面積のクラツド鋼材を能率よく且つ安価に製造できるこ
とから最も広く利用されている。Clad steel materials are generally manufactured by the explosion bonding method, overlay method, roll rolling method, etc. Among these methods, the roll rolling method is the most widely used because it can produce large area clad steel materials efficiently and at low cost. There is.

接が用いられている。In the roll rolling method, a clad slab to be subjected to rolling is assembled by cleaning the joint surfaces of dissimilar metal materials, overlapping them, and seal-welding the joint surfaces without exposing the joint surfaces to the atmosphere. The seal welding in assembling this clad slab is generally arc welding such as shielded arc welding or gas shield welding, or electron beam welding.

溶接して組み立てらる。Specifically, the former method of assembling a clad slab using arc welding involves layering dissimilar metal materials in the atmosphere, attaching a deaeration pipe to a part of the joint surface, and sealing the periphery of the joint surface by arc welding. On the other hand, in the method of assembling clad slabs by electron beam welding, dissimilar metal materials are layered in a vacuum chamber, the chamber is evacuated, and then the periphery of the joint surfaces is electron beam welded. It can be assembled.

理に時間を要し、又溶接速度も遅いことからクラッドス
ラブの組み立てに長時間を要するという欠点がある。(Problem to be solved by the invention) By the way, the method of assembling a clad slab by arc welding has the advantage of being highly versatile as it does not require special equipment or jigs. Moreover, since the degassing process takes time and the welding speed is slow, it takes a long time to assemble the clad slab.

ることがある。On the other hand, the method of assembling craft slabs using electron beam welding has the advantage that it is not necessary to attach a degassing vibrator, and furthermore, the degassing process can be carried out easily, making it possible to assemble clad slabs in a short time. There is. However, on the other hand, the weld metal width in electron beam welding is 3 to 1
Because it is narrow (0 m5), it is difficult to follow the welding pattern, and in some cases, a weld bead with a short penetration depth may occur, and the weld may break because it cannot sufficiently withstand the shear force during rolling.
通常、クランドスラブの組み立てに際しては、金属材料
の接合面の平坦度は厳しく管理されてはいるものの、接
合面全体を均一に平坦とすることは極めて困難である。Normally, when assembling a ground slab, although the flatness of the joint surfaces of metal materials is strictly controlled, it is extremely difficult to make the entire joint surface uniformly flat.
このため異種金属材料を重ね合わせたとき、その接合面
の位置は全周縁において必ずしも同一高さとならず微妙

１９２号公報）。One method to overcome these drawbacks of clad slabs assembled by electron beam welding is to weld the clad slabs by electron beam welding while supplying filler wire, band-shaped, or rod-shaped filler metal from the rear in the welding direction. A method of assembling and rolling has been proposed (Japanese Patent Laid-Open No. 61-226
Publication No. 192).

立てることができる方法を提供することにある。The aim of Zero Hat and Mei is to avoid using such filler metals (even if there is a welded part with insufficient penetration at the periphery of the joint surface seal-welded by electron beam welding, it will not break during rolling. The purpose of the present invention is to provide a method for relatively efficiently assembling clad slabs that require no additional work.

、本発明を完成した。(Means for Solving the Problems) The present inventors have conducted various studies on methods for solving the problem of clad slab breakage during rolling caused by insufficient penetration in electron beam welding, and as a result, the joint surface The present invention was completed based on the discovery that by seal-welding the periphery using electron beam welding and then arc welding, it is possible to relatively efficiently assemble a craft slab in which the welded portion does not break during rolling.

の組み立て方法にある。The gist of the present invention is to provide a method for assembling a clad slab by overlapping dissimilar materials and seal-welding the periphery of the joint surfaces without the presence of atmosphere at the joint surfaces of the overlapping materials. The method for assembling a clad slab is characterized in that after electron beam welding the peripheral edge of the surface, arc welding is further performed on the edge of the electron beam weld.

らである。In the present invention, the reason why the periphery of the joint surface is first sealed by electron beam welding is that electron beam welding does not require the installation of a degassing pipe unlike the assembly of clad slabs by arc welding, and the degassing process Because it is easy to perform and the welding speed is fast,
This is because the clad slab can be sealed in a short time.

。As shown in Figure 4, arc welding is a process in which welding occurs when the weld bead (3) is deviated from its normal position due to improper tracing during electron beam welding. The main purpose is to compensate for the lack of welding strength due to insufficient penetration. Therefore, these electron beam welding bead parts (3) and arc welding bead parts (
