Furnace brazing is a semi-automated process used to join metal components with a dissimilar, lower melting filler metal. It allows designs of one or multi-joint assemblies to be joined by a reproducible metallurgical bond. One of the most common forms of furnace brazing is accomplished in a vacuum furnace.

There are several processes that can be used to braze stainless steels-furnace, induction, resistance, or torch. Today, our focus is on flux brazing with a torch. When mechanized, torch brazing offers production-line efficiency, can be applied to short- and long production runs, and requires a relatively low investment in equipment and fixtures. There are six fundamentals of brazing that every brazer should follow to ensure consistent and repeatable joint quality, strength, hermeticity, and reliability. the brazing temperature needs to be as low as possible. the heat in-put to the work balanced so that no portion of the joint experiences an excessive temperature. Brazing under reducing atmospheres. The reducing atmosphere furnace brazing of stainless steel has seen rapid, and ongoing expansion since the mid-1990's. The types of brazing processes include torch brazing, furnace brazing in different atmospheres (dissociated ammonia, dry hydrogen, and vacuum atmosphere), dip brazing in salt bath, and high-energy-beam brazing. A complete list of the typical compositions and properties of standard brazing filler metals for brazing stainless steel is also provided.

Furnace Brazing Stainless Steel (SST) in a hydrogen atmosphere and welding are common metal joining techniques we use every day at Altair Technologies. Unlike mild steel, SST is a low vapor pressure material and is frequently used in very high vacuum applications. 1. Gas carburising and carbonitriding 2. Neutral hardening and annealing 3.

Vacuum & Furnace Brazing Services Altair Products Overview A global leader in LINACs, RF windows, electron guns, ion-pumps, and target assemblies. LINACs & Peripherals Overview Linear Accelerators The dew point is used to determine the amount of water vapor in the system at given conditions. The dew point is the temperature at which an amount of water vapor in the system will saturate the atmosphere. The typical dew point required for brazing stainless steel joints in 100% Hydrogen is -50º F.

Furnace brazing provides the highest quality joints and is the only technique well adapted to complex assemblies, ceramic-to-metal bonding, large/massive parts, or highly reactive materials because assemblies are heated uniformly and multiple joints are brazed simultaneously. Through the process of vacuum furnace brazing or vacuum diffusion bonding, we can join the alloys used in your applications. It's a low-distortion method that results in ultra-strong parts. Both a clean assembly room and a high-purity brazing furnace with excellent temperature control are crucial to the process. We've got that covered.
Furnace brazing can also be used to join metals that are difficult to weld, such as aluminum, copper, and stainless steel. Inert Atmosphere. Furnace brazing is typically performed in an inert atmosphere, such as nitrogen or argon. This prevents the formation of oxides on the surface of the metal, which can weaken the joint. Furnace brazing typically refers to the vacuum furnace batch-type brazing process. This involves a large "oven" where entire batches of parts are loaded into the furnace at one time. The furnace door is then closed, and the furnace is evacuated of all air then heated to the desired brazing temperature.

Description. Furnace brazing is a semi. What Is Brazing? Brazing joins metals by flowing a thin capillary thickness layer of non-ferrous filler metal into the space between them. Bonding results from the intimate contact produced by the dissolution of a small amount of base metal into the molten filler metal, without fusion of the base metal.
