<The explanation of welding condition>
Then, the condition of weld job, the welding bar stored in memory 21 internally and external memory storage 151 are illustrated Part.User can be set using control box 15 or change welding condition, and welding condition includes such as welding current, pulse electricity Stream, MC electric currents, weldingvoltage, two ends crest voltage, speed of welding, welding wire feeding speed, peak value welding wire feeding speed, vibration speed The data such as degree, vibration dwell time, oscillation amplitude, turning height, side-play amount.
Welding current is the electric current between the electrode in weld job and mother metal B.In the present embodiment, welding current can Be exchange, or direct current.In addition, in the case where welding current is direct current, welding current can also be pulse.Specifically For, it is different that pulse output exports content in " when directly welding " with the setting of " during vibration welding ".It is being set as directly weldering In the case of connecing, according to the timing of pulse frequency, welding current is switched to low current (hereinafter referred to as reference current) and height Electric current (hereinafter referred to as peak point current), as the welding of common pulse current.On the other hand, the feelings when vibration welding is set as Under condition, when vibration end when electrode vibrates stops, peak point current is switched to.Additionally, for example because of the thickness of slab or species of mother metal B It is different Deng, welding condition, thus peak current value, pulse period of the welding current when being pulse etc. can according to welding when environment To set.
MC electric currents are the electric currents being powered to filler wire in weld job.Weldingvoltage is electrode and mother metal in weld job Voltage between B.Additionally, two ends crest voltage is electrode stops the voltage that phase is added on weldingvoltage in vibration end.Vibration When end stops, the voltage of the setting value by being added two ends crest voltage in the setting value of weldingvoltage carries out AVC controls System.
Speed of welding is the travel speed of the chassis 14 in weld job.Welding wire feeding speed is the jogging of filler wire (inching) speed of filler wire and during weld job, is fed from feedway 13.Peak value welding wire feeding speed is that electrode exists Welding wire feeding speed when vibration end stops, in vibration end stopping, welding wire feeding speed is changed to increase and decrease and peak value welding wire The setting value of feed speed measures resulting speed accordingly.
Hunting speed is the speed of electrode when twin shaft sliding block 12 vibrates electrode.Vibration dwell time is in electrode vibration When electrode left or right vibration end stop time, have left end dwell time and right-hand member dwell time.Oscillation amplitude is The oscillation amplitude of electrode when twin shaft sliding block 12 vibrates electrode.In the present embodiment, the weldering for changing as the elapsed time One of narrow bars part, uses oscillation amplitude.Oscillation amplitude will in detail below be described.
Turning height is the height risen with the shape of groove face, is in groove profiling (Open elder generations Imitation い) in for slope Threshold value in mouth detection.Turning height has left end turning height and right-hand member turning height according to the left end and right-hand member of vibration end. Side-play amount is electrode during vibration end stops makes the amount that electrode moves from vibration end, according to vibration end have left end side-play amount and Right-hand member side-play amount.
<The explanation of oscillation amplitude>
Then, illustrate as the oscillation amplitude of welding condition.Fig. 3 is for illustrating the figure of the one of oscillation amplitude.Such as Fig. 3 Shown, the electrode that welding torch 11 is kept is moved according to the moving direction (direction of arrow A1) of chassis 14.Now, twin shaft sliding block 12 for example are vibrated to vibrate electrode along the direction of arrow B1 and the direction of arrow B2 so that along the groove of mother metal B Shape accurately welded.As described above, the distance at two ends of vibration end when electrode vibrates is oscillation amplitude.In figure In example shown in 3, as the example of oscillation amplitude, represent at the two ends of the vibration end sometime put apart from L1, apart from L2.
Here, because the welding position of mother metal B changes with the shape of mother metal B, thus oscillation amplitude also with The process of time and change.Control panel 20 determined according to the shape of mother metal B should traveling electrode amplitude, control twin shaft Sliding block 12 causes that electrode is based on determined amplitude and vibrates.Additionally, from when welding starts, every the 1st time or the 2nd time, The oscillation amplitude that the corresponding moment determines by control panel 20 is internally stored in memory 21 or external memory storage 151.
