All you have to do is increase or decrease the welding speed. ,...Here, 1. ,For simplicity, omit the heat capacity of the flux existing within the joint capacity in the former pupil. or,
It is difficult to know the amount of welding from flux in relation to the cross-sectional area of the welded LR groove. Therefore, for each groove shape: 1? The optimum condition for the gap amount is determined by experiment for the plate thickness of J, and the optimum condition for the other plate thicknesses of the two-way shape is determined based on this result. .

Among the optimum values of '-l-' I 2''), the relationship between the current ■1, ■1+12 and the capacity/volume of joint 1 when the gap amount is O is determined for Pron 1. From this curve, each joint □
You can select the current 1, +'', and ``L''2 in the hand capacity. □The 0 in Figure 2 above indicates the melting point y (7). If we add the amount of weld from the weld, it should be almost parallel to the straight line of the cross-sectional area of the groove.If we can know the weld end from the flux, we can calculate the current 1 of the third pole and the welding speed from this. Variation of groove cross-sectional area with respect to gap amount: Varies depending on tip shape and forest.

The current I3 of the pole is calculated by multiplying the current I3 after the gap amount O. As the plate thickness increases, the current (3) changes beyond a certain level, and it can be seen that the amount of welding is obtained only by the current (1).

It is a coefficient in mm, and if you follow the plate thickness 2 in the table above,
1 is -90 for 2.5mm, which means that the plate thickness is 22.
In Fig. 2, which plots the optimum welding results obtained in the case of 5mn1, this is the value read from the straight line of the current]I at the first pole, and is the value obtained by comparing the current value 1250Δ when the gap fil Q n+m and the gap amount 1mm. Tokinoden W
This is the value read as the difference between ft and 11111160A. Since the welding current decreases as the gap amount increases in the first pole and second cross-grain, the values of K+ and K2 are set to negative values of 4. In this regard, in the case of the third pole, as the gap amount increases, the welding current increases and the value of K3 becomes a positive value.

The knock-out cannot be unified because the width of the book tip differs in shape, and the joint capacity cannot be unified because the amount of welding cannot be controlled. be. Furthermore, the welding conditions may be controlled by a microcomputer using mathematical formulas as described above, or by

For each current, voltage, and welding speed of the 1st, 2nd, and 3rd poles, file the gear knobs in the microcombi coater as welding threads ('1), and perform the above-mentioned welding according to the changes between the gaps. Since the conditions are controlled, only the gap amount is required as data, and the welding thread f1 is automatically controlled so that a good welding result can be obtained in response to changes in Gillep's strength, and the welding thread f1 is always properly adjusted.
