WebJul 13, 2024 · If you’re using a welding power source with Auto-Set™ technology, be sure to use the parameters designed for a thinner material, even if you’re welding thicker base metal. This helps keep the heat input lower to fight gravity. A 90-degree travel angle is typically recommended for a 3G weld, while a 45-degree angle is recommended for a 3F ...
WebThe most effective method is to back step or come back down into the crater about ½" (12 mm) and hold for a second before you stop welding. Another technique would involve stepping over to the side of the weld bead and finishing on the side. For slag producing processes, the second method does not require having to weld back into the slag. hardee\u0027s scottsboro alWebApr 21, 2008 · Metal Specialties, Chartered.
