Controlled Induction Atmosphere Brazing
Induction brazing in controlled atmospheres under normal or close-to-normal atmospheric pressure is known as atmospheric brazing, allowing for improved control over the process.
How Induction Atmospheric Brazing Works
Induction brazing in controlled atmospheres under normal or close-to-normal atmospheric pressure, is known as atmospheric brazing, allowing for improved control over the process.
Induction atmospheric brazing in Controlled Atmosphere Benefits
Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals

Braze a thin walled tube to a steel cap in a hydrogen atmosphere
A single turn helical coil is used to heat the quartz tube and the tube assembly. The tube assembly is held in place inside the quartz tube by a copper fixture and hydrogen is fed into the quartz tube...
Annealing stainless steel caps for a dental application
Our client had a requirement to anneal large quantities of work-hardened stainless steel crowns. Induction was suggested for its precise, controllable heating. Since oxidation is unacceptable in the finished dental product, induction heating is the appropriate choice for heating in an inert atmosphere.
Crucible Melting a variety of materials in a nitrogen atmosphere
The crucible is heated using an induction coil with a four turn pancake at the base that extends upward into a three turn helical coil.
Annealing steel tubes in an inert atmosphere
Induction annealing heats steel tubes to 2000 ºF (1093 ºC) in an inert atmosphere for very small areas within precise production tolerances. A two-turn concentrator coil is used to heat the stainless steel tube. The annealing process takes place in an inert atmosphere to prevent oxidation.
Brazing Hydraulic Hose Assemblies
To heat a steel hydraulic hose fitting in an inert atmosphere to 2200°F within 7 seconds for brazing without any carbon buildup.
Brazing Copper Tube Assemblies
To heat a copper tube assembly in an inert atmosphere to 1450°F within 45 seconds for brazing without flux or acid wash clean-up.
Braze Copper Tube to Brass Fitting
To use induction heating to braze a copper tube to a brass fitting using a preform braze wire.
