点焊工艺目前已广泛地应用于航空工业。点焊质量的无损检测是推广点焊工艺的关键一环,引起了有关人员的极大重视。六九年我厂与六二五所协作研究成功点焊超声波自动检测方法。这种方法不仅能及时地发现焊点内的裂纹、飞溅、缩孔等缺陷,而且还能可靠地检测出焊点内的危险缺陷——脱点,又能粗略地估算焊点熔化核心的大小。同时能做到边点焊、 Spot welding technology has been widely used in the aviation industry. Spot welding quality nondestructive testing is to promote the key part of the spot welding process, causing great concern to the staff. Sixty-nine I plant and six two five research collaboration spot welding ultrasonic automatic detection method. This method can not only find the cracks in the solder joints in time, defects such as splash, shrinkage, but also reliably detect the solder joints within the dangerous defects - off point, but also a rough estimate of the size of the weld melting core . At the same time can do edge welding,
