What Parameters can Limit Atmosphere Brazing with Induction?

Brazing within an atmosphere is done by using a flux. This flux is not wished for in some applications the product is used for due to its corrosive nature. In addition brazing in atmosphere will result in more cleaning requirements after the joint was created

Why is Atmosphere Brazing Beneficial in Cold Atmospheres?

Cold atmospheric brazing is typically considered low temperature joining of two metals at temperatures upto 500 degrees Celsius. This results in faster heat cycles, less power requirement, quicker cooling cycles and less distortion due to the lower temperature input.

What are the Benefits of Atmosphere Brazing?

Due to the fact that brazing in an atmosphere is less complex than in an inert atmosphere the production rate is greatly increased. In addition less complex investment is required as it does not require specialized equipment to create an inert atmosphere or vacuum. Brazing in atmosphere is more versatile as setup changes are easily conducted in order to produce different parts

Controlled Atmosphere Brazing with Induction

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.

Benefits of Induction Brazing in a Controlled Atmosphere

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.
