408051 玉、發明說明（1) - 目前已知的接合兩異類金屬的方法主要分為加壓溶 接；以及非加壓熔接，即熔解及硬焊。而一般的熔焊指弧 溶接、氣熔接及火熔接數種方式。其應用原理為： 於弧熔接中，待熔接之金屬件（1)常藉電弧（11)端所 生之熱點，使得能完全熔解而互相熔合（如第一圖所示）。 於氡炔熔接或氣熔接中，藉點燃兩種混合氣體（通常 為氧及乙炔），而產生一高溫火燄。 電阻溶接係一加熱及加壓熔接方法，待溶接之工件， 於接合點通以大量電流，使升達熔解溫度，再藉機械壓力 予以壓合。 上述各種傳統接合方法如氧炔熔接方式需藉由助烊劑 或媒介予以結合，因此結合後之應力強度、封熱性、導電 性等遂大大的受到影響；而如弧熔接、電阻熔接之加熱加 ®燦接方式雖沒有應用助焊劑，但同樣會破壞兩接合金屬 壓合處的組織結晶分子，使該壓合處金屬材料之機械性質 大為降低，同時虎除性增加· 本發明使用完全不同的焊接原理，克服傳统焊接方式 的種種缺失’可提供一種特別適合於鐵舆非鐵金屬之接合 應用上，具有簡易加工、加工成本低廉’卻可獲得高結合 度、傳導性、耐熱性佳且後製加工性優良之結合材料。 為使諸審査委貝得以進一步瞭解本發明之應用技術原 理，茲配合簡單圈式說明如后： 圓式說明：408051 Jade and invention description (1)-The currently known methods for joining two dissimilar metals are mainly divided into pressure welding; and non-pressure welding, that is, melting and brazing. The general welding means arc welding, gas welding and fire welding. The application principle is as follows: In arc welding, the metal parts (1) to be welded often take advantage of the hot spots generated at the arc (11) end, so that they can be completely melted and fused with each other (as shown in the first figure). In acetylene welding or gas welding, a high-temperature flame is generated by igniting two mixed gases (usually oxygen and acetylene). Resistance welding is a heating and pressure welding method. A large amount of current is passed through the joint to the welding point to reach the melting temperature, and then it is pressed by mechanical pressure. The above-mentioned various conventional joining methods such as oxy-acetylene welding need to be combined by using an adjuvant or a medium, so the stress intensity, heat sealing, and electrical conductivity after the joining are greatly affected; while heating such as arc welding and resistance welding ® Although the welding method is not used, the same will damage the crystallized molecules of the joint of the two joints, which will greatly reduce the mechanical properties of the metal material at the joint and increase the resistance. The use of the present invention is completely different. Welding principle to overcome the lack of traditional welding methods 'can provide a particularly suitable for iron and non-ferrous metal bonding applications, with simple processing, low processing cost' but can obtain high bonding, conductivity, good heat resistance and Bonding material with excellent post-processability. In order to enable the review committees to further understand the principles of the application technology of the present invention, the simple circle description is as follows:

Explanation of the invention (3) Thickness of heterogeneous metals such as phosphor bronze (3) (filler) are closely positioned, and the heater of the heater (5) is set on the phosphor metal bronze (3) At a short distance on the other side, heat it appropriately and proceed slowly according to the welding direction. Step b. Another inert gas vessel supplier (6) 'with a wide opening is provided and its inert gas outlet (61) is located behind the processing line of the heater (5) to slowly supply a fixed speed and an appropriate amount of inert gas (62). . Step c. On the bonding surface (4) of two dissimilar metals such as iron-based (2) and phosphor bronze (3), when heated to a proper temperature, the phosphor bronze (3) with a lower melting point will first melt, and the heat is just The metal plane bismuth crystal molecules of the bonding surface (4) (such as the interface between iron-based (2) and phosphor bronze (3)) can be deformed to produce magnetic effect phase adhesion and bonding. Among them, the width of the heater (5) and the welding speed in step a should be adjusted in accordance with the power of the heater (5) and the magnetic effect characteristics of the heated metal. Also, 'the traveling speed of the inert gas radon supplier (6) should be synchronized with the heater (5)' and the blowing speed of the supply of inert gas (62) should be controlled in the molten pool just after the heater (5) is heated. (51) the surrounding air (especially oxygen), and provide continuous blowing of inert gas (62); however, the supply flow rate of inert gas (62) should not be too fast to cause air turbulence, causing the original covering in the molten pool (51 ) The outside inert gas (62) is blown away, so that the oxygen enters the molten pool (51), which causes the molten pool (51) to oxidize and destroy the structure of the welded metal (race). The ideal shape of the inert gas skull supply (6) should be a team shape with three openings, and the air hole (63) is preferably a round hole. In the present invention, a large area of thick metal to be welded is welded. During processing,
