雷达产品的生产中,遇有大量的厚度在0.5～2毫米的LF_(21)、LF_2等防锈铝合金的焊接。除尽量把焊缝设置成变形小而易修锉的角焊缝结构外,仍不可避免在各结构上出现平对接的焊缝。雷达产品的零件,如锥形天线、大型抛物面天线、反射体、辐射体、骨架、框架、机壳等,它们的精度要求很高——焊疤经修锉后和母材一样平整;变形小;便于修形达到设计要求。为此对焊接工序提出了较高的 Radar production, the case of a large number of thickness of 0.5 ~ 2 mm LF_ (21), LF_2 and other rust-proof aluminum welding. In addition to try to set the weld to a small deformation and easy filing fillet weld structure, still inevitable in the structure of the flat butt weld. Radar products, such as conical antennas, large parabolic antennas, reflectors, radiators, skeletons, frames, enclosures, etc., require high precision. Welds are as flat as the base metal after filing; ; Easy to repair to meet the design requirements. To this end the welding process put forward higher
