Why choose ISO14175 compliant welding gases from Energas?

Energas is fully committed to supply products that meet the required standards and compliance for manufacturing and our customers. Energas fully embrace EN ISO14175:2008 Welding Consumables - Gases and gas mixtures for fusion welding and allied processes as the key standard for reference for the production of welding gases for the UK market.

It is important to understand the criteria for gas specifications applied with ISO14175:2008 classification and designations to ensure compliance with customer needs and Weld Procedure Specifications as shown in the table below:
