           The electrode angle of 45° will help to fuse both plates equally and the 80° angle will help to get a good root
           penetration.
           Proceed along the welding line with uniform travel speed and short arc to get uniform fusion and root penetration.

           The slag has to be removed thoroughly from the root run so that the slag inclusion defect can be avoided in the
           next run.
           Use a slightly side-to-side weaving motion. (Fig 3) The width of weave should give a leg size of 10mm.
