Soldering
Information
You can solder - * Steel
- * Stainless Steel
- * Copper
- * Brass
- * even Aluminium (but the solider is expensive and hard to come by)
If you cover or fill the inside of any solder item it will make any repair that much more difficult.
There are various types of solder, some cheap, some with better vibration strength. Best to go cheap as that will be more common in places where you may need a repair.
Failures on most things occur near the ends - you can strengthen the ends by putting another short length of tube side the first. You could solder it there too (to further increase the strength) provided you are not going to brazed or weld it.
Copper is heavier and more expensive than steel. For those reasons most people use steel. Copper can be tempered using heat (just like steel) to make it 'hard' (or stiff in non techinical terms).
The plumbing joints that include the solider will be as strong as those without, they are just more expensive (but reduces the labor cost so cheaper for people paying for labor, and you probable cannot get thoes without solider any maore anyway).
