摘要： An intermetallic bond between a ferrous metal and a non-ferrous metal wherein an intermetallic bond layer that is substantially free of graphic inclusions joins the two. The graphite is effectively eliminated from the bond layer by either removing it from the ferrous metal or by sealing it off from the bond layer. Graphite removal may be accomplished in a variety of ways, including electrochemical cleaning and laser surface treatment. Alternatively, the graphite may be prevented from incursing into the bond region by sealing it off with a layer of metal, such as a chromium plating, that prevents it from penetrating through the bond layer and into the non-ferrous metal.

摘要： A method and apparatus for welding together two members such as relatively thick metallic plates. The plates are positioned vertically in the same plane and are spaced apart by a gap which is equal to the desired width of the seam or joint. A moving current of molten metal is caused to flow horizontally through the gap, starting at the bottom of the gap, until the plates are heated to a welding temperature, and then the flow is ceased to allow for weld solidification. For welding plates when the length of the weld is greater than the depth of the molten metal stream, the plates are moved downwardly simultaneously while continuing the flow of molten metal through the gap. The plates are moved at a rate which will allow for solidification of the weld metal until the gap is filled.
摘要翻译：一种用于将两个构件如相对厚的金属板焊接在一起的方法和装置。板垂直地定位在同一平面中，并且间隔开等于接缝或接缝的期望宽度的间隙。使熔融金属的移动电流从间隙的底部水平地流过间隙，直到板被加热到焊接温度，然后停止流动以允许焊接凝固。对于焊接板的长度大于熔融金属流的深度时，焊接板同时向下移动，同时使熔融金属流过间隙。以允许焊接金属固化的速率移动板直到间隙被填充。

摘要： A method of welding together two members placed with the edge surfaces to be joined in mutually facing relationship and separated by a weld gap. A weld material is endothermically heated to a molten state and flowed through the weld gap for heating the members to cause melting of the edge surfaces with the weld metal flow being continued for a time sufficient to provide a ratio of weld gap metal to total metal flowed of at least 1:50, and then the flow is terminated to provide for weld solidification.
