What Is Weld Cleaning and What Is the Best Way to Do It?


Welding is the mechanical fusing of two metals(usually). Welders are in demand everywhere, as it is necessary for most manufacturing processes. There is a shortage of welders in Australia, as this job requires experience, precision, and skill. Cleaning the welded area is significantly more critical and is a long drawn process. A weld cleaning machine in Australia is a commonly purchased industrial equipment used to clean welds. They don’t disturb the joint area in any way but sanitise it and help in strengthening it. Those working in factories or businesses with metal manufacturing understand the importance of welding and weld cleaning and are also aware of the tedious process.

Why Is Weld Cleaning Necessary?

Before welding the two pieces of metal, they are treated and prepared. During this preparation, the treatment leaves the area vulnerable to rusting or lays the bases for corrosion. The treatment exposes the metal to an increased risk of oxidation and humidity, creating the perfect environment for reducing the metal’s durability. Weld cleaning ensures the strength and purity of the metal post welding and increases the longevity of the joined pieces. 

There are several methods for weld cleaning, and electrochemical weld cleaning is the most efficient. Electrochemical weld cleaning utilises harsh chemicals like pickling paste which thoroughly sanitises the weld. Also, welds are susceptible to corrosion when it is still hot, and during post welding, the metal is still at risk of other types of degradation. But cleaning the weld eliminates those possibilities while also ensuring that there are no heat tints or any other discolouration.

Why Is Electrochemical Weld Cleaning the Best Option?

When it comes to the best type of weld cleaning machine in Australia, the electrochemical cleaning machine comes up as it is equipped to clean the weld using chemical washes efficiently. The chemicals used in this process are generally hazardous to humans, and exposure to them can cause serious problems. Additionally, this process is also long-drawn and requires a lot of patience from the welder. But over the years, several advancements have led to the discovery, or invention, of a much safer electrochemical process of weld cleaning. This process limits exposure to the chemicals, and the chemicals used in the process itself are less harmful. For example, the TIG brush is an innovative method in stainless steel weld cleaning that efficiently cleans the weld while ridding it of imperfections and protecting its integrity.

Electrochemical weld cleaning is the most used method for weld cleaning because it offers several benefits, such as:

  • Maximum Protection Against Corrosion

After intense research and studies, all results repeatedly proved electrochemical weld cleaning to be an excellent option. This method proves especially useful for stainless steel welds, making it the go-to choice for almost all weld cleaning. Also, stainless steel is the most used metal in manufacturing processes which accounts for the widespread use of this method.

  • Fastest Process

Devices like the TIG brush take no more than 5 to 10 minutes to clean and polish small welds. This device passivates the surface as well, making this method one of the fastest.

  • Flexible to Use and Safety

Electrochemical weld cleaning devices like the TIG brush are small and easily portable. Their portability allows for weld cleaning to be done onsite instead of moving the welded metal to a controlled area. Plus, the chemicals and other components used in this method are completely safe for humans.
