Choosing the best way to clean your Tig Welds . . .

by Admin 11. September 2019 09:07

Effective finishing and cleaning of a Tig weld is a crucial part of the post welding process.

The welding process can cause discolouration, heat tints and burn marks. Removing these can subsequently improve corrosion resistance, which in the long run will increase the durability of a weld and preserve the physical properties of the metal surface and weld.

When produced stainless steel has a chromium oxide film which is formed on the surface during production. The fabrication process can damage this film through scratches, the formation of surface oxides and embedded iron, this causes areas of lower corrosion resistance. To restore the protective surface areas can be treated and cleaned.


Pickling Paste

The traditional method of using pickling paste is slowly being filtered out due to the time-consuming method and potentially dangerous chemicals involved. If pickling paste is the chosen method, it is important to ensure the correct procedures are in place. These can be found of the HSE website by clicking here.

Electrolytic Weld Cleaning

Electrolytic weld cleaning is the ideal cost-effective solution to ensure clean and durable welds. This is an extremely quick solution and considered to be very safe in comparison to the hazardous process of applying pickling paste or exposure to excessive amounts of grinding dust.

The electrolytic weld cleaning process is very simple. An electrolytic cleaning fluid is applied to the surface of the weld using a conducive welding brush. When the electric current is applied the desired effect of cleaning and passivation occurs. This is a quick process which removes the iron-based oxides from stainless steel Tig welds, leaving the bright finish on the weld.
