Accompanying drawing explanation
Fig. 1 is the flow chart of the specific embodiment of the invention.
Detailed description of the invention
Below, by specific embodiment, technical scheme is described in detail.
Embodiment:
With reference to Fig. 1, the present invention proposes melting welding fill process during a kind of aluminium alloy wheel hub is repaired, and comprises the following steps:
S1, select welding equipment: input 220 volts, the output welding equipment of electric current >=200 ampere, output voltage continuously adjust formula
Welding machine, adapt to the high-quality welding operation of different-thickness aluminium；
S2, select protective gas: MIG welding aluminium should select the argon of 100% content, or the mixing of 70% argon and 30% helium
Close gas；
S3, aluminium alloy electrode are matched: when 4043 aluminium alloy welding wires that MIG welding machine uses 0.035 inch diameter make to fill melting welding,
Because the more soft meeting of welding wire causes wire feed relatively difficult, it is the most relatively slow compared with less wire feed that electric current should be adjusted.When using 5336
During aluminium alloy electrode, because the harder thicker 3/64 inch of easy wire feed of this welding wire, electric current should relatively tune up some and otherwise reach not
To due effect；
S4, configure a set of dedicated aluminium alloy welding wire feeder, comprise following article:
(1) nonmetal bushing pipe: can at utmost reduce friction during wire feed；
(2) U-type groove driving rolls: softer aluminium wire fracture or deformation can be avoided, if if using general v-shaped grooved roller,
Easily being scratched by welding wire causes bushing pipe to result in blockage, and causes wire feed fault；
(3) inlet and outlet guide: welding wire scratch can be avoided；
(4) contact head: use the contact head welded at aluminium to have the opening of larger diameter, because when aluminium wire heats up, generation
Expansion ratio steel are many.Therefore, the size of the special contact head of aluminium wire little enough keep electrical contact while, the most enough allow weldering
Silk thermal expansion.
S5, loading welding wire are to welding machine；
S6, the elasticity of welding wire brake is set: the hold welding wire axle safe with hands guarantees that it will not unclamp, once you take apart
Wrapped in Cellophane, just hold that welding wire unclamps with another one, did not loose one's grip before putting it into driving rolls, lacks
The people of few experience would generally not hold with a firm grip unclamped, and causes entire bundle welding wire to start to get loose and scatter, if such thing occurs
, will be unable to remedy, weld job also can be affected by the biggest；
S7, driving rolls elasticity is set: elasticity has only to ensure that welding wire just will not get loose, but can not too tightly,
Otherwise can cause and welding wire is pulled.Want correct setting, first elasticity is transferred to minimum, then loads onto welding wire, allow it pass through
Driving rolls, if except the roller bearing of welding equipment silk is dynamic, and if miscellaneous part all stopped, just explanation is the tightest.During operation
It is careful, because tension can cause the power being added on welding wire too much.It addition, last several circles that welding wire is finished cannot not wanted during wire feed
Nervous；It is usually because welding wire is not easy to get loose too firmly.
It is to be noted that
1) the welding workpiece that is clipped in that, the fixture of welding should be safe does not has the region of japanning and pollution, the position of holding electrode
First to do cleaning, remove all of oils and fats with grease removal solvent, if desired can be by clean rustless steel wire brush by aluminium
Oxide on surface is removed clean.
2), welding when, the straight, at utmost to reduce the wire feed shadow to softer aluminium wire of welding torch cable is kept
Ringing, the bending of welding torch cable line can cause welding wire to be tied a knot, cause wire feed obstacle.
3), all of MIG welding, weld including aluminium, be required for the welding rod of positive pole, and medicated core welding procedure is typical case
Use negative pole welding rod.
1, the selection of power type and polarity such as following table:
The situation such as following table of the electric current allowable corresponding to 2, different electric power polarities and different tungsten electrode diameters:
3, the welding current parameter such as following table of aluminium alloy craft tungsten argon arc welding:
4, welding condition such as following table:
5, the judgement such as following table of rustless steel, aluminium alloy gas shield effect:
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art is in the technical scope that the invention discloses, according to technical scheme and invention thereof
Conceive equivalent or change in addition, all should contain within protection scope of the present invention.
