Welding two 'in the first electric 5 melon start point ρι In addition, a weld mark Sc is formed at an electric arc starting point from the arc opening movement. Thus, the welding and the bottom are sequentially formed to form the welding bubble B. The machine is a result of reducing the scale. Ο Ο In the pin pulse welding, based on the welding m welding = open = coffee initial welding. Secondly, after the welding time passes, stop: in the waiting for the cold material, use the reduced gas cooling welding to deviate from the door gap welder To only start from the arc start point = start point. At the same time 'the same as the arc start point' ^ 仃 及 及 冷却 冷却 冷却 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重 重The welding... In fact, in the vicinity of the arc starting point, specifically in the region from the electric point j to the several arc re-starting points, since the temperature of the material and the welding line is not sufficiently increased, the welding is insufficient. By welding near the point The weld mark S of the mark SC and other places S: ^ $ As shown in the twelfth figure, such as in the region from the arc start point P1 to the electric charge eight start point P3, since the temperature of the base material and the weld line does not rise, The size of the weld mark SC becomes smaller. After the arc re-twist point P4, since the temperature of the base material and the weld line is stable and sufficient =, the size of the weld mark Sc becomes approximately the same. As a result, the k start point The width of the nearby welding bubble Bs becomes narrower than the width of the welding bubble Bt formed after the temperature of the welding line is fixed. 200938327. In order to solve the above problem, the conventional technique is to deviate only a few mm from the starting point of the arc. The location of the material is increased by the usual arc welding, so that the arc welding is started after the arc is stabilized. However, in the case where the normal arc is connected, the welding is performed. The mark is not formed into a scaly shape, and therefore cannot be obtained well. SUMMARY OF THE INVENTION An object of the present invention is to provide a stitch pulse welding method which is to be welded in a predetermined period from the start point of the arc.

The gap is moved to the arc restart point to regenerate the arc at the arc start point, and the weld marks formed by the generation of the arc once are superimposed into a scaly shape, thereby forming solder bubbles on the finished product. According to the stitch pulse welding method, the number of the rod contacts reaches a predetermined initial formation number, and is welded by predetermined initial welding conditions including the initial welding current value, the initial welding voltage value, and the initial welding time.

For example, when the setting 3 is the initial formation number Un, the period for forming the first three weld marks including the arc opening is set as the period during which the initial welding is performed. The initial welding condition Ic is a welding condition for forming a known joint during the initial welding. The specific initial welding current value Ci, the initial welding voltage value Vi, and the initial welding time Ti are specifically shown. Each condition value of the initial welding condition Ic is set to a value which is south of the constant welding condition rpc. Each condition value of the initial welding condition Ic is set based on the experience or experiment of the operator. The reason why the condition value higher than the constant welding condition Tc is set is as follows. The size of the weld mark is determined by the combination of the welding current value, the welding voltage value, and the welding time. For example, the longer the welding time, the larger the size of the weld mark, the shorter the welding time, and the smaller the size of the weld mark becomes. As described in the prior art, since the temperature of the base material and the weld line near the starting point of the arc is not sufficiently raised, the size of the weld mark becomes small. Therefore, for the initial welding, the initial welding condition Ic including the condition value set to be higher than the setting pressure Tc is selected. Specifically, the initial welding current value Ci, the initial welding voltage value Vi, and the initial welding time Ti are set to respective condition values higher than the constant welding condition Tc. Further, different initial welding conditions Ic may be set for each weld mark. In addition, it is also possible to pre-set only the 200938327 arc at the start point of the arc. The arc is automatically calculated from the start point and then the (four) condition for forming the method (four) mark. In the following Langzhong, the money collector's side is formed: ===, and the eye reaches the initial Lu pressure value and welding time. This is regarded as "the constant welding voltage value Vt, and the constant welding level = electric / claw