<The explanation of the picture that display part shows>
Then, the picture that the display part that control box 15 possesses shows is illustrated.Fig. 4 is the display part for illustrating control box 15 The figure of of shown picture.In the picture shown in Fig. 4, " welding current ", " P electricity are shown as welding condition Stream ", " hunting speed ", " speed of welding ", " left end stoppings ", " moving to left ", " left upset height ", " PW speed ", " weldingvoltage ", " MC electric currents ", " oscillation amplitude ", " wire speed ", " right-hand member stopping ", " moving to right ", " right upset is high ", " two P voltages ".Also, it is each The setting value of welding condition is displayed on by the word of each welding condition.
In the picture shown in Fig. 4, " welding current " is the setting value of welding current, and " P electric currents " is pulse current welding The setting value of the peak point current of where applicable, " hunting speed " is the setting value of hunting speed, and " speed of welding " is speed of welding Setting value, " left end stopping " is the setting value of left end dwell time, and " moving to left " is the setting value of left end side-play amount, " left upset is high " It is the setting value of left end turning height, " PW speed " is the setting value of peak value welding wire feeding speed.Additionally, " weldingvoltage " is weldering The setting value of voltage is connect, " MC electric currents " is the setting value of MC electric currents, " oscillation amplitude " is the setting value of oscillation amplitude, " welding wire speed Degree " is the setting value of welding wire feeding speed, and " right-hand member stopping " is the setting value of right-hand member dwell time, and " moving to right " is right-hand member side-play amount Setting value, " right upset high " is the setting value of right-hand member turning height, and " two P voltages " is the setting value of two ends crest voltage.
Also, in the example of diagram, welding current is set to 100 amperes of (units of electric current:A), peak point current is set It is set to 0A, hunting speed is set to 100cm/min (cm per minute), and speed of welding is set to 5.0cm/min, it is left End dwell time is set to 1.0 seconds, and left end side-play amount is set to 0.0mm.In left end turning height, it is multiplied in setting value Numerical value obtained from 0.05 turns into actual left end turning height (mm), when setting value is 5, is set to 0.25mm.Peak value In welding wire feeding speed, the numerical value obtained from 10 that is multiplied in setting value turns into peak value welding wire feeding speed, when setting value is 0, It is set to 0cm/min.Additionally, weldingvoltage is set to 12.0 volts of (units of voltage:V), MC electric currents are set to 40A, oscillation amplitude is set to 15.0mm, and welding wire feeding speed is set to 100cm/min, and right-hand member dwell time is set to 1.0 seconds, right-hand member side-play amount be set to 0.0mm, in right-hand member turning height, be multiplied in the setting value numerical value obtained from 0.05 into It is right turning height (mm) that setting value is set to 0.25mm when being 5, and two ends crest voltage is set to 0.0V.Here, on Each welding condition shows the value of user's setting or change, on oscillation amplitude, as described above, shape according to mother metal B and The value for the elapsed time being shown in control panel 20 and being determined.
Additionally, in the picture shown in Fig. 4, as the error message on cooling water, it is shown that " welding starts preceding detection To the exception of cooling water " word.In addition, the literature record of " origin terminates " recovers to advance by welding torch 11 or the grade of chassis 14 Black and white conversion is carried out at the end of the treatment that the origin of the origin of determination recovers (background is black, and word is white).Also, in figure In picture shown in 4, for example, user's pressing operation button etc. selects the project of " welding current ", user can also be grasped Make to change the setting value of welding current.
<The explanation of the storage method of welding condition>
Then, illustrate that welding condition storage is arrived internal storage 21 and external memory storage by control panel 20 in weld job 151 method.Fig. 5 is illustrated welding condition storage to of the method in internal storage 21 and external memory storage 151 The flow chart of example.Here, inserting external memory storage 151 to control box 15.Additionally, user is before weld job is started or welds In operation, the setting or change of welding condition are carried out beneficial to control box 15, welding condition is shown in the display part of control box 15. In addition, user is when weld job is started, the servomotor of position, the speed of welding torch 11 or chassis 14 etc. will be controlled to connect Recover the grade of welding torch 11 origin.
