本発明はアーク溶接機に係シ、特に溶接しようとする部

It's about machines.

めの矯正ローラである。As shown in FIG. 3, in a conventional arc welding machine, a welding wire 6, which is a consumable electrode, protrudes from a power supply tip 4 of a welding torch 2, and the welding wire 6 and the workpiece are welded oppositely. Power is supplied to a certain base metal 8 from the welding power source 10 via the power cables 12 (12A, 12B), and arc 140 generation is maintained between the welding wire 6 and the base metal 8, thereby welding along the seam 8A. and one dot 9 are formed. The welding wire 6 is wound around a wire reel 16 and passed through a conduit cable 18 to be held such that its tip protrudes from the power supply tip 4 of the welding torch 2. Note that the reference numeral 20 is a feeding roller for feeding out the welding wire 6, and the reference numeral 22 is a correction roller for keeping the welding wire 6A protruding from the power feeding tip 4 in a straight state.

ワイヤの巻き出し当初と巻き出し終り近くとでは矯正ロ
ー２２２ヘ供給される溶接ワイヤの曲率がかなり異なる
ため、矯正ローラ２２による調整量が自づから異なり、
これを考慮した調整を行ねばならなかった。In the conventional arc welding machine described above, the straightness of the protruding wire 6A protruding from the power supply tip 4 changes greatly due to a slight curvature adjustment by the correction roller 22, so accurate adjustment is required using a correction roller consisting of a plurality of roller groups. It was said that In particular, since the curvature of the welding wire supplied to the straightening row 222 differs considerably between the beginning of unwinding and near the end of the unwinding of the wire unwound from the wire reel 16, the amount of adjustment by the straightening roller 22 naturally differs.
We had to make adjustments to take this into consideration.

材８の継目８Ａに一致せず、正確な溶接ができないとい
う問題点があった。Even if the curvature of the welding wire 60 is adjusted using the straightening row 222, the conduit cable 18 is often used in a bent state, and the welding wire 6 is deformed by being inserted into the conduit cable 18. The welding wire protruding from the power supply tip 4 is bent due to the deformation received from the conduit cable 18, and as shown in FIG. However, there was a problem that accurate welding could not be performed.

があった。Furthermore, even if an attempt is made to increase the amount of wire protrusion (W, L,) in order to increase the melting speed of the welding wire 6, the amount of misalignment between the tip of the welding wire and the seam 8A will increase accordingly. In other words, there was a natural limit to welding speed.
本発明は前記従来技術の問題点に鑑みなされたもので、

接ワイヤを常に真直ぐな状態で突出保持することの可能
なアーク溶接機を提供することにある。The present invention has been made in view of the problems of the prior art,
The purpose is to provide an arc welding machine that can always maintain a straight welding wire protruding toward a part to be welded.

とする部位に突出させた構造のアーク溶接機において、
前記溶接ワイヤは、所定温度以上となったときに真直ぐ
な形状となる形状記憶処理の施されていることを特徴と
するものである。An arc welding machine according to the present invention has a structure in which a welding wire protrudes from a part to be welded, and includes:
The welding wire is characterized by being subjected to shape memory treatment so that it assumes a straight shape when the temperature reaches a predetermined temperature or higher.
溶接しようとする部位に向けて突出する溶接ワイヤヲエ

状態となる。そのため溶接ワイヤの先端を母材の継目に
臨む位置に保持することが容易で、溶接ワイヤの先端は
母材の継目から大きく外れることがない。The welding wire that protrudes toward the part to be welded is heated by the arc heat and regenerated into a straight shape stored in advance. Therefore, during welding work, the welding wire is always kept straight within the area affected by the arc heat. Therefore, it is easy to hold the tip of the welding wire in a position facing the seam of the base metal, and the tip of the welding wire does not come off significantly from the seam of the base metal.
次に本発明の実施例を図面に基づいて説明する。 Next, embodiments of the present invention will be described based on the drawings.

られるようになっている。Figure 1 shows an arc welding machine that uses welding wire as a consumable electrode.
The welding wire 26 wound around the welding wire 26 is inserted into the conduit cable 18 and led to the welding torch 2, and the tip thereof protrudes from the power supply tip 4 to a feed roll 20 provided in the middle of the wire feed path. The data is sent at a predetermined speed.

The alloy wire is wound around the wire reel 16 at a temperature lower than the degree by which the alloy wire is subjected to a shape memory treatment so that it becomes straight when the temperature reaches the transformation temperature (400° C.) or higher.

