WebNov 17, 2024 · Capillary action is the result of molecular surface tension, where the liquid is drawn up through a narrow space. This is what occurs with the molten filler metal and the hot pipes being brazed—the surface tension and molecular adhesion between the liquid filer and the pipes draws the liquid metal into the joint. Brazing Temperature Control WebOct 5, 2009 · Remember, capillary action was broken at that point, and brazing with gaps as large as that can be very risky, since part of the joint being brazed might have gap-clearances even larger than that, in which case the joint will not be able to braze completely, and scrap or rework may result!

WebBrazed joints, with capillary fittings, are used where greater joint strength is required or where service temperatures are as high as 350°F. Brazing is preferred, and often required, for joints in air-conditioning and refrigeration piping. Electric resistance joining is a flameless way to make soldered joints, although heat is still generated.
