Description

直流快频次脉冲焊机 技术领域

诸多在航空航天和相关行业里我们日常要焊的材料,诸如:CMSX-10,In738,713,625,C263,PK33,MAR-M 247,René 80,René 142和钛合金等,可以在没有氩气室和氩气拖罩的情况下完成焊接。同时能极大的减小开裂和变形。
申请内容
本申请所要解决的技术问题总的来说是提供一种直流快频次脉冲焊机。本申请能够轻易产生细小焊缝因而减少热量影响区,与传统焊接过程相同,高适应性,钛焊接无需氩气室,能采用传统焊接的标准配件,高机动性,能自动化在形状复杂的零件。
为解决上述问题,本申请所采取的技术方案是:
一种直流快频次脉冲焊机包括单元测试模块,采用EP244KE2芯 片;在单元测试模块中包括DPM模块,进行数据输出;编码器,实现焊接物料参数变为数字参数;在单元测试模块输出端连接有程序锁;

直流快频次脉冲焊机由超快速电源控制电弧特性,可以由程序控制,以尽量减少热影响区和电弧的宽度创建精确的电磁场。这些系统提供了更高的焊接质量和远远超越逆变的控制技术,以实现更深的熔深和更窄的焊缝。焊机产生的柔和的电弧,使焊接更少的依赖散热器,同时变形也保持在最低限度。
本申请增强了电弧力度或者在低电流输入的情况下,也可以有足够的穿透力。可以改进那些对热量输入非常敏感的关键焊接,同时仍然达到完全熔透。此外,当在进行填丝焊的时候,在最终的显微结构上,也可以发现由于熔池的减小而产生的显著优势。这些卓越的特性,本申请在焊接单晶和定向晶产品时特别有优势。
本申请设计合理、成本低廉、结实耐用、安全可靠、操作简单、省时省力、节约资金、结构紧凑且使用方便。
