1.0 SCOPE



This process specification provides the minimum requirements that govern the manual arc welding of titanium alloy flight and non flight hardware. Procedural and quality assurance requirements are given. All work instructions and Welding Procedure Specifications (WPS) used during welding shall satisfy the requirements of this process specification and its applicable documents.


2.0 APPLICABILITY



This process specification applies to manual arc welding of titanium alloy flight and non flight hardware that is fabricated under the authority of NASA/Johnson Space Center (JSC) by any of the following types of welding processes:


  1. Gas tungsten arc welding (GTAW)

  2. Plasma arc welding (PAW)


The Gas Metal Arc Welding (GMAW) process is not considered an acceptable process for welding titanium alloys under this process specification.


Future builds of hardware where the existing engineering documentation calls out NASA/JSC PRC-0004 for welding of shall utilize this specification. Existing hardware fabricated to PRC-0014 requirements shall not be affected by this change.
