Dry welding rods constitute sound welds.
Welding rods proceed differently to moisture. Low hydrogen welding rods, such as 7018s, alter to unreliable when exposed to a customary atmosphere for four hours. Non-low hydrogen welding rods agnate 6011s indicate no contrariness when exposed to moisture. When low hydrogen welding rods are exposed to govern irrigate, you must recondition them before account or the finished weld Testament manifestation defects. Customary defects allow for porosity, hairline cracks and hard up penetration.
Instructions
1. Discover the numbers located near the extremity of the welding rod to bias the rod type.
2. Pride the rod numbers on a drying chart. Locate the reconditioning temperature and time on the chart.
3. Set the temperature of a cooking oven to the designated temperature if the rod reconditioning temperature is less than 500 degrees Fahrenheit. Preheat the oven to the desired temperature. If you are drying more than one welding rod, reduce the temperature of the oven to the holding temperature stated on the drying chart to keep the welding rods at the proper temperature.
Place the wet welding rods into the heated oven.
5. Remove dry welding rods from the oven after the time specified on the drying chart has passed.
6. Set the temperature of a rod oven to the designated temperature for welding rods with a reconditioning temperature greater than 500 degrees Fahrenheit. Turn on the rod oven.4.
