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,
