Description
Technical field
This utility model relates to welding and the connection area of metal material, and particularly a kind of pulse current combines welder with laser.
Background technology
Laser welding is the one of high energy beam welding, especially exists
20
Century
70
After making a breakthrough at the beginning of age, laser welding has started large-scale application.At civil area, laser welding extensively applies its field such as automobile, high ferro；In aircraft industry and other many application, laser welding is capable of the connection of a lot of types of material, and laser welding is generally of the superiority that other welding process many are incomparable, especially laser welding can connect aviation and the sheet alloy material comparing difficult weldering in auto industry, such as aluminium alloy etc., and the deformation of component is little, joint quality is high.Laser machining another attractive application aspect is to make use of laser to be capable of the little scope heat characteristic in local, produces the highest mean temperature in region that can be the least, and the region beyond joint is then substantially unaffected.But, similar, after laser carries out local welding, due to high cooldown rate with alternate manner welding so that welding melting range creates residual stress, thus have impact on the overall performance of structural material.At present, the method eliminating welding residual stress is all that the method by postwelding secondary heat treatment is carried out.
Summary of the invention
The purpose of this utility model is, it is provided that a kind of pulse current combines welder with laser, it is achieved that while laser welding, eliminates welding stress, eliminates the process of later-stage secondary heat treatment, improve production efficiency, reduces the energy and human cost.
The technical solution of the utility model: a kind of pulse current combines welder with laser, including welding bench, welding bench is provided with insulating pad and hydraulic means, and hydraulic means is provided with conductive electrode, and conductive electrode is connected with impulse current generator by wire；Impulse current generator is connected with controller by data wire；Having laser instrument above welding bench, laser instrument is connected with the laser generator on controller by optical fiber.
Aforesaid pulse current is combined in welder with laser, and insulating pad is provided with part to be welded, makes part to be welded contact with conductive electrode by hydraulic means, and interface pressure scope exists
1-12MPa
Between.
Aforesaid pulse current combines welder with laser, and the output pulse current frequency of described impulse current generator exists
100-500Hz
Between.
Compared with existing apparatus, this utility model is when welding metal material, in the later stage of welding, applies pulse current, by the resistance heat of pulse current, eliminates localized heat stress；The introducing of pulse current simultaneously so that material is not only by resistance heat, moreover it is possible to drive atomic migration and solute redistribution, crystal grain thinning by electric current, improve intensity and the toughness of material.Both improve the preparation effect of material, eliminate again the complicated technology of secondary heat treatment, energy-conservation human and material resources and financial resources.
