摘要
针对广泛应用于工程船舶分段的中厚板I型坡口不清根焊接,易出现气孔、未焊透、夹渣等缺陷的现状,分别进行了8mm、10mm、12mm板厚不同切割方式、不同间隙拼板Ⅰ型坡口试验,探究了切割方式、装配间隙、焊接方法对焊接缺陷的影响,并分析了缺陷产生的原因。
The welding defects of pore, incompletely filled groove, slag inclusion and so on are easily to occur in the I-groove of medium plate when its weld root hasn＇t been cleaned. The 1-groove tests are carried out with different cutting ways, jointed boards of different clearance and different thickness boards. The influence of cutting way, assembling clearance and welding way to welding defect is studied, and the cause of welding defect is analyzed.
