当前位置:焊补不锈钢铸件缺陷的效果
[来源:www.hslcasting.com.cn] [作者:精密铸造] [日期:18-06-05]
HB-J3型精密补焊机在研发成功之前,在精密铸造行业里对于高碳材质产品的焊补还没有很好的解决办法,多数产品在铸造出来后发现有气孔沙眼裂纹等缺陷后选择了报废回炉,这样势必增加了企业的生产成本和二次回炉对环境的破坏,而HB-J3型精密补焊机的研制成功和高碳焊丝的开发生产,对于大多数精密铸造公司在焊补高碳材质产品来讲终于有了降低解决办法了。 HB - J3 precision before repair welding machine research and development success, in the precision casting industry for high carbon material product welding repair is not a good solution, most of the products, after arrival in casting out after the stomatal crack defects such as trachoma chose scrap recycled, this will increase the enterprise's production costs and secondary and recycled to the destruction of the environment, and the successful development of HB - J3 fill precision welding machine and the development and production of high carbon wire, for the majority of precision casting in weld high carbon material products of the company, finally had the lower solution. 一、 设备性能及工作特点介绍 A, equipment performance and working characteristics is introduced 设备型号:HB-J3型精密补焊机设备性能参数: Equipment models: fill HB - J3 precision welding equipment performance parameters: 型号 HB-J3型 Type of HB - J3 使用电源:单相220V±20% -50HZ To use power: single-phase 220 v + 20%, 50 hz 功率消耗: 10-1200W Power consumption: 10-1200 - w 瞬时最大输出功率 :大于40KW The instantaneous maximum output power: more than 40 kw 弧焊输出 :功能1-功能4可切换模式 Functions of arc welding output: 1-4 can switch mode 输出电流 :输出脉冲电流1-99可调 Output current, output pulse current adjustable 1-99 输出时间 :输出脉冲时间1-99可调 The output time: adjustable output pulse time 1-99 电阻焊输出 :单点和连续(焊丝0.3-1.2mm可调) Resistance welding output: single point and continuous adjustable (0.3 1.2 mm wire) 氩气延时时间: 9S Argon gas delay time: 9 s 焊丝规格范围 :0.2mm-2.0mm Scope: wire specification 0.2 mm to 2.0 mm 堆高焊厚度 :任意 Stacking welding thickness: arbitrary 冷却方式 :空冷 Cooling: air cooling 主机体积 长415mm×宽200mm×高225mm Host long size 415 mm * 415 mm * 225 mm wide 重量 :13Kg 13 kg weight: 工作特点:采用微电脑芯片控制输出电流和时间,使得脉冲电流〔199〕幻和电压(199)可任意调节。 单次熔焊可以在几十毫秒〔1秒=1000毫秒)内完成焊丝与工件的熔接;相对氩弧焊(大千几秒)来说其 传导到工件的热量相当少,所以就基体本身而言,发热量较少,焊点以外基体区域升温小,对基体不会产生退火、淬火效应;又由千每个焊接脉冲产生的熔池小千2饥饥3,所以焊接接头焊接应力也较小;虽然一个焊点需要很多单个熔池产生,但焊点的应力方向分散,工件受到的集中应力也较小,因此补焊后工件变形小,且不容易引起焊接裂纹。釆用氩气保护光焊丝焊接,避免了焊接夹渣等问题的产生。 Work features: adopts microcomputer chip control, output current and time makes the pulse electric current (1-99) phantom and voltage (1-99) can be adjusted. A single welding can in a few milliseconds (1 second = 1000 milliseconds) to finish the welding wire and workpiece; Relative argon arc welding (seconds) intended for the heat conduction to the workpiece is less, so in terms of substrate itself, calorific value is less, solder, outside matrix to matrix does not produce annealing, quenching effect; And pulse generated by thousands of each welding molten pool small thousand 2 hunger hunger 3, so the welding joint welding stress is smaller; Although a solder joints need many single molten pool, but solder joint stress direction dispersion, concentrated stress of workpiece was also smaller, so after repair welding deformation is small, and it is not easy to cause weld cracks. To adopt argon protection of bare wire welding, to avoid the welding slag, etc.
