The CMT welding welding-guns 5 and the angle of forming face are 70 °~90 °；The industrial computer complete whole formation system control and
Data analysis pretreatment work.
Above in the installation of laser 6, because aluminium alloy is high to the reflectivity of laser, when laser head is perpendicular to work
When part surface works, the laser light focus lamp that is reflected back, is easily burned out optical fiber of making a false countercharge, therefore to reduce reflected light to swashing
The infringement of light device and outer path optics element, require that laser head takes non-perpendicular mode to enter with forming face in installation process
Row installation.Simultaneously to reduce influence of the forming path to forming effect as far as possible, CMT welding welding-guns 5 have a clamp with forming face
Angle.
Control and the data analysis pretreatment work of whole formation system are completed by industrial computer.Starting to shape it
Before, three-dimensional CAD model is first imported into progress slicing treatment in industrial computer and obtains shaping track accordingly, and generates corresponding fortune
Dynamic control routine is used for controlling motion to be formed.And realized to laser start-stop and power, sent by industrial computer
The integrated control of silk speed, arc current, protection air-flow amount and temperature survey.
During increasing material manufacturing, the technological parameter for influenceing laser-CMT welding aluminum alloy increasing material manufacturing methods mainly wraps
Include：In the power of laser 6, speed of welding, welding current, focal position of laser, chevilled silk spacing d, placement direction and induction coil

Corresponding aluminium alloy shaping silk material is chosen according to the material requirements of wanted forming said alloy component, silk material can be selected
The aluminium alloy silk material of the existing trade mark, homemade silk material can also be used as needed.After silk material is chosen, selection is corresponding
Material type and the size requirement of substrate.The Clamp for welding method that either bolt is fixed is used to cause forming board 2 and shaping
Formed and be reliably connected between platform 1.Required in terms of the size of forming board 2, Forming Workpiece is fully located at substrate fixing point institute
Type into closed surface inside, while require that the thickness of substrate is 20~100mm, so it is possible to prevente effectively from due to shaping
The thermal deformation of forming board is to the adverse effect of forming accuracy caused by heat input in journey is uneven.
Three-dimensional CAD model is imported into progress slicing treatment in industrial computer to obtain shaping track accordingly, and generated corresponding
Motion control code control motion be formed.Needed first before the aluminium alloy element required for formal shaping
5~15 layers of bottoming is carried out, can just start the main body of forming said alloy component after the bottoming of component is completed.This is mainly
Because in the shaping stage temperature field of bottom also in unsure state, it is to differ to shape the radiating condition between each layer
The inconsistent of forming property can be caused so that the quality of formed parts is had a greatly reduced quality, in addition, baseplate material and shaping in selection
Aluminum alloy materials it is inconsistent in the case of, the dilution that there is also material is asked questions, therefore is needed before formed parts main body
Carry out 5~15 layers of bottoming shaping.
In terms of forming parameters, it is that below 1.5kW is adjustable to choose the power of laser 6, and laser 6 can select CO2
Laser/optical fiber laser either solid-state laser, working method can be that continuously-running duty can also be pulsed operation

Section first carries out first of deposition, remains laser-electric arc line with shaping cutting at the saltation point of track in deposition process
Line is conllinear, and monitors the situation in temperature field in forming process in real time by thermal camera in forming process.
Machine suspends after first of deposition is completed, and the temperature information collected in real time according to thermal camera, waits
When sedimentary temperature is down to below assigned temperature, printhead is rotated horizontally to last layer and shapes laser-electric arc at end point
The opposite direction in line direction is ready for down shaping together.In the case where carrying out single track deposition, carry out it is lower together into
When shape, the position of composite heat power supply 5,6 and induction coil 3 will first lift certain height relative to forming board 2, lifting
Highly it is 0.5mm~1.5mm, then starts next layer of deposition again.If the method being molded using multiple tracks, compound thermal
Source 5,6 and the position of induction coil 3 to translating a certain distance perpendicular to shaping direction, the distance of translation for 0.5mm~
3mm, the shaping of adjacent passage is then carried out again, after the completion of one layer of All Paths scan, composite heat power supply 5,6 and induction coil 3
Position lifting 0.5mm~1.5mm height, then carry out next layer of shaping.Whole forming process constantly repeats aforementioned process
Until forming process terminates.
Shaping terminate after, treat that whole formed parts are completely cooled down to after room temperature, by 2 related workpiece of forming board from into
Remove on shape platform 1, after necessary heat treatment is carried out, the aluminium alloy element of shaping is cut above forming board, it
The necessary precision for subtracting material processing and improving Forming Workpiece is carried out afterwards.
In summary, when laser and electric arc are welded collectively as thermal source, welding process can be provided simultaneously with swashing
The characteristics of in light and electric arc welding process, made up using the advantages of two kinds of welding manners in independent thermal source forming process not
Foot, produce " cooperative effect ".The mode of this composite welding is applied during increasing material manufacturing, can equally be played laser
The effect that the advantages of mode of the advantages of increasing material mode and electric arc increasing material manufacturing is combined.
