我厂过去对船上的生活室、工作室、冷藏库以及围板等均用泡沫聚苯乙烯板作绝热材料,施工麻烦且有毒性。后来,我们采用超细玻璃棉作绝缘材料,应用碰钉焊工艺施工,取得了较理想的效果。碰钉焊设备碰钉焊设备是由焊接电源、焊接控制箱、碰钉焊枪等组成,如图1、2所示。碰钉焊时,由于时间短促,碰钉尖端电流密度较大,故对焊机的功率要求大,最好在500A,空载电压在80～90V。在实际生产中,采用了AX5-500直流焊机。 In the past, our factory used foam polystyrene board as heat insulation material for the living room, studio, cold storehouse and wallboard of the ship, which was troublesome and toxic to the construction. Later, we use ultra-fine glass wool as the insulation material, applying the nail welding technology construction, and achieved satisfactory results. Bumper welding equipment Bumper welding equipment by the welding power supply, welding control box, stud welding torch, etc., as shown in Figure 1,2. Butt welding, due to short time, hit the nail tip current density, so the welding power requirements, preferably at 500A, no-load voltage at 80 ~ 90V. In actual production, the use of AX5-500 DC welding machine.
