Standards Development

It is essential that you understand and correctly apply the documents that specify the minimum acceptable level of safety, and engineering or technical requirements for your products, practices and operations.

Codes and standards are a key feature of welding, joining and ancillary operations. TWI shares responsibility for their development, review and update:

Standards development – TWI actively participates and inputs into around 100 national and international committees.

Standards updates – When codes and standards are updated by governing bodies, TWI provides updates to Industrial Members through summary articles; and by direct feedback through our technical enquiry service.

Guidance on the application at all stages: design, manufacture and operation; including all relevant welding engineering standards.

Support on interpretation – Contact our engineers with any questions relating to interpretation of codes and standards for your particular application.
