GB2118879A - Electrode holder for welding or gouging - Google Patents

Abstract

An electrode holder suitable for either welding or gouging comprises an outer conductive tube with an apertured end plate to receive a boss 3 on an inner conductive tube the bore 4 of which receives a carbon rod. A hole 2 in the outer tube is aligned with a hole in a non-conductive casing to which a compressed air hose is connected, two holes 5 in an end plate of the inner tube discharging the compressed air on to e.g. a defective weld to remove gouged material. <IMAGE>

Description

SPECIFICATION Electrode holder for welding or gouging Background of the invention Gouging holders have been used in industries conventionally to hold gouging carbon rods to remove defective welds or defects in metals.

Where a defective weld occurs, the welding holder will be replaced with the gouging holder to remove the defective weld, which means two different holders will have to be required at any welding job. This is very inconvenient to the welders as the holders are massive and expensive to carry about whether on ships, workshops or outstations.

Accordingly, it is the object of the present invention to do away with the gouging holder and substitute this invention with the same welding holder to act as gouging holder. It is another object of the present invention to remove the gouged material from the welding site more effectively.

Other features and advantages of the invention will be apparent from the following descriptions of the accompanying drawings.

Brief explanation of drawings Figure 1 is a front view of this invention.

Figures 2 and 3 are the side views of this invention.

Figure 4 is the front view of the metal outer tubing which is a whole machined piece with a hole drilled to insert hose fitting (Figure 7) and a hole drilled in the center.

Figure 5 is the front view of the metal inner tubing which is a whole machined piece with a hole drilled in the center.

Figure 6 is a front view of the non-electrical conductor housing with a hole drilled to insert hose fitting (Figure 7).

Figure 7 is the view of the metal hose fitting.

Detailed description of the disclosure With references to the drawings enclosed, Figures 1, 2 and 3 show the front view and side views of this invention. This invention is a device to use the welding holder and adapt this invention to it and use this new adapted device as a gouging holder, thus removing the conventional massive and expensive holder.

This new device consists of basically four parts as shown in Figures 4, 5, 6 and 7.

Figure 4 shows the front view of the outer metal tubing with one end sealed with a hole (1) drilled atthe center for holding the insertion protruding (3) of Figure 5. A second hole is drilled on the side (2) for the insertion of a hose fitting as shown in Figure 7. Figure 5 is the front view of the inner metal tubing with one end sealed and two small holes drilled on the sides for discharge of compressed air to remove gouged material from surface of defective weld. The hole (4) is for holding the gouging carbon rod. Figure 6 is the front view of the non-electrical conductor or PVC housing with a hole drilled on its side for insertion of the hose fitting (Figure 7).

Figure 7 is a view of the hose fitting for connection to the compressed air supply.

Claims

1. A gouging nozzle assembly consisting of four basis parts only, namely an outer metal tubing with one end sealed with a little hole drilled at its center. The gouging nozzle according to claim is the inner metal tubing with a metal plate attached to one end and a hole drilled through the center of the plate. Two smaller holes are drilled through the sides of the metal plate.

2. The gouging nozzle according to Claim 1 is the inner tubing pressed tight into the outer tubing to form the main part of the gouging nozzle.

3. The gouging nozzle according to Claim 1 is the non-electrical conductor tubing with a hole drilled through its side for hose fitting.

4. The gouging nozzle according to Claim 1 is a hose fitting to supply compressed air through the gouging nozzle and discharged through the two little holes to blow off the molten gouged material.
