。In addition, the part of the rotating plate called the base plate is made of tool steel (SK).
It is made of special steel such as heat-resistant tool steel, such as steel, Or-Mo steel (SOM), and Flutenside stainless steel.
そして従来の製造法は、この刃先チップ（２）と基板（
１）との接合を、銅ろう付は等のろう付は法などで接合
しているものが多い。In the conventional manufacturing method, this cutting edge tip (2) and the substrate (
In many cases, the connection with 1) is performed using methods such as copper brazing.

を行なうものである。The method is to heat the joint between the cutting edge tip (2) and the substrate (1) using high-frequency waves or a burner heating method to a predetermined temperature, then add a brazing material and perform brazing. It is something.

していた。According to the conventional brazing method, the substrate (1) and the cutting edge tip (2) are bonded together at a temperature that is generally 600℃~
It is necessary to heat up to 1100°C, and the heating range is wide, and not only does it take longer to heat up, but the hardness of the tempered substrate (1) can be reduced by heating it to a temperature of 1100°C. However, there were problems such as a decrease in energy consumption.

、耐熱強度が低いろう材が加熱されて強度が低下する接
合部より剥れるなどの問題点も合わせ有していた。In addition, this type of brazing can also be applied to the cutting edge tip (
2) is caused by the frictional heat generated between the saw blade and the workpiece, such as concrete, that occurs when cutting concrete, etc., which causes the brazing filler metal, which has a low melting point and low heat resistance strength, to heat up and peel off from the joint where the strength decreases. It also had some problems.

属が精練されるようにして溶接するものである。In the fusion welding method using a high-density energy beam according to the present invention, when performing fusion welding using a high-density beam with heat-resistant strength, when butt welding only the sintered metal chips to be joined, such as the substrate and the cutting edge tip, it is difficult to join the bond part. In order to compensate for the drawback of reduced strength, nickel plating is applied in advance at least near the welding area of the board to improve the composition of the molten metal during welding, and the beam irradiation is applied to the sintered alloy tip. In addition, welding is performed in such a way that the molten metal is sufficiently refined.

質化し、ブローアウトもない。Since the nickel component plated in the molten metal is melted, weld cracking is prevented, and the fusion between the substrate and the sintered alloy chip is good, and the nickel component plated in the molten metal is melted. Therefore, the thermal influence on the sintered alloy chip is reduced, and furthermore, the molten metal pool is sufficiently refined, so the molten metal, that is, the welded part, is homogenized and there is no blowout.

ダイヤモンド粒などが混入される。Tempered steel is generally used for the base plate (1) of saw blades for cutting concrete, but this material has lubricants to maintain heat resistance and elastic strength when cutting workpieces such as concrete IJ. This, tool steel (EIK) material, C! r-MO steel (SO
M) materials, high carbon steels such as martensitic stainless steel materials, and special steels such as high chromium steels are used.On the other hand, for the sintered alloy tips, for example, the cutting edge tips (2), in order to improve the cutting properties of concrete, A hard sintered alloy such as tungsten carbide is used, and artificial diamond particles are mixed in to improve machinability.
しかるに、これらの基板（１）と刃先チップ（２）とは
、共Ｉこ溶接性が悪く、従来はろう付は法で接合されて
いたものである。However, both the substrate (1) and the cutting edge tip (2) have poor weldability and have conventionally been joined by brazing.

ギービームを用い、できるだけ溶融部を少なくする溶接
法が望ましい。これは溶融部が多くなればそれだけ炭素
など低融点成分の析出、結晶化が進み、溶接割れの原因
となるからである。If this is to be welded by a fusion welding method, it is desirable to use a high-density energy beam such as an electron beam or a laser beam to minimize the number of fused parts. This is because the more molten parts there are, the more the precipitation and crystallization of low melting point components such as carbon progresses, causing weld cracking.
また、刃先チップ（２）の材質は焼結合金材であり、ビ
ームを刃先チップ（２）に直接照射すると、含有ガスに
よるブローアウト、急熱、急冷による脆弱化などが起こ
るために避けなくてはならない。In addition, the material of the cutting edge tip (2) is a sintered alloy material, and direct irradiation of the beam to the cutting edge tip (2) must be avoided because blowout due to contained gas, rapid heating, and embrittlement due to rapid cooling will occur. Must not be.
また、一方、高密度エネルギービームによるビード幅の
狭い溶接では、溶接後の溶融部の急冷につながり、従っ
て、焼入現象を伴なって、ボンド部の割れにつながる。On the other hand, welding with a narrow bead width using a high-density energy beam leads to rapid cooling of the molten part after welding, which is accompanied by a quenching phenomenon, leading to cracking of the bond part.

