CUTTING APPARATUS FOR WELDED PART
BACKGROUND OF THE INVENTION Field of the Invention:
This invention is about cutting apparatus for welded part. That is to say, when
finishing the welded part, the process supporting board of hand grinder contacts the
working surface by rolling to ensure stable support. Under this stable state, the welding
bead is promptly processed by cutting to considerably reduce the working time. And
viewing part is formed at the front and rear center of process supporting board which is
installed at the lower part of head of hand grinder. The viewing part penetrates the
above center so that the worker can visually ascertain the welding bead covered by

Description of the Prior Art: Traditionally, when building ship at the shipyard, convex welding bead formed at the welded part between steel plates of plane surface or curved surface is finished to be eliminated by grinder on which grinding whetstone is installed. In most case, this whetstone is placed on the circular revolving axis which is installed in the head whose front terminal is formed in curve. However, as the conventional grinder cuts little quantity when grinding whetstone contacts the welding bead one time, repetitious grind is required, resulting in considerable inconvenience and long working time.
Moreover, when eliminating the welding bead formed at the welded part by the
conventional grinder, only part of grinding whetstone combined to the grinder contacts
the welding bead and the rest floats in the air. Thus, due to the vibration caused by the
friction between grinding whetstone and welding bead, the grinder itself vibrates or
agitates and the welding bead is not regularly eliminated in uniform height, resulting in
rugged surface.
SUMMARY OF THE INVENTION This invention is about cutting apparatus for welded part. To explain in details,
hand grinder with the following feature is prepared; supporting hand grip at one side
and revolving axis protruded at lower part in the head part formed by cutting at the
forefront. Conical cutter having lateral cutting blade at lateral outer circumference is
combined to the revolving axis of this hand grinder. Process supporting board having
rolling parts such as roller or ball at front and rear side of lower part is installed at the
lower part of head in attachable and detachable type. When finishing the welded parts,
the process supporting board of hand grinder contacts the working surface by rolling.
Under this stable state, the welding bead is promptly processed by cutting to
considerably reduce the working time. And viewing part is formed at the front and rear
center of process supporting board which is installed at the lower part of head of hand
grinder. The viewing part penetrates the above center so that the worker can visually
ascertain the welding bead covered by process supporting board while finishing the
welded part for higher work efficiency. As the lower cutting blade is circularly and slantly formed at the lower part of cutter which is combined to the revolving axis of
hand grinder, welding bead that cannot be easily processed by lateral cutting blade can
be easily cut in vertical direction and the practicality is maximized. BRIEF DESCRIPTION OF THE DRAWINGS
