1·It is weld line.

它是焊接线。

2·Too high switch point: empty part, weld line, sink mark, and small.

转压点太高：产品充模不足，熔接痕，凹陷，尺寸偏小等。

3·Weld Area crack. A crack in or immediately adjacent to the weld line.

焊缝区裂纹。在焊缝线或紧靠焊缝线出现的裂纹。

4·In engineering, in order to make the weld line even and reliable, it is needed to cut the weld opening accurately.

工程上，为了使钢管相贯处焊缝均匀，焊接可靠，需要将钢管的焊口准确切割成型。

5·The trajectory planning of posture adjustment is presented for a weld mobile robot during auto-searching weld line.

主要研究移动焊接机器人在自寻迹过程中位姿调整的轨迹规划。

6·In the tracking trials of sidelong, reflex and curve weld line, the system can all meet the demand of the tracking precision.

在斜线、折线和曲线三种不同形状待焊焊缝的跟踪试验中，系统都能满足药芯焊丝水下自动焊接的要求。

7·But injection molding often results many product's problems such as short shots, overflow edges, warp, weld line, dimension error and so on.

但是，注塑成型常常出现各种质量问题，例如，短射、飞边、翘曲、熔接痕和尺寸误差等。

8·By comparing analysis results, the best moulding project is chosen filling effect being unifor with unobvious weld line and centralizing air traps.

通过比较分析结果，选择出填充效果均匀、熔接痕位不明显、气穴位置集中的较好成型方案。

9·Drop transfer in the process of MIG welding is very complicated and quality of weld line is easily impacted by welding parameters coupled with each other.

MIG焊过程熔滴过渡过程复杂，影响焊接质量的参数多，相互间耦合性强。

10·The peculiarity and error of CAE were analysed, and corresponding control measures for the weld line were proposed according to different affecting factors.

分析了熔接痕CAE的特点及误差，并针对不同影响因素，给出了相应控制对策。
