て銀ろう付けによってなされているが、いずれも極めて
困莫ＩＦな接合で以下のような欠点があった。Conventionally, galvanized steel sheets are joined together mainly by resistance welding or caulking, and joined to copper alloy parts mainly by silver brazing, but both methods are extremely difficult to connect and have the following drawbacks. Ta.
（１）抵抗溶接には比較的高電流と高温を要し能力の大
きい溶接機が必要であり電極先端の消耗がはげしい。(1) Resistance welding requires relatively high current and high temperature, requires a welding machine with high capacity, and the electrode tip is subject to rapid wear.
（２）かしめは接合の安定性と融通性、耐もれ性に欠け

（３１＆Ｈろう付けはろう代が高価で且つ手作業のため
工数を要し、特にフラックス除去に多大の工数を要して
接合部が高い。(31&H brazing requires an expensive brazing cost and requires a lot of man-hours because it is manual work. In particular, it requires a lot of man-hours to remove flux, making the joints expensive.

所を圧接接合する。The feature of the present invention is that a Cu--Zn alloy molten phase is produced by contact heating the zinc and copper coated on a galvanized steel sheet, and this is used as a brazing material to join the two. When joining galvanized steel sheets, a copper foil is sandwiched between the points to be joined, and electricity is applied and pressure is applied using upper and lower electrodes with iron-based heating plates attached to the tips. CLI-Zn alloy is formed by heat conduction from the heating plates and resistance heating. A molten phase is generated and the parts are pressure-welded.

５０ Ｋｙ程度が適当である。Figure 2 shows an example of joining a copper alloy part to a galvanized steel plate, in which a hole is made in the galvanized steel plate 1, a flanged copper pipe 3 is fitted into the hole, and the lower surface of the flange of the copper pipe and the galvanized steel plate are brought into direct contact. The figure shows the situation where heating plate 4 is attached to a part of the flange of the copper pipe with electrode 6 holding down the 2 side, and galvanized steel plate is being heated by holding down the zinc steel plate with lower electrode 7 to which heating plate 5 is attached. It is. On the contact surface of the art material, the zinc and copper of the coated galvanized steel sheet react with each other when energized, forming a C11-Zn alloy phase similar to the example shown in Figure 1, and this is then separated between the galvanized steel sheet and the copper pipe. , it is completely joined without brazing filler metal or flux. When the galvanized steel plate is 1°Qt, the copper pipe has an outer diameter of 12.7φ, and a wall thickness of 0.8t, the resistance heating conditions are: current 10.0OOA, energization time 120, and pressure 3.
Approximately 50 Ky is appropriate.
尚、電極先端に発熱板を使用することにより。In addition, by using a heating plate at the tip of the electrode.
亜鉛鋼板溶接上の欠点である銅電極の消耗の問題がなく
、高抵抗材のため比較的低電流で高熱が得られる特徴が
生かされる。加熱板のない場合は、銅が極めて電気伝導
度が高いため熱の集中が悪く電流をあげても所要の温度
が得られないことが多い。There is no problem of copper electrode wear, which is a drawback in welding galvanized steel sheets, and since it is a high-resistance material, it takes advantage of the ability to generate high heat with a relatively low current. If there is no heating plate, copper has extremely high electrical conductivity, so heat concentration is poor, and the required temperature is often not achieved even if the current is increased.
