    • PROBLEM TO BE SOLVED: To provide a laser joining material free of thermal strain when iron-based metallic plates are continuously welded to each other, wherein each plate has a length of ≥1 m along the welding direction, a width of 30-500 mm, and a thickness of 0.8-3 mm. SOLUTION: When iron-based metallic plates are superimposed on each other, with the fillet continuously welded by laser; in a cross section vertical to the welding direction, fused end points A, B and deepest penetration point O in the thickness direction are connected to form and define a triangle AOB. Where x is the length of the side AB equivalent to a laser incident port, y, z are the length of other sides AO, BO respectively, and h is the length of a perpendicular from the point O to the side AB, laser joining is performed under the conditions; (x+y+z)/x multiplied by h/x, namely, the value of h(x+y+z)/x 2 ≥2.

    • 要解决的问题:为了提供一种当铁基金属板彼此连续焊接时没有热应变的激光接合材料,其中每个板沿着焊接方向具有≥1m的长度,宽度为30 -500mm,厚度为0.8-3mm。

      解决方案:当铁基金属板彼此重叠时,通过激光连续焊接圆角; 在垂直于焊接方向的横截面中,连接熔融端点A,B和厚度方向上的最深穿透点O,以形成并限定三角形AOB。 其中x是与激光入射口相当的边AB的长度,y,z分别是另一侧AO,BO的长度,h是从点O到AB的垂直的长度,激光接合是 在条件下进行; (x + y + z)/ x乘以h / x,即h(x + y + z)/ x 2 ≥2的值。 版权所有(C)2009,JPO&INPIT
