| 3. | A cavity is made on both sides of weld bead 在焊道表面两侧作一空腔。 |
| 4. | So the shape and the penetration of welding bead will change , result in the lack of the penetration 因此焊缝熔深也发生变动,容易产生熔深不足等缺陷。 |
| 5. | Using the heat of welding to vapour water , cooling rates are lowered on the weld bead and heat - affected zone 利用焊接时的加热使水汽化,不仅使焊道而且使热影响区的冷却速度减慢。 |
| 6. | As is known to all , the protecting effect of tig welding is fine . the metal in welding bead is pure 众所周知, tig焊焊缝保护效果好,焊缝金属纯净,特别适用于焊接易氧化的有色金属及其合金。 |
| 7. | The lack of the penetration of welding bead is a typical defect . it will do great harm to the quality and safety of the welding structure 焊缝熔深不足是焊缝及焊接接头内部的一个典型缺陷,会给焊接结构的质量及使用安全带来危害及影响。 |
| 8. | The effect of the changes of the wire extension on the penetration of welding bead is analyzed and a project of the controlling to the penetration of welding bead is established in this paper 本文分析了焊接过程中由于干伸长的变化对焊缝熔深的影响,确定了熔深控制方案。 |
| 9. | The penetration of welding bead is hard to be checked directly in practice , so the control on the penetration of welding bead is mainly realized by adjusting the related factors 由于焊缝熔深在实时状态下难以直接检测,因此,对焊缝熔深的控制主要是通过调节与其相关量来实现的。 |
| 10. | Using 304l wire as the cladding material , the experimental results proved that the relationship among welding bead width , welding current and speed could be expressed with a plane in an x - y - z coordinate 对采用304l不锈钢作为单一熔覆材料的成形试验研究表明:电流、成形速度与成形轨迹宽度的关系可以采用平面几何关系表示。 |