value ct. In addition, the moving speed Sp, the moving door barrier, and the δ load are as follows. The condition described in the conventional technique is tMP, And the cooling time Cd is made to: 13 will weld the control Γ, the initial welding two = ^ ^;: flow; the number of welding control signals of the splicing condition Ic reaches the initial formation number Un until the second 1 trace f number ' In this: the condition values of the soil are gradually reduced to the condition values of the constant = two c (ie, the constant welding current value Tc Vt, and the number of incoming voltage values) After reaching the initial formation number ^, two in the 烊13 will be the constant welding condition Tc round to the welding ^;; the cattle wheel out of control constant pin pulse welding. 窀源WP, and the subsequent control of 13 ^ In order to explain the flow of the itch-connected condition output control unit: the number of the processing 34 reaches the initial formation number un: 4::: start = shift 200938327 line to constant stitch pulse welding foot pulse after welding and processing, Since the migration to a constant needle is in step si, the weld bar #5' is therefore omitted When the number is set to 〇 (zero), the number of formations from the hard disk f=marks Un and the initial welding conditions "^Previous" and the initial conditions (4) (4) Initial welding ❹ The second control unit from the power supply _ from The welding condition output control unit 13 assumes that the welding is not completed, and the process proceeds to step S4. ', and waits as it is, and if the welding is completed, the transfer 13 sets the welding mark in step S4, and the number of welding condition rounding control units is set to + 1. μ In the step %, the welding condition output control unit 13 confirms whether or not the number of welding marks has reached the initial formation number Un. When the number of welding marks is not up to the initial number of formations Un, the welding condition output control unit u = to step S6. A field of several turns is formed when the number of weld marks reaches the initial stage. The lower 'welding condition output control unit 13 moves to step S7. - In step S6, the welding condition output control unit 13 calculates the secondary welding as follows. Condition (ie, secondary reflow current value, secondary reflow voltage value, and secondary reflow time on the next arc start point). When the welding conditions for forming each weld mark are set, The conditional output control unit 13 reads the condition from the hard disk 4. 'The initial welding current value is Ci, the initial welding voltage value is Vi, and the initial welding time is set to be the constant welding current value. Ct, when the constant welding voltage value is vt, the constant welding time is Tt, the initial formation number is Un, and the current welding mark is set to Uc, it can be easily calculated using the following formula. Secondary welding current 11 200938327 Value Cn, secondary welding voltage value v secondary welding current value Cn = Ci and (c person connection time Tn. secondary welding voltage value Vn = VWvi \α) /Un x Uc secondary welding time Tn; _vT; 7/unxuc At the same time, the welding condition output control unit returns the welding condition to the welding power source w, step S2, and the secondary control (4), after the number of welding marks is opened, welds the pieces of output to cover steps S3 to S6. 4屯 The number of Un is up, and the number of weld marks reaches the initial shape: the welding control unit 13 from the hard disk ❹ / (four) day! The welding condition output control unit 13 counts the number of welding marks, and when τ reaches the initial number of formations Un, the welding condition output control unit Tc is output from the initial welding rT:=r==minding welding = formation number Un Welding the power supply, and continue to blame the 'door reference to the third figure to reduce the welding time in the case of the downhill control.

The constant welding condition Tc is a welding condition in which the diameter of the weld mark is stabilized by 0 inches. The initial formation number Un is the number of weld marks required for the diameter of the weld mark to be stable. In the calculation of the constant welding condition Tc and the initial formation number Un, the welding condition calculation unit 23 extracts data corresponding to the diameter Sr of the welded spot to be input from the stabilization time data Ad in each welding condition.

