浅谈PE管焊接的质量问题-焊机的加热时间

发布者:admin 时间:2019-01-10 15:26:00

  在实际的施工过程中发现即使按照PE管金福彩票焊接机厂家规定的时间进行加热并考虑了温度补偿,但为什么还是会出现焊接质量问题(过焊或熔合情况不好)?

PE管

  这是因为有时在低温、大风环境下,PE管金福彩票焊机的设计考虑了气温因素会实现自动补偿;但是如果施工人员忽略了空气快速流动会在焊接过程中从焊接部位带走大量的热能,那么很可能会因加热时间偏短而发热量不够导致熔合不好;有时在晴朗、炎热环境下,除了环境温度很高之外,由于现场条件有限,在太阳光下曝晒过的管材管件温度远高于环境气温(有时会达到60 度以上),如果此时仍按厂家设定的加热时间进行焊接,很可能会出现过焊现象。
