Thermite railroad welding

[ahomick]

booo... buy a flash butt welder!!!!!! This is OBSOLETE.

[coldblue9mm]

@ahomick You're talking out your ass. This is very much in use today on American railroads. This is called "Field Welding" and is done by local welders on districts everywhere. Flash butt welding is great but is used more in a production type setting, ie large rail gangs, projects and so on. So get back under your bridge you troll. You know nothing. And NO, this isn't how CWR is made, it's how CWR stays CWR when you have to cut in a replacement rail due to defects.

@coldblue9mm Used in American sckyscrapers as well - A endorsed by GW Bush.

[CCSinventions]

@ahomick i love welding but if i get the chance to use thermite i will

[notfarfromhome]

I wonder if this is how CWR is made?

at first i thought the title said wedding

[0pteryx]

@toastfan902 Hmm, "Thermite Railroad Wedding" Now that sounds like something you could come across in redneck land.

rofl nice short sleeves

THERMITE 4 LIFE, i am a thermiter and its awsome. this is the old school way

[loey523]

now touch it

[UFOSPACE1999]

I think they also pop corn in it.

mermaid killer?

you asshole!

LAs medidas de seguridad para hacer una Soldadura Aluminotermica son inexistentes en este video, veo que en España lo hacemos muy bien,

impresionante

[GrimJesterr]

@llocesar La gente en Suiza y en los Países Bajos es INTELLIGENTE, y no se lesiona. Los operarios en España son idiotas, por eso necesitan medidas de securidad.

[llocesar]

@GrimJesterr los Suizos seguro que son mas inteligentes, no que los españoles si no que tú, que demuestras tu falta de argumentos con el insulto facil, Mirate el video y no te hagas pajas mentales con los nacionalismos.

[MysteryManoLove]

Smart, never thought of that

[deltaalpha21074]

Hott slag---I love to light thermite up when it's freezing cold like 25 degrees--you can feel the heat 20 feet away it wild!

[C20rules]

Nice!

[soundseeker63]

All that hot metal and flames spraying about and no protective jacket!? are they mad?

[dasgemuse]

no. they just know what there doing

[chriswhiteisawanker]

@soundseeker63 So now england is full with health and safety we have to force the netherlands to have it too.

People in Holland don't sue everytime anything ever happens so they dont need it...

[sdrfgvrfgvsfravgdsvS]

wtf

[Barnekkid]

How come the joints aren't staggered?

[FL4ME5]

the standard is to have all weld opposite each other. if this is not achieved the rails are under different stress patterns and they can snap

[thebignsexy]

i thought fra says otherwise, stagger my friend, stagger

[FL4ME5]

my comment is from uk standards (network rail)

[garywilton1980]

what country is this in??? nice overalls......

[sloupyhangon]

do they use thermite instead of a stick welder because it penetrates deeper and fuses the tracks together better?

[sykop8ntballer]

I'd assume that they use thermite because it's:

-Quicker

-Cheaper

-Easier

I don't know much about thermite welding, but I couldn't immagine that you'd need the same ammount of skill involved with structural steel stick welding. Also, if I understand, the thermite just flows as a big blob of molten steel in a space between the tracks, so I don't think pen's a big issue. But you can get some real deep pen with a stick welder. Deffinatley not as quick though.

[nolanofeast]

theremite burns at 2200 degrees celcius, so yeah it burns RELLE hot and get the job done quickly with quality

[farqtoo98]

the heat is probably how they get the perfect joins?

[nolanofeast]

pretty much

[bozzza69]

no way stick wud get alot more peno but it wud require a skilled welder because that is crack sensitive steel and also alot of runs which = alot of time and money

[andrewthomasTAS]

isnt thermite just aluminum and iron oxide

[HumanStrategy]

yeah

[AlvinAZ]

There's a thin steel disk at the bottom of the crucible that burns through when the mixture is ready. It's automatic by design. :) There's a sandstone looking "ass hole" (as the welders called it;) with a 1/4" hole for the molten steel to pour through. It gets replaced every time.

[billthewelder1971]

wouldnt the thermite burn through? How do you guys do that?

[Crazyconsultant]

The crucible has a ceramic liner in it to stop it....it still gets fuckin hot though!
