When electrical current is applied to the inside of the wire (4) at the same time as the short circuit with f91, the wire (4) is preheated, and when it reaches the base metal 191, it is almost melted, and the base metal (4) heated in advance by the arc +71 (
9) will be deposited in the form of a bead.
従来の装置は以上のように構成されておシ。The conventional device is configured as described above.

流が切れてワイヤが冷えてし甘うためワイヤ（４）から
母材（９）への溶融移行が不連続となり。Therefore, when the no-load voltage of the power supply (6) is low, the direct current to the wire is cut off and the wire cools down, resulting in discontinuous melting transfer from the wire (4) to the base material (9).

In this way, in the conventional device, the power transmission and feeding of the wire and the wire must be completed independently, and it takes a long time to make the lytic transfer from the wire to the ff3-shrine. Line and time 1iJ were required.

(5) When the feeding speed of the wire (4) is increased, the wire current must also be increased.Therefore, depending on the wire feeding power i Vw, the wire ( In order for 4) to reach the base material (9),
The potential difference between the power supply device t101 and the base material f91 needs to be maintained at an appropriate value VO according to the wire feeding speed Vw.

If V increases as a result of increased spiral force resistance in a section, the wire basket flow must be completely lowered to slow down the wire melting speed.
If the wire becomes too low, the wire DC current must be increased to increase the melting rate of the wire. The wire diameter is 1 in the drain diagram 3.

きる。(On the other hand, there is an experimental fact as follows regarding the appropriate relationship between the heat input t to the base material f91 and the amount of excess of the bead (8). In other words, the thickness of the f# material, the welding current When is kept constant, the appearance of the bead changes depending on the welding speed and wire feeding speed.The base material is 1 mild steel with a plate thickness of 3.2 mm, the wire diameter is 12 groups, the arc current is 300 A, and the arc length is 32 rules. When the wire (4) is melted, the wire (4) is just exposed to the base material (

ワイヤ送給速度の適正範囲に注目してみる。In area (b), the mallet area where the heat input to the base material (9) is appropriate and a stable bead can be formed, the wire feed rate is too large and the bead becomes convex and the base metal 19) and bead +81
The welding speed is too low and the welding speed is too high, and the area (d) is the area where the welding speed is too slow and the wire (7) is a welding area where undercuts and hembing beads appear. However, melting is the area where you fall and reed. In this way, once the thickness of the base material (9j) and the welding current are determined, the relationship between the welding speed and the wire feed rate at which a stable bead can be formed is determined.On the other hand, the welding speed depends on the actual welding process. Considering that it should be set to an arbitrary value as much as possible, we will focus on the appropriate range of the wire feeding speed when the plate thickness of the base material (9) and the welding flow rate are determined.

Even if the heating distance of the wire changes due to operator hand shake, etc., the wire current is always controlled visually, so bead formation is performed stably and smoothly. Moreover, since the arc current is kept almost constant (10) by turning ON and OI'F of the switching element (14I), there is no change in the heat input to the base metal. Therefore, in a steady state, the heat input to the base metal and the surplus are Since the thickness is always constant, the bead shape is also uniform.
