Would it be ok to solder,brass or hard metal, to make table legs? Or Would the joint not be able to hold much weight?

What is "hard metal"? A properly designed solder joint will be very strong. I have such a solder joint hold while the attached steel failed.– blacksmith37Commented Oct 12, 2017 at 16:36

A good quality "turbo torch" or an oxy-acetylene torch is needed for brazing. Also, you will need the correct type of brazing rod matched for the material you are brazing. A good brazed joint will take practice. It is not as easy as soldering
Solder? Very unlikely. The bond is designed for electrical conductivity not physical strength (or, in the plumbing case, to achieve a certain strength via capillary action in a very small space). But brazing, that could work, if you have the capability to heat the metal, such as a forge. And welding of course is as strong as the metal you are welding itself.

Oh i see! Thank you. Do you know if a propane torch can reach the temps to blaze harder metals such as steel? Commented Oct 12, 2017 at 6:43

Propane torch works inside of a forge (e.g. built from bricks), usually used together with forced air for higher efficiency. For hard-brazing, you need at least oxy-propane or oxy-acetylene torch and even oxy-propane does not work for each situation.– MatejCommented Oct 12, 2017 at 10:39
If you are building workbench table from construction steel, e.g. square tubing, stick, MIG, or TIG welding is the way to go.
