do all metal boxes need to be grounded Metal junction boxes always need to be grounded, whether you're using NM (non-metallic) plastic-sheathed cable or metallic cable. Metallic cable is self-grounding, as long as . Industrial users typically prefer Fleetweld® 35. This all-position, AC electrode is used for welding clean, new sheet metal. Its soft arc has minimal spatter, moderate penetration and an easy-to-clean slag. Lincoln Fleetweld® 37 is most common of this type.

For welding purposes, the term “sheet metal” is restricted to thicknesses of metals up to and including 1/8 in. (3.2 mm). Welds in sheet metal up to 1/16 in. (1.6 mm) thick can be made satisfactorily by flanging the edges at the joint.Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt materials . See more
