る。 If we look at the conventional general butt welding method of copper or copper alloy clad steel sheets in Figures 1 to 4, we can see that conventional butt welding of copper or copper alloy (hereinafter referred to as copper alloy) 02 is applied to the surface of carbon steel 01. When butt welding alloy clad steel plates, first, as shown in Fig. 1, a groove 03a is provided on the carbon steel 01 side, and a welding rod made of the same material as the carbon steel 01 is used to weld the welded part 03 in Fig. 2. After forming and welding the welded part 03 of carbon steel 01 without melting it to the copper alloy 02 side, as shown in FIG.
Welding part 04 of Monel (Ni-Cu alloy) is applied by biting into welding part 03 on the carbon steel 01 side from the side.
Next, as shown in FIG. 4, a welding part 05 is formed and finished on the Monel welding part 04 using a welding rod made of the same material as the copper alloy 02.

This sometimes caused weld cracking and deterioration of corrosion resistance of copper alloy clad steel sheets.

のである。 That is, the present invention involves butt welding or fillet welding of copper or copper alloy clad steel plates, which are made by cladding copper or copper alloy, particularly those having a wall thickness of 3 mm or less, on a carbon steel plate serving as a base material. In this case, build-up welding is performed on the copper or copper alloy surface of the groove (or weld line if there is no groove) using a copper or copper alloy welding rod to increase the wall thickness of the copper or copper alloy. This invention relates to a method for welding copper or copper alloy clad steel plates, which is characterized by carrying out ordinary welding.

材質上の組合せについて十分な注意を要する。 Note that it is generally better for the clad copper alloy and the copper alloy used for the welding rod to be the same material in terms of metallographic structure or corrosion resistance, but as will be described later, when welding phosphor bronze clad steel, aluminum bronze It is possible to use aluminum bronze welding rods for welding Cypronikel clad steel. However, it is not always possible to weld any combination of copper alloys, so when using welding rods made of clad copper alloys and different types of copper alloys, consider the material combinations. Requires sufficient caution.

て説明すると次の通りである。 In addition, in the method of the present invention, overlay welding is performed on the clad copper or copper alloy surface along the groove or weld line using a copper or copper alloy welding rod to increase the wall thickness of the copper or copper alloy part. After that, normal welding is performed, and the procedure for this normal welding will be explained as follows.

程を達成し得るものであればこれらの手順に限定
されることはない。 That is, along the above-mentioned build-up part, first weld from the carbon steel side with a carbon steel welding rod of the same material, then weld overlay Monel by biting into the carbon steel side from the copper or copper alloy side, and finally weld overlay. Either weld the same Monel with a copper or copper alloy welding rod, or first weld the Monel into the carbon steel side and weld overlay, then weld from the carbon steel side with a carbon steel welding rod, and finally weld the Monel with a copper or copper alloy welding rod. Procedures such as welding from the copper alloy side using a copper or copper alloy welding rod can be taken. Note that the method of the present invention is based on the premise of preventing penetration of the copper or copper alloy weld into the carbon steel side, so it is not limited to these procedures as long as it can achieve the above. .

て溶接を行なうのである。 In addition, as mentioned above, welding Monel by sandwiching it between molten carbon steel and molten copper or copper alloy is because when welding copper or copper alloy and carbon steel, the copper atoms As a result, the material becomes brittle (so-called solder embrittlement) because the particles gather at the grain boundaries of carbon steel. Welding is performed.

(In this case, the thickness is 3 mm) On the surface, a build-up welded part 6 (in this case, the thickness is about 2 mm) is formed by TIG welding of 9/1 Cypron-nickel. Next, as shown in FIG. 6, butt welding is performed on the groove on the carbon steel 1 side using a carbon steel welding rod of the same quality as the carbon steel 1 to form a welded portion 3. Then, as shown in Figure 7, 9/

It does not melt into the carbon steel 1 side, and therefore it is possible to achieve the effect that weld cracking or corrosion resistance deterioration due to dilution of iron does not occur.

に溶接される。 In Figure 9, the two phosphor bronze clad steel plates are beveled only on the carbon steel 1 side, and the phosphor bronze 7 (in this case, wall thickness is 2 mm) side is beveled along the weld line (in this case, the wall thickness is approximately 4 mm). (in this case, TIG welding is used to avoid melting the carbon steel 1 side.)
However, in Fig. 10, the carbon steel 1 side is the 6th
As in the case shown in the figure, a welded portion 3 is formed and welded using a carbon steel welding rod of the same quality as the carbon steel 1. Next, in FIG. 11, a groove 9 is formed on the phosphor bronze 7 side by gouging along the weld line so as to reach the weld part 3 of the carbon steel 1. Next, as shown in FIG. 12, a Monel weld 4 is placed on top of the carbon steel 1 weld 3.
As shown in FIG. 13, an aluminum-bronze weld 10 is finally placed over the Monel weld 4. The Monel welded portion 4 and the aluminum bronze welded portion 10 are welded so that the aluminum bronze overlay 8 that has been applied in advance is melted into the welded portion 4 and the aluminum bronze welded portion 10, respectively.
