    Abstract: A pressure vessel with corrosion resistant lining and inexpensive overall is constructed in two steps. First, a thinwalled vessel is prepared from integrally clad plate by conventional means, the cladding thus being of controlled quality, thickness and well bonded to the backing metal. Then the thickness of the backing metal is built up to the desired dimension preferably by electroslag deposition in the continuous casting process. The electroslag layer bonds to the backing layer without penetrating to the inner layer, and thus preserves the corrosion resistance of the lining. Heavy tube sheets are prepared in similar manner by depositing additional backing metal behind a clad metal plate. We also have the possibility of using the side of the original clad sheet which is mild or low alloy wrought steel to make a mold or part of a mold against which the electroslag weld deposit is formed, such as by standing up the wrought clad sheets with the corrosion resisting layer outward and the wrought mild or low alloy steel layer facing inward to bond with the electroslag weld layer.

    Abstract translation: 具有耐腐蚀衬里和廉价整体的压力容器分两步构成。 首先，通过常规方式由整体复合板制备薄壁容器，因此包层具有可控的质量，厚度和良好地结合到背衬金属。 然后，优选通过连续铸造工艺中的电渣沉积，将背衬金属的厚度建立到所需尺寸。 电渣层与背层结合，不会渗入内层，从而保持衬里的耐腐蚀性。 通过在复合金属板后面沉积额外的背衬金属，以相似的方式制备重的管板。 也可以使用作为温和或低合金锻造的原始复合板的一面来制造模具或形成电渣焊接沉积物的模具的一部分，例如通过将锻造的包覆板与 耐腐蚀层向外，并且锻造的温和或低合金钢层面向内与电渣焊接层接合。
