6 FAQs about [Solar support welding standards]
What is the NASA welded standard?
This Standard establishes general directions and describes the type of information that NASA expects for welded structures. This Standard does not provide the detailed process and quality assurance requirements for weldments on flight hardware. Instead, it is intended as a higher level document which states minimum requirements for welded hardware.
What are the requirements for the qualification of welding procedures?
The requirements for the qualification of welding procedures are provided in Clause 4, Procedure Qualification. The requirements for the performance qualification of welders and welding operators are provided in Clause 5, Performance Qualification. This specification also defines and establishes qualification variables.
What are tack welding requirements?
Tack welds that become part of the finished weld shall be performed by certified welders in accordance with certified procedures meeting the requirements of this Standard. After the weldment is completed, the tack areas shall be evaluated to the requirements of the finished weld. Tack welding requirements shall be included in the WPS.
What are the requirements for production welding?
Production welding shall be accomplished according to a qualified WPS. A specific WPS for each weld is required for production welding Classes A, B, and C. Departure from the qualified WPS during production welding shall require withholding the part for MRB disposition. The cause for departure shall be determined.
What parameters should be recorded during qualification welding?
e Specification Example4.5.2.2 Joining Parameters[GWR 51] As a minimum, all essential joining variables (such as voltage, current, rate of travel, position, and filler-wire feed te) shall be recorded during qualification welding.[GWR 52] Manual weld parameters and operating parameter rang
What is acceptable repair welding?
pair Welding4.11.1aAllowable Repair Welding [GWR 116] Additional welding operations shall be permitted to correct any unacceptable condition established per section 4.10, provided the repair welding parameters and procedures are specified in a qualified repair WPS, and t
