BS EN ISO 20378:2018

What is ISO 20378- Classification of rods for gas welding about?  

ISO 20378 is an International Standard that discusses welding consumables. 

ISO 20378 specifies a classification for the designation of rods for gas welding of non-alloy and creep-resisting steels in terms of the chemical composition of the rod. 

Who is ISO 20378- Classification of rods for gas welding for? 

ISO 20378 on rods for gas welding is applicable to: 

• Welding consumable manufacturers 
• Automotive and mechanical industry 
• Construction and infrastructure industry 
• Shipbuilding industry 
• Welders and fabricators 

Why should you use ISO 20378- Classification of rods for gas welding? 

Rods for gas welding are used as filler material in gas welding, which produces a high-heat flame at the tip of a gas welding torch by combining oxygen and fuel gas. 

ISO 20378 helps you in the classification of rods for gas welding that can play a positive role in the gas welding processes. The classification is divided into two parts: 

• The first part gives a symbol indicating the product/process to be identified 
• The second part gives a symbol indicating the chemical composition of the rod 

By adopting the classification of rods for gas welding, you can ensure the right product or process is chosen as per the needs of your end-application. This can ultimately help establish efficient welding processes. Moreover, it also creates a harmonized platform for entities across the welding consumable industry, to determine the welding behaviour of rods.
