Robotic aluminum welding characteristics of aluminum and aluminum
alloy
1. Aluminum is easily oxidized in air and during welding, and the
formed alumina (Al2O3) has a high melting point and is very stable
and difficult to remove. It hinders the melting and fusion of the
base material, and the ratio of the oxide film is large, and it is
difficult to float out of the surface, and it is easy to form
defects such as slag inclusion, unmelted, and insufficient
penetration. The surface oxide film of aluminum and the adsorption
of a large amount of moisture easily cause pores in the weld.
Chemical or mechanical methods should be used for strict surface
cleaning before welding to remove oxide film on the surface.
Strengthen protection during the welding process to prevent
oxidation. In the case of tungsten argon arc welding, an
alternating current power source is used to remove the oxide film
by "cathode cleaning". For gas welding, a flux that removes the
oxide film is used. In the thick plate welding, the welding heat
can be increased, for example, the arc heat is large, the helium
gas or the argon - helium mixed gas protection is used, or the
large - scale gas metal arc welding is used, and in the case of the
DC positive connection, the "cathode" is not required clean up.
2. The thermal conductivity and specific heat capacity of aluminum
and aluminum alloy are more than twice that of carbon steel and low
alloy steel. The thermal conductivity of aluminum is ten times that
of austenitic stainless steel. During the welding process, a large
amount of heat can be quickly transferred to the interior of the
base metal. When welding aluminum and aluminum alloys, energy is
consumed in addition to the molten metal bath, and more heat is
consumed in other parts of the metal. The consumption of useless
energy is more significant than that of steel. In order to obtain
high - quality welded joints, energy sources with concentrated
energy and high power should be used as much as possible, and
sometimes preheating and other technological measures can be used.
3. The coefficient of linear expansion of aluminum and aluminum
alloy is about twice that of carbon steel and low alloy steel. When
the aluminum solidifies, the volume shrinkage rate is large, and
the deformation and stress of the weldment are large. Therefore,
measures for preventing welding deformation are required. When the
aluminum welding bath is solidified, shrinkage, hot cracking and
high internal stress are easily generated. Measures to adjust the
composition of the wire and the welding process can be used in
production to prevent the occurrence of hot cracks. In the case
where corrosion resistance is allowed, an aluminum alloy other than
the aluminum - magnesium alloy may be welded using an aluminum -
silicon alloy wire. When aluminum - containing silicon alloy
contains 0.5% silicon, the thermal cracking tendency is larger. As
the silicon content increases, the alloy crystallization
temperature range becomes smaller, the fluidity is significantly
improved, the shrinkage rate is decreased, and the thermal cracking
tendency is also reduced accordingly. According to production
experience, when silicon containing 5% to 6%, thermal cracking does
not occur, so the use of SAlSi strips (silicon content 4.5% to 6%)
will have better crack resistance.
4. Aluminum has a strong ability to reflect light and heat. When solid or liquid is turned, there is no obvious color change, and it is difficult to judge during welding operation. The high - temperature aluminum has a very low strength and is difficult to support the molten pool and is easy to weld.
5. Aluminum and aluminum alloys dissolve a large amount of hydrogen in a liquid state, and the solid state hardly dissolves hydrogen. In the process of solidification and rapid cooling of the weld pool, hydrogen does not have time to overflow, and hydrogen holes are easily formed. The moisture in the arc column atmosphere, the welding material and the moisture adsorbed by the oxide film on the surface of the base metal are all important sources of hydrogen in the weld. Therefore, the source of hydrogen should be strictly controlled to prevent the formation of pores.
6. The alloying elements are easily evaporated and burnt, which deteriorates the weld performance.
7. When the base metal of the base material is subjected to
deformation strengthening or solid solution aging strengthening,
the welding heat may lower the strength of the heat affected zone.
8. Aluminum is a face - centered cubic lattice with no isomers.
There is no phase change during heating and cooling. The weld
grains are easily coarsened and cannot be refined by phase
transformation.
