How to weld Inconel?

Inconel is a highly corrosion-resistant alloy that performs extremely well in extreme environments. Inconel is a registered trademark of the Special Metals family. They are registered as austenitic nickel-chromium-based superalloys.

Inconel alloy maintains high tensile strength even at the melting or burning temperatures of many other golds. Welding is the process of joining separate metal parts together, usually by heating them to their melting point to achieve fusion. When heated, Inconel creates a dense, stable, inert oxide layer that protects the surface from further erosion. Inconel maintains strength over a wide temperature range, which is ideal for high-temperature applications where aluminum and steel can succumb to creep due to thermally induced crystal vacancies.

The excellent and flexible corrosion resistance of Inconel alloys over such a wide range of temperatures and pressures is the main reason for its widespread use in chemical processing. Inconel alloys are oxidation-corrosion resistant components ideally suited for use in extreme environments under high pressure and kinetic energy. When heated, Inconel creates a dense and durable layer of inert oxide that protects the surface from further erosion.

Applications of Inconel Alloy

Inconel alloys are corrosion-resistant superalloys often used in extreme environments, and despite their immense heat and corrosion resistance, the quality of the end product is key. These Inconel superalloys are widely used in the chemical processing, nuclear, petrochemical, aerospace and marine industries. Due to all these properties, Inconel alloy can be used in a variety of applications, including seawater applications.

Use of Inconel can be found in the following industries:

-nuclear reactor

- Flare tower on offshore oil platform

- Components that require exposure to high mechanical stress and seawater

-Pollution control equipment

Tip 1: Weld Inconel using an automatic welding system

Soldering operations done by hand are inconsistent. When a welder enters the process, a few welds may be sloppy, the next few may be the fastest, and most may have problems due to welder fatigue when performing the same motion over and over again.

Advantages of using Inconel automated welding systems include improved consistency, safety and final quality. Rather than having a person carry Inconel electrodes and an arc welder, let them easily set up a robot to supervise hazardous work.

Tip 2: Use Tungsten Inert Gas (TIG)

Many professional welders recommend adding filler material during TIG welding. Although filler material is not typically required for this arc welding method, due to the difficulty of inconel welding, it is recommended to use filler material to hold the two metal parts together without damaging them.

Due to the extremely high melting points of most Inconel alloys, it is often impractical to directly join two Inconel pieces (especially larger workpieces). Instead, the best way to weld Inconel alloys is usually to use a welding process that combines high temperatures with filler materials.

Tip 3: Inconel 625 is a reliable filling material.

Using a metal that is too large for the metal being joined can cause problems such as bimetallic corrosion or differences in thermal expansion at high temperatures. After all, having a “heat-resistant” Inconel basket won’t do you much good if the welds holding the pieces together separate during heat treatment.
