RE: Knee wall - foundation wall 'hinge'. You have an 8' high wall that is continuous and that is much stronger than a wall with a hinge. An 8' high masonry wall is routine irregardless of the amount of unbalanced load.
Flux and Solder. For decades, copper pipe has been one of the most common materials used to distribute water throughout the home. The most common technique used to join sections of copper pipe is called soldering.In the soldering process, heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal.This guide will help you identify the flux and solder appropriate for your project, so you can feel confident youâre getting the job done correctly.n the soldering process, heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal.

  Solder is a fusable metal alloy Solder is a metal alloy used to join metal workpieces and having a melting point less than that of what you're joining. Solder is used â¦ to connect electrical components together so they'll work in a circuit.It is also used for joining plumbing fixtures and pipes and fittings.tep 2) When the soldering iron is hot enough, tin the tip of it with solder or t â¦ inning compund. Step 3) Heat the parts that are going to be joined. DO NOT MOVE THE SOLDERING IRON. Step 4) Slowly push the solder into the heated area.