先チップ（２）との融合をも助けるようにさせている。Therefore, it is recommended to apply nickel plating of approximately 20/1 m or more to at least the vicinity of the welding part of the substrate (1) in advance, and increase the nickel component ratio by mixing the plated nickel into the molten metal during beam irradiation. This not only eases hardenability during cooling, but also facilitates fusion with the cutting edge tip (2), which is a sintered alloy.
次にビームの照射位置と、照射角度およびビームのオシ
レーション効果について述べる。Next, we will discuss the beam irradiation position, irradiation angle, and beam oscillation effect.
ビーム照射位置は、必ず基板（１）側へオフセットさせ
てビームが直接刃先チップ（２）に当たらないよう配慮
する。この場合のオフセット量（１５）は溶接後の表面
ビード幅の約半分弱が理想で、ビームの種類、基板の厚
さ、溶接速度等によって異なるが、一般的には０．１〜
０．５ｍｍの範囲である。Be sure to offset the beam irradiation position toward the substrate (1) so that the beam does not directly hit the cutting edge tip (2). The offset amount (15) in this case is ideally about a little less than half of the surface bead width after welding, and although it varies depending on the type of beam, substrate thickness, welding speed, etc., it is generally 0.1~
The range is 0.5 mm.
次にビームの照射角度（１６）は、基板（１）に対し垂
直な角度より基板側へ１°〜５°傾ける。これは溶接ビ

ようにするためで、刃先チップ（２）に対する熱影響の
加不足を無くするためである。Next, the beam irradiation angle (16) is tilted 1° to 5° toward the substrate from the angle perpendicular to the substrate (1). This is because the cross-sectional shape of the weld bead is wider on the front side and narrower on the back side.
This is to ensure that the apex of the cutting edge tip is parallel to the joining end surface of the cutting edge tip, and to eliminate the excess or lack of thermal influence on the cutting edge tip (2).
また、第３図に示すように、ビームを溶接方向き同方向

り［／−ターの発生を防ぐためである。In addition, as shown in Fig. 3, the beam is aligned in the same direction as the welding direction with a width of ±0.1 to ±o and a width of 60 to 2000 s aI++.
When oscillating at Hz, the components in the molten metal are homogenized, the blowout caused by contained gases and impurities is separated from the molten metal, and by promoting this, large cavities in the bond part or the bead surface are This is to prevent the occurrence of a large gap.
以上述べたように、ニッケルメッキ、ビームオフセット

果により、より一層良好な溶接結果をもたらす。As mentioned above, by using nickel plating, beam offset, beam tilt, and beam oscillation,
The synergistic effect of adding nickel, not applying the beam to the cutting edge tip, and scouring the molten metal pool leads to even better welding results.
また、ニッケルメッキの代わりに、ニッケル薄を基板（

その場合も上記実施例と同様の効果をもたらす。しかし
、メツキに比べて、作業性の面で劣るために、実験段階

産には向かない。Also, instead of nickel plating, thin nickel is used on the substrate (
It may be inserted between 1) and the cutting edge tip (2),
In that case as well, the same effects as in the above embodiment are brought about. However, since it is inferior in terms of workability compared to metal cutting, although it is an effective means for sample testing at the experimental stage, it is not suitable for mass production.
更番こ、基板（１）に対するビーム（１３）の照射角度

例と同じである。The irradiation angle of the beam (13) with respect to the substrate (1) has been explained by the inclination of the beam (13), but conversely, by fixing the beam (13), the angle of irradiation of the beam (13) with respect to the substrate (1) and the cutting tip (
2) may be tilted (not shown), and the effect is the same as in the above embodiment.

法が得られる効果を有している。As described above, according to the present invention, by combining nickel plating on the substrate in advance and irradiation by tilting and oscillating the beam, it is possible to melt weld difficult-to-weld materials, and it is possible to It is possible to improve workability compared to the method of sandwiching the board, and in contrast to the conventional brazing method, it prevents the hardness from decreasing due to a wide range of temperature rise of the board and increases the heat resistance strength. This has the effect of providing a fusion welding method using a high-density energy beam that can improve the reliability of fusion welding between the substrate and the sintered alloy chip.
