Abstract

PURPOSE:To enable a welding operator to engage exclusively in the monitoring of a weld zone and to permit the operation with min. personal by converting the values of the measured welding conditions to sound signals and indicating the conditions by voices to the operator. CONSTITUTION:An arc is generated between a coated electrode 2 and a bar 3 to be welded on starting of welding. Current and voltage are measured by a welding current measuring instrument 6 and a welding voltage measuring instrument 7 and the output electric signals from the instruments 6, 7 are inputted to a voice converter 8. The converter 8 converts the electric signals of the welding current and welding voltage to voices according to the values thereof and the welding conditions in this stage, i.e., the welding current and welding voltage in this embodiment are announced to the operator 4 by a voice output part 9 such as speaker.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a welding condition measuring device that measures welding conditions during welding work and displays the values.

[Conventional technology]

In general, in welding work, it is necessary to ensure that various conditions for welding work, such as welding current, welding voltage, and welding speed, are set to specified values, and also to check them.

[Problem that the invention seeks to solve]

However, except in fully automated welding equipment, the welding operator must constantly monitor the weld while the weld is in progress, and the gauges displaying welding conditions are often difficult to read.

[Means and effects for solving the problem] The present invention provides a means for visually confirming the measured welding conditions by displaying them on the instrument surface, converting the values of the measured welding conditions into audio signals, This is a means of notifying the worker with audio and giving him 1 second confirmation, which allows the worker to check the welding area while welding is in progress.
In addition, for arc welding, the present invention provides a welding condition measuring device that can be used to monitor the melting state of the tip of the electrode rod, the welding position, etc.

〔Example〕

Hereinafter, details of one embodiment of the present invention will be explained with reference to the drawings.

Although the figure shows shielded arc welding as an example, it can be similarly applied to arc welding.

Further, here, shielded arc welding is taken as an example, and the configuration is shown assuming that two conditions, welding current and welding voltage, are monitored as welding conditions.

In the figure, numeral 1 is a welding power source, which may be any type of power source, such as direct current, alternating current, or one with superimposed pulses. 2 is a covered arc rod, 3 is an object to be welded, and 4 is a welding operator.

Further, 5 is a current measuring shunt or a current transformer. 6 is a current measuring device, which can generate an output signal according to a measured value.

7 is a welding screw pressure measuring device, which can generate an output signal according to the measured value. Reference numeral 8 denotes an audio converter, which receives the electrical output signals from the measuring devices 6 and 7 and generates audio according to the value of the signals, and has a built-in speech processor.

Reference numeral 9 indicates an audio output section such as a speaker or headphones that emits audio output into the air.

Here, the operation of one embodiment will be explained. Now, when the welding operator 4 starts welding and an arc is generated between the covered arc welding rod 2 and the workpiece 3 and welding starts, the welding current measuring device 6 and welding voltage measuring device 7 , respectively current,
The voltage is measured, and the electrical signals output from each of the measuring devices 6.7 are input to the audio converter 8. The audio converter 8 converts the electric signals of the welding current and welding voltage into audio according to their values, and transmits the welding conditions at the time to the operator (i.e., the welding conditions shown here) using the audio output section 9 such as a speaker or headphones. In the example given above, it informs the welding current and welding voltage.The timing of the sound can be adjusted, and the interval can be varied.As an example of the sound generation, "1 current 250 ampere 1", "'voltage 25" A fixed (unchangeable) part of these sounds such as “volt 1” is generated.
"○○ ampere" and "voltage O○ volt" can be set arbitrarily in advance, and only the "ooo" part is changed and uttered according to the measured signal.

〔Effect of the invention〕

As described above, according to the welding condition measuring device of the present invention, in order to confirm the welding conditions, the welding operator has to take his eyes off the welding part and recognize the indicated value of the meter, and the welding condition can be read by voice. This allows the worker to concentrate on monitoring the welding part, and also allows the work to be carried out by fewer people without the need for a worker to read the meter.
