一般CO_2焊的飞溅损失均在4～6％左右,极易堵塞喷咀孔。为了减少飞溅堵塞喷咀,延长喷咀使用时间,本文着重于喷咀结构的改进。选用两种环型窄孔的新型喷咀、(图1中A和B型),以保证在较长焊缝上不堵塞喷咀。一、新旧喷咀在常温下的
General CO_2 welding splash loss are about 4 ~ 6%, easily blocked nozzle hole. In order to reduce the nozzle clogging spatter to extend nozzle life, this article focuses on the nozzle structure improvements. The choice of two new nozzles with narrow ring holes (type A and B in Figure 1) ensures that the nozzle will not clog on longer welds. First, the new nozzle at room temperature