At the time of stabilization, the data Adi is the welding current value = the welding voltage value of 15 V, and the splicing time 〇. 7 seconds. This condition becomes a candidate for J 疋 welding and Te. Further, according to the above conditions, the number of weld marks is "7", which is a candidate for the initial formation number Un. Similarly, the factory material Ad2 is a welding current value of 100A, a welding voltage value of 15V, = time G.7 seconds, and a candidate for the welding condition & According to the above condition, the number of weld marks is five, which is a candidate for the initial formation number Un. When there are a plurality of items waiting for a piece of money, the calculated TC and the number of initial formation numbers are displayed on the display unit 41 of the teaching suspension system tp. At the same time, it is not necessary for the operator to select the constant welding ^ 彡 silk to determine the welding condition Te and the number of initial formation = not right /, one type. For example, the member calculation unit 23 can calculate the constant welding condition Tc and the operator can select it when necessary in the first stage, and the second calculation condition calculation unit 23 calculates the initial welding condition IC. 18 200938327 The above-described processing ' can be calculated as constant welding condition == υη. Then, 'the welding current value of the Adl in the welding of the input' (the fourth), the rod: = 'and the welding time 〇.7 seconds' to calculate the initial formation number is the initial welding of % s of f The method of calculating the condition Ic.焊接 10 The welding condition calculation unit 23 extracts the data of the diameter & 3.5 mm of the weld mark from among the data when the number of the material marks in each welding condition is one. If the diameter Sr of the weld mark is not 3.5 mm, the welding condition calculation unit 23 extracts the data closest to the diameter Sr of the welded weld mark. In the case of the conditional database 24 shown in Fig. 7(a), the welding condition calculation unit 23 selects the data Bd1 whose diameter of the weld mark is 3.5 mm. Based on selected data
Bdl與穩定時資料Adl，焊接條件算出部23自動地算出 初期焊接條件Ic。 如第八圖之(a)所示，第一個焊接痕的焊接條件被設 疋成與資料Bdl相同的條件。第七個及第八個以後的焊 接痕的焊接條件被設定成與穩定時資料Adl相同的條 件。同時，如第八圖之(a)的底線部所示，第二〜六個焊 接痕的焊接條件均等地分割資料Bdl及穩定時資料Adl 間的焊接電流值，其設定可使得焊接痕的數目越多則焊 接電流值便越低。 另外’在上述的例子中，雖然是選擇資料Bdl並基 於此資料Bdl與穩定時資料Adl，均等地分割兩者的焊 接電流值以自動地算出初期焊接條件Ic，但其替換方式 為’亦可選擇焊接痕的直徑是3.5mm附近的資料Bd2。 在此場合下’如第八圖之(b)所示，第一個焊接痕的焊接 條件被設定成與資料Bd2相同的條件。第七個及第八個 19 200938327 以後的焊接痕的焊接條件被設定成與穩定時資料Adl相 同的條件。同時’如第八圖（b)的底線部所示，第二〜六 個焊接痕的焊接條件均等地分割資料Bd2及穩定時資料 Adl間的焊接時間，其設定可使得每當焊接痕的數目增 加時可階段性地縮短焊接時間。 同時，知接條件异出部23將算出的初期形成數 Un、初期焊接條件ic、及恆定焊接條件Tc記憶於硬碟 4。以後的處理由於皆與第一實施形態相同，因此省略 其說明。 如上所述，在第二實施形態中，藉由預定與泡寬度 相當的焊接痕的直徑的期望值，並將此焊接痕的直徑輸 入至焊接痕的直徑與恆定焊接電流及恆定焊接電壓的 關係被預定之焊接條件資料庫，便可自動地算出初期形 成數、初期焊接條件、及恆定焊接條件。因此，除了能 夠固定在電弧開始點附近的焊接泡的寬度，還能夠減低 焊接條件的設定工時。In the Bdl and the stabilization time data Ad1, the welding condition calculation unit 23 automatically calculates the initial welding condition Ic. As shown in (a) of the eighth figure, the welding conditions of the first weld mark are set to the same conditions as the data Bdl. The welding conditions of the seventh and eighth subsequent weld marks are set to the same conditions as the stable data Ad1. Meanwhile, as shown in the bottom line portion of (a) of the eighth figure, the welding conditions of the second to sixth weld marks equally divide the welding current value between the data Bd1 and the stable data Adl, which is set such that the number of welding marks The more the welding current, the lower the value. In addition, in the above example, although the data Bdl is selected and the welding current value of both is equally divided based on the data Bdl and the stabilization time data Ad1, the initial welding condition Ic is automatically calculated, but the alternative is ' The diameter of the weld mark was selected to be the data Bd2 near 3.5 mm. In this case, as shown in (b) of the eighth drawing, the welding condition of the first weld mark is set to the same condition as the data Bd2. The seventh and eighth 19, the welding conditions of the weld marks after 200938327 are set to the same conditions as the stability data Ad1. At the same time, as shown in the bottom line portion of the eighth figure (b), the welding conditions of the second to six weld marks equally divide the welding time between the data Bd2 and the stable time data Ad1, which is set such that the number of weld marks each time When added, the welding time can be shortened step by step. At the same time, the known condition dissipating unit 23 memorizes the calculated initial formation number Un, the initial welding condition ic, and the constant welding condition Tc on the hard disk 4. Since the subsequent processing is the same as that of the first embodiment, the description thereof will be omitted. As described above, in the second embodiment, the relationship between the diameter of the weld mark and the constant welding current and the constant welding voltage is determined by the predetermined value of the diameter of the weld mark corresponding to the bubble width, and the diameter of the weld mark is input. The initial number of formations, initial welding conditions, and constant welding conditions can be automatically calculated from the predetermined welding condition database. Therefore, in addition to the width of the welding bubble which can be fixed near the starting point of the arc, the setting man-hour of the welding condition can be reduced.
