Welding Rod Length. The third digit tells you about the positions in which that welding rod can be used. The optimal arc length or distance between electrode and puddle is the same as the diameter of the electrode the actual metal part within the flux covering.
The welding rod is the piece of wire connected to the welding machine. Welding Supplies Direct stock a range of welding electrodes from various brands including Bohler Welding Elecrodes SIF Super 6 UTP Hilco. 800 842 7839 570 459 0771 Fax.
To achieve the correct arc length using 32mm rods the distance between the flux coating on the rod and the flux on top of the weld might be less than 1mm.
It catches the surface very well. Lets say you are using a 564 inch E6013 rod at the right amperage value but still your filler rod keeps sticking to the base metal. Suitable for welding Mild steel plate sheet metal and galvanised iron sheet ducting hoppers tanks pipes and low pressure pipelines. ESW is a highly productive single pass welding process for thicker materials between 1 inch 25 mm and 12 inches 300 mm in a vertical or close to vertical position.
