for obtaining good joint are specially
Prepare, complex process.
Friction welding (FW) (mainly including agitating friction weldering and flywheel friction welding, the technical program is based on flywheel friction welding) production
Efficiency high, because interface is non-fusible, joint is difficult to generate brittlement phase, there is larger advantage in terms of welding dissimilar materials.By institute
Difference in terms of two kinds of material properties of weldering, during using friction welding (FW), solder side temperature generally between two kinds of material melting points, this
Interface temperature overheat in low-melting material one end on solder side is allowed for, the thermoplasticity metal of generation is more, and fusing point material high
Not enough, the plastic deformation layer of generation is thin for one end temperature.
It is well known that the essence of friction welding (FW) is good to be formed by interface metal plastic deformation, recrystallization and elements diffusion
Good joint.When solder side temperature is not enough to be formed enough thermal deformation metal levels, recrystallization and elements diffusion be all difficult into
OK, high-strength joint cannot just be obtained.If improving interface heat input to obtain enough deformable metal layers, weld interface understand again because
The mutual solubility of storeroom is poor, and temperature is raised and causes brittlement phase to generate, and reduces strength of joint.In addition interfacial thermal stress is added
Greatly, using the material that direct friction weldering mode is larger to weld these different melting points, the second best in quality joint is obtained relatively difficult.
Based on this, applicant considers to be improved existing inertia friction welder, and designs a kind of simple and reasonable, makes
Valency is lower, and welding efficiency is higher, the more preferable foreign material composite welding apparatus of welding quality.
