Another thing to mention is the runout at the bottom and tops of each pass. The cap must not be below parent material in these areas at all. Always wire wheel or wire cup between passes. Any of these being missed is an automatic fail if an arc is struck on Un cleaned welds. The testing facilitator should be watching for these habits, and briefing on them prior to testing. Great video. Very well made.
Why is there zero info about the written exam??? I passed the 3g 4g weld test but I can’t find ANYthing on the written exam with open book/closed book.
