1) Develops welding techniques, procedures and applications of welding equipment to problems involving fabrication of materials, utilizing knowledge of production specifications, properties and characteristics of materials and engineering principles.

2) Conducts research and development investigations to develop and test new fabrication processes and procedures, improve existing or develop new welding equipment, develop new or modify current method, techniques, and procedures, discover new patterns of welding phenomena or to correlate substantiate hypotheses.

3) Prepares technical reports as a result of research and development and preventive maintenance investigations.

4) Establishes welding procedures to guide production and welding personnel relating to specification restrictions, material process, pre- and post-heating requirements.

5) Evaluates new developments in welding field fro possible application to current welding problems and production processes.

6) Directs and coordinates technical personnel in performing inspections to ensure the worker's compliance with established welding procedures, restrictions, and standards: in testing welds for conformance with national code requirements; or testing welding personnel for certification.

7) Contacts personnel of other agencies, engineering or clients to exchange ideas, information, or offer technical advice concerning welding matters.
