Weld line is the key part of ERW steel pipe because the impact toughness of its raw material is multiple times higher than that of seamless steel pipes. The impact energy of weld line can reach 60% of the raw material by controlling impurity content in raw material, the height and direction of the burr, mold border shape, welding leg, welding speed, heating power and frequency, welding extrusion capacity, the depth and temperature of intermediate frequency, as well as air-cooled length. Seamlessness can be realized if further optimization methods are adopted.

由于ERW钢管母材的冲击韧性数倍于无缝钢管，焊缝处的冲击韧性是ERW钢管的关键，通过控制原材料杂质含量、纵剪毛刺高度与方向、成型边部形态、焊角、焊接速度、加热功率与频率、焊接挤压量、中频退伙温度与深度、空冷段长度等工艺参数保证了焊缝的冲击功达到母材的60%以上，如进一步优化，可实现焊缝冲击功接近母材，从而实现性能无缝化。
