摘要： A welding method uses a high energy density radiation beam such as an electron beam or preferably a substantially continuous wave laser beam (48) to weld a pair of sheets (40, 42) using an oblong focused beam spot (50). The radiation beam source (56) has a power of at least one kilowatt. A beam delivery system (46) capable of focusing the beam into a generally rectangular oblong spot shape directs the oblong beam spot onto at least one of the sheets to weld them together, with the longitudinal axis of the beam spot preferably oriented tangent to the weld line (60). Deep penetration keyhole welds (54) are produced.

摘要： A method of lap welding for producing a welded lap joint (110) having good integrity, high peel strength, high tensile strength, high fatigue resistance, where the overlapped sheets (30, 32) are fused together across their region of overlap (50). Before welding, one sheet (30) is overlapped with another sheet (32) forming a lap joint (94). Preferably, the width of overlap is at least 50 % of the thickness of the thinnest sheet and no greater than twice the thickness of the thickest sheet. During welding, a high energy density radiation beam (34) is trained on at least one of the sheets and is acutely angled relative to the plane of overlap (56), which coincides with the weld interface (48) of the sheets (30, 32). Preferably, the sheets (30, 32) can be oriented relative to the direction of gravity such that the plane of overlap (56) of the sheets (30, 32) is acutely oriented relative to gravity so that during welding the direction of gravity influences formation, geometry and flow of a molten weld nugget (102). To join the sheets (30, 32), the beam (34) is trained on at least one of the sheets for a sufficient period of time and with a sufficient energy density to weld the sheets (30, 32) together completely from front to back of the overlap (56) producing a weld (110) having high peel strength with no unfused lip across the overlapping area. After welding is completed, the sheets (30, 32) can be formed using any conventional forming or any shaping process.
摘要翻译：一种搭接焊接方法，用于制造具有良好的完整性，高剥离强度，高拉伸强度，高耐疲劳性的焊接搭接接头（110），其中重叠片材（30,32）在其重叠区域（50）处熔合在一起，。在焊接之前，一片（30）与形成搭接部（94）的另一片（32）重叠。优选地，重叠的宽度是最薄片材的厚度的至少50％，不大于最厚片材厚度的两倍。在焊接期间，在至少一个片材上训练高能量密度辐射束（34），并且相对于重叠平面（56）具有锐角，其与片材（30,30）的焊接界面（48）重合， 32）。优选地，片材（30,32）可以相对于重力方向定向，使得片材（30,32）的重叠平面（56）相对于重力是锐利取向的，使得在焊接期间重力影响熔融焊点（102）的形成，几何形状和流动。为了接合片材（30,32），将梁（34）在至少一个片材上训练足够的时间并具有足够的能量密度以将片材（30,32）从前面完全地焊接到（56）的后部产生具有高剥离强度的焊缝（110），并且在重叠区域上没有未熔化的唇缘。在完成焊接之后，可以使用任何常规的成形或任何成型工艺来形成片材（30,32）。

摘要： A method of butt welding a pair of sheets (30, 32) minimizing or eliminating edge preparation of filler metal. Sheet edges (34, 36) are abutted with a surface mismatch (48) so that a portion (88) of the edge of the mismatched sheet (32) is above the weld interface (58) and exposed to the high energy radiation welding beam (40). The sheets (30, 32) are inclined at an acute angle from the horizontal plane (54) and transverse to the welding direction so as to encourage the flow of molten metal from the mismatched sheet (32) into the weld interface (58) region. The sheets (30, 32) can also or alternatively be inclined so as to introduce an acute angle between the weld line (56) and the horizontal plane (54), sloping downward in the welding direction (104), to minimize weld defects. The completed weld (44) forms a sheet blank that can be formed or contoured.
