焊接

  • 拼板的对接焊缝是否全焊透,正面焊完后,反面是否用砂轮片打出坡口后再焊接保证根部焊透(根据WPS)。

  • 型钢与底板组装等需要间断焊的位置,焊前用抛光轮是否打磨、去除锈蚀杂物。间断焊点焊是否划线,必须严格按照划线进行焊接,点焊时点在每段焊缝中间以确保在焊接过程中完全融化。

  • 钢板拼接,采用自动焊,焊缝的余高是否控制在要求高度的范围内

  • 钢板拼接、角焊缝,焊接前是否将焊缝两侧25mm的油污和锈蚀清理干净,且打磨至金属光泽。焊前准备是否按照车间陈列的样板。不锈钢与碳钢焊接,碳钢的焊接区域是否打磨至金属光泽。

  • 焊接前是否有对设备进行检查;焊枪,焊机及气瓶的检查,清洁度检查及计量标签

  • 焊接参数和焊材的选用等是否按照WPS的要求;焊机性能是否完好?线缆接头有无断裂?气体流量是否按照WPS的要求?

  • 吊耳、支撑臂等重要部位的焊接检验。<br>尤其注意焊缝焊接摆动幅度

  • 法兰焊接必须采用分段焊,所有的法兰下料时是否放余量,焊接后是否进行整形。

  • 焊接高度是否满足图纸要求(根据通用焊接技术要求)。<br>

  • 目视可见的焊接缺陷,如未融合、焊接裂缝、咬边、焊瘤、气孔等是否100%全部返工;<br>

  • 焊接中所用的焊丝盘上是否用记号笔写上仓库的材料追踪号。焊丝盘是否有保护
