Everything You Need to Know About Therm-x’s Furnace Brazing and Metal Joining Capabilities

Over the years, there has been a rapid advancement in material and process engineering. These advancements have been utilized efficiently by manufacturers of medical instruments and process equipment to create strong and durable parts. Nowadays, dissimilar materials are fused to make heaters, sensors, medical and microwave equipment. Working with dissimilar materials is not easy and comes with its own set of challenges. Their fusion is performed in a temperature controlled environment by employing various processes. Brazing is one such process where fillers such as alloys of nickel, silver, copper, and other metals are used to join two dissimilar materials. These fillers are melted and then added to a joint. Once cooled, they solidify and bond the two distinct materials.

Like brazing, welding is also one of the common techniques used to join metals for creating sensors, thermocouple wires, cables, and so on. TIG and laser welding are two important types of welding employed by manufacturers of aforementioned components. Nowadays, welding and brazing are performed using advanced temperature controlled equipment such as brazing furnaces and welding machines. Owing to their increasing industrial use, today, you can find them in different configurations and designs made by various manufacturers. Among these manufacturers, Therm-x stands tall by offering the most advanced hydrogen and vacuum brazing furnaces as well as thermocouple welders. This post take a look at how these temperature-controlled devices are adding value to sensor and thermocouple manufacturing.

A Few Beneficial Features of Therm-x’s Hydrogen and Vacuum Brazing Furnaces

Be it hydrogen or vacuum brazing furnaces, both are made of different chambers that have different atmospheres. The fillers are melted and allowed to cool and solidify in one of the chambers within the furnace. Using Therm-x’s furnaces for brazing offer distinct advantages:

  • You can join any number of metal parts within a short span of time. This can be done on the same assembly with continuous brazing.
  • The fixturing and finishing is minimal and done with the help of gravity. This reduces process complications.
  • Most hydrogen brazing furnaces have a quick and controlled cooling process as much as they heat up.
  • Vacuum furnaces are easy to use and the vacuum levels can be adjusted with the help of a cryo pump.
  • Vacuum furnaces are widely used for active metal brazing, clean vacuum firing, and controlled vacuum annealing.
  • Vacuum furnaces may also be used for processes aside from brazing, wherein metals such as titanium and niobium are involved.
  • They are good for production of small parts as well as prototyping.
  • Both furnaces are equipped with integrated process control systems. These systems help control temperature effectively. The hydrogen furnace can be easily ramped to a desired temperature in few minutes.
  • These brazing furnaces are made of robust base materials such as brass, copper, stainless steel, and carbon steel.
  • These are cost effective in the long run, low on maintenance, and help improve the quality and productivity of the final product.
  • Both furnaces are self-cleaning types, and easy to maintain in a long run.

Types of Thermocouple Welders Provided by Therm-x

Thermocouples are widely used in temperature measurement, and thermocouple junctions need to be welded. They are welded using TIG or laser welders. Here is the difference between these two welding techniques, and the benefits of using Therm-x thermocouple welders.

  • Laser Welders:The fusion of parts in this technique is done through an intense and concentrated laser beam. The heat melts the parts together to fuse them. Laser technique leads to just enough amount of heat being produced. The Therm-x laser welder helps fuse work pieces at the surface. Also, they can be used in the traditional welding process for soldering.
  • TIG Welder:TIG stands for tungsten-inert gas. In this method, an electric arc is used. It generates heat which fuses the required parts. This technique generates a lot of heat and it is not spread uniformly. Usually, the heat is more in the center than near the edges. The Therm-x TIG welder operates in conjunction with a pressure-reducing valve and a bottle of argon gas. Current flows through the two thermocouple wires, which heats them up to their melting point. Once the power is withdrawn, the wires cool to form a welded thermocouple.

In both these techniques, the amount of heat produced and the uniformity with which it spreads throughout the surface is different, owing to their different temperature requirements. As known, temperature sensors are designed to provide accurate temperature measurements, so their manufacturing needs precision. This is where Therm-x brazing furnaces and welders can help.
