摘要
通过积极布局智能制造,引进MICROBO便携式全位置智能焊接机器人用于船坞搭载阶段合龙焊缝的焊接。MICROBO能够自动计算每条焊道使用的焊接参数,默认使用实芯焊丝,为提高效率,换用药芯焊丝。给出手动调整焊接参数的建议,包括将每条焊道的电流调大20~30A,电压调大3~5V,焊接速度降低40~60mm/min。提出平对接、立对接、斜45°对接等3个不同焊接位置的焊接工艺。在外场施工时应注意避免风对焊接质量的影响,专门制作的一体式挡风装置可以有效减少气孔缺陷。机器人对坡口的适应性不强,使用中应注意控制坡口的切割质量和装配精度。
Through the active layout of intelligent manufacturing,the portable allposition intelligent welding robot MICROBO is introduced for the welding of closure weld at the dock loading stage.MICROBO can automatically calculate the welding parameters used for each welding bead.By default,it uses the solid cored wire,but in order to improve the efficiency,it switches to using the flux-cored wire.The suggestions for manual adjustment of welding parameters are given,including increasing the current by 20〜30 A,increasing the voltage by 3〜5 V,and reducing the welding speed by 40〜60 mm/min for each welding bead.The welding technologies in three different welding positions of flat butt welding,vertical butt welding,and oblique 45°butt welding are proposed.Attention should be paid to avoid the influence of wind on the welding quality in the external field construction,and the specially-made integrated wind shield can effectively reduce the porosity defects.The robot,s adaptability to the groove is not strong,so the cutting quality and assembly precision of groove should be controlled in use.
