1. It analyzes 9 common defects causes and its prevent methods such as slag, pre-weld, uncompleted weld, forged weld, gas pocket and skip weld in the high frequency welded pipe production. 分析了高频焊管生产中夹杂物、预弧、熔合不足、边部熔合不足、中部熔合不足、粘焊、铸焊、气孔、跳焊等9种常见焊接缺陷产生的原因及其防止措施。
2. Because of stable weld, laser weld suits three dimensional weld such as weld of the smaller diameter steel pipe and copper chip, and high speed for accurate instruments. 激光焊接，焊接形态稳定，比较适合于较细钢管、钢片等薄板的立体焊接，也适合于精密仪器的高速焊接。
3. Regarding to submerged arc weld multi-pass weld track and height of weld gun, two-dimension track system is designed. 针对埋弧焊多道焊的焊缝跟踪以及焊枪高度跟踪问题，设计了一种二维跟踪系统。
4. D , do not weld fully do not weld fully to denote weld superficially continuous or intermittent groove. 未焊满未焊满是指焊缝表面上连续的或断续的沟槽。
5. WELD TENSILE TEST shall be carried out after the height of the flash or weld bead (weld reinforcement)of specimen has been removed. 焊管张力测试需在一定高度下进行一瞬间运动或将焊管样的本焊缝补强处的焊珠去除。
