Vacuum induction brazing furnace process method

Vacuum induction brazing furnace process method

Vacuum induction brazing furnace process methods is more, mainly is divided according to the use of equipment and working principle. According to the heat source such as have infrared, electron beam, laser, plasma, glow discharge brazing, etc.; According to the working process of the points have contact reaction brazing and diffusion brazing, etc. Contact reaction brazing is the use of filler metals andparent metal reaction liquid filling joint gap. Diffusion brazing is to increase the thermal diffusion time, make the weld and parent metal full homogenization, to get the same as the parent metal properties of joints. Vacuum induction brazing furnace process method
Soldering iron soldering for small soft soldering of simple or very thin parts.
Wave soldering is used for large quantities of printed circuit boards and electronic components assembly welding. Welds, around 250 ℃ in the molten solder under the pressure of pump through the narrow seam formation wave, workpiece after wave for welding. This method is of high productivity, can realize automatic production on line.
Flame brazing with combustible gases mixed with oxygen or air combustion flame as a heat source in welding. Flame brazing equipment is simple, easy to operate, according to workpiece shape available flame heating welding at the same time. This method is suitable for the bicycle frame, aluminum water spout and other medium and small welding.
Dip soldering part or the whole workpiece in covering flux of solder bath or only the molten salt salt bath heat welding. This method is heated evenly and quickly, more accurate temperature control, suitable for mass production and welding of large components. Salt bath salt in more composed of soldering flux. After welding workpieces are often left plenty of soldering flux, cleaning work.
Induction brazing with high frequency, intermediate frequency or power frequency inductive current welding method as a heat source. High-frequency heating is suitable for welding thin wall pipe fittings. Coaxial cable and jewels can be away from the power of the induction coil, the field brazing, especially suitable for some large components, such as the rockets need to remove the pipe joint welded on.
Furnace brazing will be assembled in solder artifacts in heating furnace of welding, often need to add solder, also can use a reducing gas or inert gas protection, heat evenly. Mass production can be adopted when the continuous furnace.
Vacuum induction brazing furnace workpiece heating in vacuum chamber, is mainly used to request the product with high quality and ease of oxidation material welding.
