る。In butt arc welding between carbon steel and dissimilar materials with different melting points, such as austenitic stainless steel or heat-resistant steel of nickel-based alloys such as Inconel, we Alternatively, when stacking weld beads in contact with the groove surface, the carbon steel base material is exposed directly under the arc, so the melting heat increases the penetration of the low-i carbon steel with a melting point, and the base metal components are supplied. #1 There was a risk that it would penetrate into the weld metal of the Australian material, causing cracks on the carbon steel side of the weld metal and deteriorating the corrosion resistance and mechanical properties of the weld metal. This is remarkable in the high-efficiency e@polar welding method in which the heat input of the welding arc is large and the penetration into the base metal is large.

ずしも満足しうるものではないなどの欠点があった。For this reason, in conventional Fi, welding material is welded to the groove side of the carbon steel base material in advance, the groove is processed after non-destructive inspection, and the mating base metal is butt welded with the same type of material, or When placing a bead along the groove on the carbon steel side, we use the AfII welding method with a low penetration rate, reducing the amount of arc heat for $1 under S* conditions! t, it was. However, these methods pose obstacles to increasing efficiency, increase work time, require the introduction of expensive welding equipment, and leave problems such as instability in the soundness of the resulting welded joints, making them not always satisfactory. It had some drawbacks, such as not being very durable.

を提供することを目的とする。The present invention was developed in view of the above-mentioned drawbacks, and it is possible to weld dissimilar materials with different melting points without cracking the weld metal even when welding them at 1W using a deep penetration m-pole type inert gas I welding method or submerged arc welding method. The object of the present invention is to provide a butt welding method that is fast and highly efficient.

行う。An embodiment of the present invention shown in the drawings will be described below. In the figure, the groove surface (
Im) and the groove surface (21) of the base material (2) on the higher melting point side such as stainless steel, after completing the groove alignment, welding material with the same or similar chemical composition as the electrode wire (3) and A 1-2 original thin metal plate (4) having mechanical properties is formed into the shape of a groove surface (groove surface + 1) and spot welded at appropriate intervals ( After bonding according to step 5), a melt electrode arc welding method is performed.

) is suppressed, and the transfer of components on the low melting point side from the base metal (1) to the weld metal (7) in the thin metal plate (4) is reduced. In addition, since welding is performed from above the thin metal plate (4), the thin metal plate (4) melts and the electrode wire (3)
The weld metal (7) forms a weld metal and can be welded at a high welding speed.

る−。As described above, according to the present invention, in butt welding of carbon steel and materials with different melting points such as stainless steel or heat-resistant steel, a thin metal plate that is the same as or of the same type as the welding material is used after the groove alignment of the butt weld joint. Arc welding is performed after welding to the groove surface on the low melting point material side, which eliminates excessive penetration of the low melting point material, prevents cracking of the deposited metal, and reduces the welding speed during welding. 6. The excellent effect of butt welding can be done with high efficiency.