First, if user presses the behaviour for starting weld job for accepting among the operation button that control box 15 possesses The operation button of work, then control panel 20 accepted via control box 15 welding start operation (step 101).If here, not having External memory storage 151 is inserted into control box 15, then the display part in control box 15 shows mistake.If control panel 20 has accepted weldering The operation of beginning is connect, then controls the action of welding torch 11, chassis 14 etc. based on welding condition set in advance to start welding work Industry, and moment (hereinafter referred to as welding start time) and the welding bar for having started weld job are internally stored in memory 21 The setting value (step 102) of part.
Then, control panel 20 is internally stored when have passed through predetermined 1 time from welding start time every time The welding condition for weld job is stored in device 21.Here, control panel 20 determines whether to have passed through for the 1st time (step 103), When have passed through for 1 time every time ("Yes" of step 103), the welding bar for weld job is internally stored in memory 21 Part, the welding condition (step 104) for being set at the corresponding moment.On the other hand, if not by the 1st time (step 103 "No"), then control panel 20 does not internally store welding condition in memory 21.
Additionally, control panel 20 from welding start time when predetermined 2 time has been begun to pass through every time, in operation The welding condition that internal storage 21 is stored is stored in the external memory storage 151 of case 15.Here, control panel 20 determine whether through Spent for the 2nd time (step 105), when have passed through for 2 time every time (step 105 "Yes"), having read storage at that moment and existing Welding condition in internal storage 21, stores the welding condition (step 106) of reading in external memory storage 151.Here, outer Portion's memory 151 stores welding condition in the form of master data and subdata, as subdata, with every the moment of the 2nd time Used as sampled point, storage welding condition is used as the file split by sampling time point.Also, power supply disconnect etc. and cause it is different When often stopping, stored subdata is not deleted and is to continue with portion's memory 151 outside and is preserved.On the other hand, if not passing through 2nd time (step 105 "No"), control panel 20 does not store welding condition in external memory storage 151.
If here, for example, the 1st time was set into 1 minute, was set to for the 2nd time 5 minutes, from start time is welded Welding condition internally just was stored in memory 21 every 1 minute.Additionally, transmitting inside to external memory storage 151 every 5 minutes The data of the welding condition that memory 21 is stored, store in external memory storage 151.
Then, control panel 20 determines whether to have accepted the operation (step 107) for stopping weld job.Here, for example, with In the case that the operation button for accepting the operation for stopping weld job being pressed at family, control panel 20 is received via control box 15 The operation (step 107 "Yes") that reason welding stops, stopping welding torch 11, chassis 14 etc. to stop weld job.Additionally, control panel 20 Internally storage stopped the moment (hereinafter referred to as welding the stop timing) of weld job and in moment setting in memory 21 Welding condition (step 108), terminate this handling process.On the other hand, if not accepting the operation (step that welding stops 107 "No"), then step 103 is transferred to, then, control panel 20 is every storage welding article in the 1st time internally memory 21 Part, welding condition is stored every the 2nd time in external memory storage 151.
Additionally, in the method shown in Fig. 5, user presses the operation button for accepting the operation that weld job starts, So as to start while weld job, also start to store the treatment of welding condition, but be not restricted to that this structure.Example Such as, it is also possible to be separately provided for starting the operation button of storage.In addition it is also possible to welding current, weldering when being started with welding The rising edge of voltage is connect for opportunity, starts the treatment for storing welding condition.If in addition, by pressing the behaviour that weld job starts Also start the storage treatment of welding condition as button, be then prevented from user and forget situation or treatment mistake of operation etc..Together Sample, is expected that by the operation button that user presses the operation for accepting weld job stopping, so as to also stop welding condition Storage is processed.
In addition, interval, i.e. the 1st time, the 2nd time of storage welding condition can be changed by user.If for example, the 1st Time is less than 1 second, then the data volume of the welding condition to be recorded is huge, needs to carry out long-time more than half a day in weld job In the case of, whole resume cannot be left in external memory storage 151 sometimes.Additionally, data volume is huger, can more lose Confirm the simplification of the operation of the record that user is carried out.In addition, from confirm record precision from the viewpoint of, if at least every Obtain a data for welding condition within 600 seconds, be then able to confirm that the trend of arc stability.It is therefore preferable that at 1 second to 600 seconds In the range of specify the 1st time.
