我厂生产的某产品,在冷挤压钢管上需装上两条环状铜带,大带宽16毫米、厚3.5毫米;小带宽8.5毫米、厚2.2毫米。钢管材料为D60钢,管子外径85毫米。铜带的作用是密闭高压气体,在使用中承受复杂应力。长期以来,在生产上采用的是嵌压工艺,这种方法生产率低,耗铜量大、生产费用高,而且在使用中易发生脱带现象。用等离子堆焊铜带代替嵌压铜带,获得了满意的结果。堆焊设备等离子弧堆焊设备由焊接电源、控制系
I plant a product, in the cold extrusion of steel pipe to be fitted with two annular copper, a large bandwidth 16 mm, thickness 3.5 mm; a small bandwidth of 8.5 mm, 2.2 mm thick. Steel material is D60 steel, pipe diameter 85 mm. The role of copper is sealed high-pressure gas, in use to withstand complex stresses. For a long time, the use of embedded pressure in the production process, this method of low productivity, high consumption of copper, high production costs, and easy to occur in the use of off-band phenomenon. With plasma surfacing copper tape instead of embedded copper, obtained satisfactory results. Surfacing equipment Plasma arc welding equipment by the welding power supply, control system
