Track union! A doubt...

Hi all!
I saw in websites from US a kind of welding machine. I want know if it uses fire or high temperature? The machine purpose is to join two metalic tracks in the model.
Here in Brazil we do it with a metalic acessory like in the link http://loja.tray.com.br/loja/produto-23360-2106-Talas_de_juncao_100_pcs_40000 , but this is not good in curved tracks made without the apropriated model kits because the track stay out of alignment. Do you use it in your models?

Yes we use them they are called rail joiners. Some people solder them with a soldering iron or soldering gun. But most slide them on and leave them. I myself will solder curved track and short pieces of straight track but on the longer staights I leave unsoldered and leave a small gap for expansion. I build mostly modules that are exposed to weather extremes and stored in the cellar when not used.

Soldering is like welding but not as hot.

Thanks Pete! I understand it.

I’m get starting my first layout with my dad and I have many doubts, thanks for your atention. My dad has a more time in railroad model but this is his second layout. With the progress of the layout I will post photos.

Keep at it. You will find all the help and advise you will need here. Otherwise someone will point you in the right direction. Have you purchased any books or magazines to help you?

Hi Mike!
Thank you for your help words!
Unfortunately here in Brazil the literature about railroad model is very poor. My major knowledge font is this forum, some websites and empiricism as attempt and mistake.
