Detailed description of the invention
The gas-shielded arc welding apparatus 100 of present embodiment, as shown in Figure 1, has: welding torch 110; The source of welding current 120; Welding wire supply unit 130; Protective gas supply unit 140; Moving distance measuring member 510; Weld heat input calculation unit 520; Weld heat input display part 530; Voice output converter section 540.
The source of welding current 120 supplies electric power between welding torch 110 and the steel plate 200 as soldered portion.Welding wire supply unit 130 supplies welding wire continuously to welding torch 110.The quantity delivered of welding wire is regulated from outside by remote control 210.
Its formation of protective gas supply unit 140 has: tank body 142; Gas flow regulating valve 141; Tracheae 143, supplies the protective gas sprayed from welding torch 110.Protective gas is such as CO
2monomer gas or CO
2with the mist of Ar gas.
Moving distance measuring member 510 measures the displacement in the sealing wire direction of welding torch 110.Specifically, moving distance measuring member 510 such as can be made up of optical sensor.This optical sensor has the irradiation portion 511 steel plate 200 being irradiated to laser, and detects the test section 512 of the laser reflected by steel plate 200.Irradiation portion 511 is optical illumination portions that such as computer optical mouse adopts, and mechanism is identical.Optical sensor makes the change of the atomic sight on shone thing surface amplify, and obtains the planar movement range information of moment.
On the other hand, as shown in Figure 2, be built in the traveling time determination part in the source of welding current 120, measure traveling time when this welding torch 110 moves in described displacement.Then, the translational speed calculation unit being built in the source of welding current 120, according to this displacement and this traveling time, tries to achieve the translational speed in the sealing wire direction of welding torch 110.
Then, weld heat input calculation unit 520 calculates weld heat input by this translational speed, weldingvoltage, the source of welding current based on following formula 1.
[formula 1]
Weld heat input Q (J/cm)=[electric current (A) × voltage (V) × 60/ speed of welding (cm/ divides)
Weld heat input display part 530 moment, namely show the weld heat input calculated in real time.The display of weld heat input is shown by analogue instrument or digital instrument.Further, also can be shown by analogue instrument or digital instrument two side.
Voice output converter section 540 has: sound converter section, and it converts the weld heat input that weld heat input calculation unit 520 is calculated to voice signal; Efferent, the weld heat input being converted to voice signal by sound converter section externally exports by it.Voice output converter section 540 and unlike weld heat input display part 530 moment (in real time) display weld heat input, but send sound at certain intervals.By voice output converter section 540, welding person need not watch weld heat input display part 530 often just can confirm weld heat input constantly, and the management of weld heat input becomes easy.
As shown in Figure 1, welding torch 110 is provided with temperature-measuring member 310.Temperature-measuring member 310 radiates thermometer specifically, in a non contact fashion the steel billet temperature in the real time measure electric arc nidus field.The steel billet temperature measured, by the temperature display section 320 be located on the source of welding current 120, is shown in real time by analogue instrument or digital instrument.Further, also can show with analogue instrument or digital instrument both sides.
Further, weld heat input display part 530, temperature display section 320, sound conversion efferent 540 not only can be located at welding machine main body, and can be located at such as be arranged on feed apparatus, Current Voltage controller or independently device etc. any one.
On the source of welding current 120, be provided with the storage part 610 storing construction resume.There is the temperature etc. near position in the electric arc of the steel plate 200 when the object stored such as has the open and close moment of electric arc, welding current, weldingvoltage, the translational speed of welding torch 110, weld heat input, electric arc to start.
Next, the operation for the present embodiment formed as described so is described.Moving distance measuring member 510 measures the displacement on the sealing wire direction of welding torch 110.Welding torch 110 not only moves in sealing wire direction, and carry out with being called as teeter (weaving) or swinging the work of (oscillating) of sealing wire direction at a right angle.Therefore as shown in Figure 3, the vector of the movement representing welding torch 110 is divided into sealing wire direction (Y) and vertical direction (X), uses the information computational speed of the distance of Y-direction.Thus, welding operator or management can according to welding current, weldingvoltage real time monitoring as the weld heat inputs of conclusive key factor.
Its reverberation, towards the vertical lower irradiation LED of welding torch 110 or laser, is collected test section 512 and is detected by irradiation portion 511.In this case, laser is preferably less than 10 degree relative to the vertical direction on described surface for the incidence angle on the surface of steel plate 200.
When needing high sensitivity as mouse, although the method for the incidence angle of oblique light can reach high sensitivity, but when welding torch 110, from irradiation portion 511 to reflecting surface, namely steel plate have very long distance, if therefore incidence angle is large, then irradiation portion 511 is elongated with the distance of test section 512, is physically difficult to be installed on welding torch 110.But sensitivity is not raised so high necessity in calculating by the speed of welding when welding, and therefore incidence angle also can be little.Therefore, incidence angle specific requirement is advisable below 10 degree relative to vertical direction.
Then, if confirm or sound confirmation through display, it is in limited time upper that weld heat input soon exceedes permission, and operator can weld the counter-measure taking to reduce welding current or weldingvoltage immediately.Just in case when exceeding allowed band, also can stop welding immediately, only this part be removed with gouge (gouging) or grinding machine (grinder) etc., and again recover welding operation.
On the other hand, in the present embodiment, to measure and the electric arc showing steel plate 200 occurs near position temperature.So, steel billet temperature is measured in a non contact fashion with temperature-measuring member 310, be presented on temperature display section 320 in real time, therefore have in mensuration face during the attachments such as spatter and also can monitor steel billet temperature, worsening with estimating precision or needing to carry out spatter removes compared with the mensuration utilizing contact tehermometer to carry out of the existing formula operated, without the need to the measurement operation of complexity.
In addition, be stored in the construction resume of storage part 610, i.e. weld heat input, translational speed, weldingvoltage, welding current, can make it by cable 620 efferent 630 outputting to PC etc.Further, to the output intent of efferent 630, method that such as USB storage, SD card, disk, CD, wireless connections etc. are various can be enumerated to replace cable 620.
So, according to the present invention, even if manager does not directly come to welding scene personally, also welding operation can confirmed after a while.Therefore, no matter when can follow the tracks of for the welding condition of welding position, reliability improves further.
