What is the amperage setting on a tig welder when welding aluminum?
- Best electrodes to use for Aluminum welding is 1.5% lanthanum oxide (gold color code.). 2% zirconia (brown) or 2% thorium oxide (red) can also be used. Note that zirconia-doped electrodes should never be used for DC welding. A lot of welders like to quote offhand the rule 1 amp for every 0.001 inch of thickness. This applies to steel, stainless, and nickel alloys only. Due to the lower melting point, lower specific heat capacity, and higher thermal conductivity of of Al, this rule should NOT be used for Al! I recommend welding a test piece first with the same joint configuration and thickness of the part you intend to weld. Note that fillet welds require more current than butt welds or edge welds. Start out by using 2/3 amp per 0.001 of thickness, in other words, reduce the current of the above rule by about 30-40% . Make 3 test weld, then check to see if there's any visible penetration on the other side. If you don't see any through-pentration at all, increase the current by about 10-20 amps and test again.s
Expansion--Aluminum and Steel?
- Assume linear thermal expansion with constant expansion coefficient. The change of length is given by: ΔL = L₀·α·ΔT (L₀ initial length, α linear thermal expansion coefficient) The overall length of an object as function of temperature is: L= L₀ + ΔL = (1 + α·ΔT) · L₀ Consider the measurement at 21.2°C as reference: The aluminum column changes its length to L= (1 + α_aluminum · ΔT) · L₀ = (1 + 23×10-6 ^C°-1 · (35.4°C - 21.2°C) ) · 17.7m = 17.705m That would be the length measured with a steel tape at reference temperature of 21.2°C. Unfortunately the steel tape expands too. Because the scale increases with the expansion it measures too short. On the expanded tape you read the length L₀ while the actual length is L. Hence the measured length is: L₀ = L / (1 + α_steel · ΔT) = 17.705m / (1 + 11×10-6 ^C°-1 · (35.4°C - 21.2°C) ) = 17.003ms
How do aluminium plates oxidize?

connect copper to aluminum?
- It is safer to replace aluminum with copper. Joints between copper and aluminum tends to oxidize and overheat Electrical fire may happen because of it. In aerial installation, copper is joined to aluminum by means of compression lugs and the lugs screwed together with dow corning compound as anti-oxidant compounds
