Background technique
In the case where Global climate change, energy crisis highlight the multiple pressure with increasing environmental pollution, energy-saving and emission-reduction just become
The only way of Global Auto industrial realization sustainable development.There is correlative study to show that car mass is every and mitigate 10%, oil consumption will
Reduce 6%~8%.So automotive light weight technology is one of the most effective measure for alleviating above-mentioned pressure.Aluminium alloy-high-strength steel Combined Welding
It connects that structural strength is high, corrosion-resistant, light weight, the excellent performance of two kinds of metal materials can be played simultaneously, be that automotive light weight technology is excellent
One of structure first considered.But since the physical properties difference such as aluminum steel fusing point, thermal coefficient, specific heat capacity and thermal expansion coefficient is aobvious
It writes, and solid solubility of the iron in aluminium is extremely low, causes the weldability of aluminum steel dissimilar metal very poor, and contracting is easy to produce in welding point
The defects of hole, crackle and hard crisp intermetallic compound, considerably reduce the mechanical property of connector, limit aluminum steel structure and exist
The application of automotive field.
Magnetic pulse welding is a kind of novel high-energy forming technique, and forming speed is not necessarily to heating, without heat fastly, in forming process
The zone of influence has both high-rate forming and solid diffusivity two-fold advantage, and the weaker base material of the strength of joint of acquisition is high, can solve above-mentioned
Welding is led to the problem of.The type of attachment of magnetic pulse welding has pipe-pipe, pipe-bar and board-to-board etc..Carry out pipe-pipe magnetic pulse welding
When, need to guarantee pipe and pipe there are also collecting coaxial between chinaware three, so that pipe fitting uniform force, guarantees forming quality.But
Whether we are difficult to judge to manage and manage coaxial there are also realizing on earth between collection chinaware in operation.
