0-60mm HJC60 Universal welding gauges(ROKTOOLS) Range: 0-60mm Part No: WG-407 Manufacturer: Rok International Industry Co., Limited From China Mainland. 1.Measure the height of a flat weld: first align the undercut gauge and the depth gauge to zero and fix the screw; and then move the height gauge to touch the welding spot and see the indicating value of the height gauge for the height of the weld 1.Measure the height of a flat weld 2.Measure the height of a fillet weld 3.Measure the fillet weld 2.Measure the height of a fillet weld: close up the working face of the ruler to the weldment and the welding spot. Move the height gauge to touch the other side of the weldment and see the indicating line of the height gauge for the height of the fillet weld. 3.Measure the fillet weld: the welding spot at 45 degrees is the thickness of the fillet weld. First close up the working face of the main body to the weldment; move the height gauge to touch the welding spot; and see the indicating value of the height gauge for the thickness of the fillet weld. Part No: WG-407 Manufacturer: Rok International Industry Co., Limited From China Mainland. 4.Measure width of the weld: close up the main measuring angle to one side of the weld firstly; then rotate the measure angle of the multi-purpose gauge to close up to the other side of the weld; and see the indicating value of the multi-purpose gauge for the width of the weld.
