Guess your wrong they do use it to weld beams most common use is welding train tracks and subway lines.

Just to remind you folks of what happened that day, some of those 'secondary explosions' that occurred after the impact were actually the sound of bodies in alot of cases hitting the ground or the glass above. It was real. I find it funny how you believe people that heard some thing in some cases but not if they SAW planes hit the buildings...real planes...LOL..what kind of logic is that?
Golden, also to clarify, the WTC was not designed to withstand multiple hits of a airliner but to withstand the impact of one that was of course, in the fog, and if there was a collision the structure would stand long enough to allow evacuation. I know who you are quoting and it is incorrect.

I just watched the video. i wonder how many of those reporters either didn't get a bonus that year, or were fired??
Thermite welding (TW) is a welding process which produces coalescence of metals by heating them with superheated liquid metal from a chemical reaction between a metal oxide and aluminum with or without the application of pressure.
Filler metal is obtained from an exothermic reaction between iron oxide and aluminum. The temperature resulting from this reaction is approximately 2500°C.

When the article describes THERMATE compounds being discovered, which burn at significantly higher temperatures (3000C) and are well noted for their destructive uses.
Which again further limits the usefulness THERMATE would have had in high-rise construction and further narrows the likelihood traces of THERMATE would be found in the rubble.
The main chemical reaction in thermate is the same as in thermite: an aluminothermic reaction between powdered aluminum and a metal oxide. In addition to thermite, thermate also contains sulfur and sometimes barium nitrate, both of which increase its thermal effect, create flame in burning, and significantly reduce the ignition temperature. Various mixtures of these compounds can be called thermate, but, to avoid confusion with Thermate-TH3, one can refer to them as thermite variants or analogs. The composition by weight of Thermate-TH3 (in military use) is 68.7% thermite, 29.0% barium nitrate, 2.0% sulfur and 0.3% binder (such as PBAN). As both thermite and thermate are notoriously difficult to ignite, initiating the reaction normally requires trained human supervision and sometimes persistent effort.
Barium Nitrate is an oxidising metallic element similar to iron. You have to remember the composition of "Thermate" is not uniform, just like other destructive compounds like C-4/Semtex/RDX (which are all plastic explosives).
Hence different corporations who produce Thermate will use different substitutes, instead of Barium Nitrate, they might have substituted with another oxidising metal like Iron.
The results are still the same. It still produces intense temperatures capable of cutting through steel columns.
The lack of sulphur in the analysis can probably best be explained by the fact that it is a multivalent NON-METAL and most of it burns up in the initial ignition reaction.
It wouldn't surprise me any traces of sulphur were not found, elemental sulphur is simply soft, malleable rocks that would probably all burn up in intense heat, nowhere near as durable or persistent as metals such as iron or barium.

Read my previous post. Thermite is simply too hot to be used to weld common construction materials like steel, iron and corrugated metals because it would melt them instantly.
It simply burns at too high a temperature to be a useful welding medium. It might have limited use in welding heat-resistant compounds or fire-retardant materials used in skyscrapers but not ordinary steel and things like that.
Thermite is best suited to pyrotechnics and demolition.
Seems pretty convenient that the 2 distinctive ingredients
I have seen Thermite used many times for welding steel rails for railway tracks.
