Embodiment Construction
[0029] A specific embodiment of the present invention is: the size specification of the titanium-steel clad plate used is 3mm+3mm, which is obtained by rolling.
[0030] The method for full penetration welding of the titanium-steel clad plate includes the following steps:
[0031] 1) Processing welding groove: At the composite transition line of the welding section of the titanium steel clad plate to be welded, process a semi-elliptical groove along the length direction of the composite transition line, and the depth of the groove is a semi-elliptical short 1 / 2 of the axis a, the major axis b of the semi-ellipse is perpendicular to the bonding surface between the titanium coating of the titanium-steel composite plate to be welded and the steel base, the minor axis a of the semi-ellipse is 1-1.6mm, and the major axis b=1-2mm; the titanium-steel composite plate to be welded after processing the groove is as figure 1 shown.
[0032] 2) Clean up the welding area: clean the groov...
