Description
Technical field
The present invention relates to welding technology field, in particular to the argon-are welding technology of a kind of articles made of aluminium alloy.
Background technology
Argon tungsten-arc welding (TIG) is, to make as nonconsumable electrode with pure tungsten or activation tungsten (thorium tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten)
With argon as the arc welding method of protective gas.It has, and weldquality is high, welding deformation is little with stress, weldable material is wide
General, operating technology is prone to the feature grasped.
Aluminium alloy owing to having that strong oxidability, bigger thermal conductivity and specific heat capacity, hot cracking tendency be big, welding time easy
Form pore or the feature of burn-through, cause aluminium alloy to be difficult to welding or weld strength not high alumina very strong, at sky with the affinity of oxygen
Easily being combined with oxygen in gas and generate fine and close and solid aluminium sesquioxide thin film, thickness is about 0.1 μm, and fusing point is up to 2050 DEG C,
Considerably beyond aluminum and the fusing point of aluminium alloy, and density is very big, about 1.4 times of aluminum.In welding process, aluminum oxide film meeting
Hinder the good combination between metal, and easily cause slag inclusion.Aluminum alloy thick plate, in welding process, normal produced problem is exactly
There is oxidation, pore, fire check and the problem such as subside in welding.
Summary of the invention
Technique is simple, efficiency to reach to it is an object of the invention to provide the argon-are welding technology of a kind of articles made of aluminium alloy
The purpose high, weldquality is good, solves the welding of existing Welded technique and oxidation, pore, fire check occurs and subside
Problem.
For realizing the object of the invention, the technical scheme of employing is: the argon-are welding technology of a kind of articles made of aluminium alloy, and it is special
Levying and be, described argon-are welding technology step is followed successively by: a) product cleans: first by aluminum and Al alloy parts 6-10% hydrogen
Sodium hydroxide solution is cleaned 30-60 minute at a temperature of 40-60 DEG C, then by aluminum and the Al alloy parts hydrochloric acid of mass ratio 15%
Soak 1～3 minute at 20～50 DEG C and remove aluminum and the oxide-film on Al alloy parts surface and greasy dirt, prevent, during welding, pore occurs
And slag inclusion；
B) product pretreatment: sheet material uses machining weld groove, and angle is 60 °～80 °；
C) preheating: in order to make to reach near seam required temperature, welded articles made of aluminium alloy is preheated, in advance before weldering
Hot temperature is 80-100 DEG C, and heat range is 5 times of articles made of aluminium alloy thickness；
D) welding wire is selected: use ac tungsten inert gases welding during welding, use super-purified aluminium welding wire, the welding current of 220～240A；
E) determine welding condition: according to the specification of articles made of aluminium alloy, determine tungsten electrode diameter, gage of wire, weldering
Connect electric current, argon flow amount, the welding number of plies and groove type；
F) welding: 20% weld articles made of aluminium alloy is set to sheet metal thickness in the front fit-up gap of weldering, and at any time
Check weldquality；
G) postwelding cleaning: after having welded, carries out necessary cleaning to welded articles made of aluminium alloy, repairs weld defect, then
Classification is placed in regulation region.
Further, the weld groove in described step b) is arranged in sheet material upper and lower faces.
Further, the speed of welding of described Aluminum alloy thick plate welding procedure is 60～80 mm/min.
Employing present invention have the advantage that
Aluminum alloy thick plate welding procedure the most of the present invention, simple to operate, under the state of technological parameter stability contorting,
Welding effect is good, does not haves oxidation, pore, fire check and the problem such as subside；
2. there is technique be simple and convenient to operate, be prone to grasp, the feature that low cost, efficiency are high, the articles made of aluminium alloy of welding
Weldquality is good, the most attractive in appearance, is the articles made of aluminium alloy argon tungsten-arc welding process of a kind of excellence.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
The argon-are welding technology of a kind of articles made of aluminium alloy, it is characterised in that the thickness of described articles made of aluminium alloy is 5 millimeters
Above sheet material, described argon-are welding technology step is followed successively by: wherein preferred embodiment is:
A) product cleans: first at a temperature of 450 DEG C, aluminum and Al alloy parts are cleaned 45 points with 8% sodium hydroxide solution
Clock, then aluminum and the Al alloy parts hydrochloric acid of mass ratio 15% are soaked 2 minutes removal aluminum and Al alloy parts surface at 35 DEG C
Oxide-film and greasy dirt, prevent welding time pore and slag inclusion occur；
B) product pretreatment: sheet material uses machining weld groove, and angle is 75 °；During welding, sheet material is heated swollen
Swollen, cause weld groove gap to be reduced, if it is little to weld front fit-up gap Liu get Tai, welding process will cause the groove of two plates
Overlap, increases postwelding plate face unevenness and deflection
C) preheating: in order to make to reach near seam required temperature, welded articles made of aluminium alloy is preheated, in advance before weldering
Hot temperature is 90 DEG C, and heat range is 5 times of articles made of aluminium alloy thickness；
D) welding wire is selected: use ac tungsten inert gases welding during welding, use super-purified aluminium welding wire, the welding current of 220A；
E) determine welding condition: according to the specification of articles made of aluminium alloy, determine tungsten electrode diameter, gage of wire, weldering
Connect electric current, argon flow amount, the welding number of plies and groove type；
F) welding: 20% weld articles made of aluminium alloy is set to sheet metal thickness in the front fit-up gap of weldering, and at any time
Check weldquality；
G) postwelding cleaning: after having welded, carries out necessary cleaning to welded articles made of aluminium alloy, repairs weld defect, then
Classification is placed in regulation region.
Weld groove in described step b) is arranged in sheet material upper and lower faces, the processing of weld groove use special with
