Weld crew initiated an argon purge on a 30" pipe that had been fit up afternoon prior. When argon purge was established, two welders began to make their root pass welds. Upon inspection "sugaring" was observed. a welder entered the open end of the 30" pipe for unknown reasons where they were found by a coworker to be unresponsive. No witnesses observed them enter the pipe.
