Copper tube brazing problem
Release time:
2024-08-09
Summary:
Main factors affecting the brazing process
(1) the influence of the interaction between the solder and the base metal.
(2) the effect of brazing heating temperature.
(3) The effect of the gap size between the two brazed parts: the capillary height and the gap width are inversely proportional, the liquid brazing material dissolves the base material, deviates from the eutectic point, and makes the fluidity worse.
(4) Influence of liquid brazing fluidity.
(5) Effect of oxides on the surface of the metal to be brazed.
(6) the influence of flux.
(7) Effect of surface active substances.
Problems that easily occur when brazing heat exchangers
(1) The solder is not filled in the weld gap
(2) the loss of solder in the lumen of the formation of solder tumor
(3) Virtual welding (incomplete welding)
(4) Porosity in brazing seam
(5) Dissolution and dissolution
(6) Over-burning and burn-through of base metal copper tube
