高頻電阻焊鋼管的生產特點

日期:2020-03-01

高頻電阻焊鋼管(erw鋼管)具有以下特點:

高頻電阻焊鋼管的生產特點

(1) 高頻電阻焊填充金屬是一種無壓焊。

(2) 高頻電阻焊焊接速度快,生產效率高。由于目前焊接區能量集中度高,加熱快,因而焊接速度快。如我國引進426臺機組,最大焊接速度45m/min,最小焊接速度15m/min。

(3) 焊縫熱影響區。由于焊接能量高度集中,加熱速度快,焊接速度快,工件自冷效果強,所以熱影響區大。

(4) 對焊接生產工藝和管理水平要求高。高頻焊接是電阻焊在連續生產線上的一種,其焊接速度快,生產效率高,影響焊接工藝的因素多,必須有較高的技術水平和管理水平,才能使整個生產線的焊接元件更加協調一致,達到穩定的焊接質量鋼管。
