Study of end cracking during one-sided submerged arc welding with flux-copper backing WANG Xing Chun1, 2, a, LU Feng Gui1, b *, ANDERSEN Isak2, c and YU Long Seng3, d 1School of Materials Science and Engineering, Shanghai Jiao Tong University (SJTU), 800 Dongchuan Road, Minhang District, Shanghai 200240, P.R.
Noted that HSC for the given materials were far less than 4 which meant the given materials were immune to hot cracking, or nearly so [9].
Noted that carbon contents for the given materials in Table 1 are not more than peritectic point (WC = 0.16 %) refer to Fe-C phase diagram.
The calculated Mn/S ratio for the given materials were in the range of 118 to 266 listed in Table 1, which indicated also the material grade is immune to solidification cracking, or nearly so [9, 13].
Welding residual stress caused by thermal stress which finally leads to compressive stress on the surface area whilst tensile stress existing in the core part of materials.

There were else taken two piece of fragments, there was a visible boundary on it, indicating that it had two materials; individually drilling on two materials to take two iron chipings to test chemical compositions of the two materials; with metallographic grinding wheel cutting machine along the longitudinal direction, some specimens were cut with both section parallel, the specimen thickness of 10 mm circumferential and radial height of 78 mm, after flat finishing, from the roll surface at the radial was its Rockwell hardness measured on the section; then having hot acid etched to take a macroscopic test; on macroscopic specimen there was a visible light interface which divided the specimen into two layer materials, from the roll surface to the interface of the outer material, thickness of about 52mm, with A, B respectively indicating said the outer layer near the roll surface zone and interface zone; below interface the inner layer material C zone(see Figure 2); the metallographic polished
Fig.3 Smooth rupture zone Fig.4 Smooth sector Figure 5 circumferential crack on the roll cross section on the roll boundary layer in the back-up roll barrel Chemical Composition.The chemical composition test results of outer and inner materials of the roll barrel fragments and the chemical compositions described in the material category of "high chrome centrifugal compound Ⅱ" and "pearlitic spheroidal graphite Ⅰ" of the China National Standard GB / T 1504-2008 "Cast Iron Roll" were shown in Table 1.
The high Cr content of inner material might be due to the chromium diffusion of outer layer material.

According to the phenomenon, in process of injecting artificial-interlayer, because pressure drop occurs around well bore and material balance relationship of reservoir, so interlayer is injected, oil-interlayer interface becomes deformed and presents a downward bend shape.