による発熱抵抗によって充分加熱されてＦｅ −２７Ｎ
ｉ −０，４Ｃ合金の変態温度以上となっている。As shown in FIG. 2, the tip of the welding torch 2 has a structure in which a welding wire 26 protrudes from a power supply tip 4, and a shielding gas as shown by arrow A is supplied to the outer periphery of the power supply tip 4. A gas nozzle 30 is formed for this purpose. As shown in FIG. 2, the tip portion 4A of the power supply tip 4 is formed at a position retracted inward from the lower end portion 30A of the gas nozzle 30, and has a wire extension and a wire protrusion fi (w, I, , ) are set larger than K in the conventional ones (see Figure 4), and the welding wire 26 protruding towards the seam 8AK of the base metal 8 is sufficiently heated by the heating resistance caused by the arc current and becomes Fe -27N.
It is higher than the transformation temperature of i-0,4C alloy.

直ぐな形状に再生され、給電チップ４を出た溶接ワイヤ
突出部２６Ａは真直ぐな状態となってその先端は母材８
の継目８Ａに常に一致した状態となる。In this way, the welding wire 26 becomes Fe-2 due to the resistance heat generation within the power supply tip 4 and the heat transferred from the power supply tip 4.
The welding wire protrusion 26A that exits the power supply tip 4 is heated to a temperature higher than the transformation temperature of the 7Ni-0,4C alloy and regenerated into a straight shape, and the welding wire protrusion 26A that exits the power supply tip 4 is in a straight state and its tip is connected to the base material 8.
It will always be in a state where it coincides with the seam 8A.
本実施例によれば次のような効果が得られる。According to this embodiment, the following effects can be obtained.
■ 給電チップ４から突出する溶接ワイヤ突出部２６Ａ

真上に位置させることができ、これによって信頼性の高
い溶接が可能となる。■ Welding wire protrusion 26A protruding from power supply tip 4
can be kept straight at all times, so if the welding torch 2 is accurately positioned with respect to the seam 8A, the tip of the welding wire protrusion 26A can always be positioned directly above the seam 8A, This enables highly reliable welding.
■ 溶接ワイヤを溶接トーチ２に送給するワイヤ送給路

微調整を行なう必要がなく、それだけ調整作業も容易と
なる。■ Since a straightening roll (see Figure 3) is not installed on the wire feed path that feeds the welding wire to the welding torch 2,
The number of work steps is correspondingly reduced and the length of the wire feeding path can be shortened. Note that even if a straightening roll is installed in the middle of the wire feeding path, the straightening roll is not used to straighten the bend in the wire protrusion 26A, but only for smooth feeding of the welding wire 26 within the conduit cable 18. Therefore, there is no need to perform precise and complicated roll fine adjustment, and the adjustment work becomes easier.
■ コンジットケープρ１８を複雑な形状に配設したと
しても溶接ワイヤ突出部２６Ａは常に真直ぐな状態とな
るので、コンジットケーブル１８の配役形状における制
約が大幅に緩和される。(2) Even if the conduit cape ρ18 is arranged in a complicated shape, the welding wire protrusion 26A is always in a straight state, so the restrictions on the arrangement shape of the conduit cable 18 are greatly relaxed.
■ ワイヤ突出量（Ｗ、Ｌ、）が大きいので、太きな溶
融量を確保でき、それによって溶接ワイヤ２６の溶融速
度が増大し溶接能率が飛躍的に向上する。(2) Since the wire protrusion amount (W, L,) is large, a large amount of melting can be ensured, thereby increasing the melting speed of the welding wire 26 and dramatically improving welding efficiency.
さらに溶接スパッタの給電チップ４への付着が少なくな
シ、給電チップ４の交換頻度が少なくなる。Furthermore, since welding spatter is less likely to adhere to the power supply tip 4, the frequency of replacing the power supply tip 4 is reduced.
■ 給電チップ４はシールドガスを噴出するノズル３０
の先端部よりも内方に位置するので、ノズル３０から噴
出されるシールドガスの流れがととのい、ブローホール
などの溶接欠陥の発生が抑制される。■ The power supply chip 4 has a nozzle 30 that spouts shielding gas.
Since the shielding gas is located inward from the tip of the nozzle 30, the flow of the shielding gas ejected from the nozzle 30 is smooth, and the occurrence of welding defects such as blowholes is suppressed.
