Back gouging impure welding material between the edges of two parts (generally rolled
plates) partially welded together is a typical application for which this machine is devised.
For a perfect execution it is absolutely vital that the workpiece rotates without drifting
(lateral movements) and if it does you will want to eliminate the problem using some coun-
ter rollers on which the edge of the workpiece can lean against having the counter roller to
act as an end

stop device or you can find other expedients that grant the same result.
Sometimes the grinding disc is not parallel to the welding groove longitudinal axis you ha-
ve to gouge and needs therefore to be slightly tilted so that you can achieve a perfect

groove.
The correct degree is defined by specific charts listed in the following pages, in which are
listed values in relation to the surface width and the desired depth to achieve. Approxima-
tely the value is included between 3° and 8°. In any case it is essential that during the gou-
ging process such angle remains unchanged or that at least is does not increase otherwise
this may generat friction between the grinding disc and the walls of the groove.
