Inconel Stick Welding – An Overview

Inconel Stick Welding

Inconel stick welding is a type of welding process used to join two separate pieces of metal together. It requires specialized equipment, and operators need to be properly trained in order to get the job done right. This is because the extreme temperatures and high levels of heat produced by the weld can easily damage materials and make them harder to work with. As a result, it’s important for those who are welding with Inconel to have an understanding of the process and how it works.

What is Inconel?

Inconel is a type of material made up of nickel-chromium alloy, which allows it to resist corrosion, oxidation, and high heat better than other metals. It’s often used in applications that require superior strength at higher temperatures; as such, it’s often found in aircraft engines, industrial furnaces, chemical processing plants, and power plants. Because of its unique properties, it can be difficult to weld with traditional methods like arc or MIG welding. This is why stick welding is one of the most popular processes for working with Inconel.

Process Overview

Inconel stick welding involves attaching a consumable tungsten electrode (or “stick”) to an appropriate power source and then heating up the metal until it reaches an optimal temperature for joining. Once the metal has reached its ideal temperature (which varies depending on what kind of electrodes are being used), an arc will form between the electrode and the base metal as an electrical current passes through them both. This arc will create intense heat that binds the two pieces together into one solid structure.

The process requires skillful operators who know exactly how much amperage should be used in order to achieve a strong bond without damaging either piece of metal involved in the weld. The operator must also choose their electrodes wisely – some electrodes are specifically designed for use on certain types of materials and/or metals, while others may not be suitable for all materials/metals being joined together. Lastly, because this type of welding produces hazardous fumes that can cause serious health damage if inhaled or ingested, safety gear must always be worn while operating any kind of welding machine or device.

  • Inconel is a nickel-chromium alloy that is used for a variety of applications, including aerospace engineering and chemical processing.
  • Inconel is difficult to weld because it is resistant to heat and corrosion.
  • In order to weld Inconel, a special welding rod must be used that is made of Inconel or a similar alloy.
  • The welding rod must be heated to a high temperature in order to melt the metal.
  • The welder must then apply pressure to the rod in order to create a bond between the two pieces of metal.
  • The weld must then be cooled quickly in order to prevent the metal from becoming brittle.
  • Inconel welding can be done using either gas-tungsten arc welding (GTAW) or plasma-arc welding (PAW).
  • GTAW is typically used for thicker pieces of Inconel, while PAW is often used for thinner pieces.
  • In order to weld Inconel successfully, it is important to have a clean, well-ventilated work area and to use the proper safety equipment.
  • Welders should also be aware of the potential health hazards associated with welding nickel-chromium alloys and take steps to protect themselves accordingly


In summary, Inconel stick welding is a specialized type of welding process that requires skillful operators who understand how best to use their equipment in order to achieve strong bonds between metals without causing damage or injury. By choosing their electrodes carefully and following all safety guidelines when working with this powerful tool, welders can ensure successful results every time they work with Inconel stick welding machines! With proper training and practice, anyone can become adept at this method – making it an invaluable addition to any shop floor!
