NASA reported that failure of a hydrogen line on the nozzle of a Shuttle engine being tested November 4 resulted from use of improper welding wire that "severely decreased the strength of the weld" on a segment of hydrogen line near the base of the nozzle. Rupture of the line caused an oxygen-rich combustion that damaged the test engine. Investigators from MSFC and Rockwell would check all similar welds, using an oxalic-acid etch to identify the weak welds and would decide what remedial steps to take. (NASA Release 79-157)
