Welding repair of holes in distribution boxes

First, ensure sufficient gas coverage and flow rates of 8 L/min for TIG welding and 10-12 L/min for MIG welding to manage porosity. Clean the metal, including the inside edge of the hole, to prepare for a proper. Why is the welding process of metal distribution boxes extremely important? In the manufacturing process of metal distribution boxes, welding constitutes a critical stage following sheet metal cutting and bending. We have a W12 x 190 with 4 x 13/16" bolt holes that our Peddinghaus drill line "mysteriously" drilled 1" offset from where they should be.
