使用现代化点焊与缝焊装置时,焊缝的成形过程可以自动化,无需操作人员参与。因此焊接质量和可靠性在相当程度上由焊接规范主要参数的稳定性来决定。焊接电流的持续时间和强度是以高精度予以保证的,并且是决定焊接规范时不难给出的两项参数。焊接电流不可能根据焊机的调节直接确定,而通常是事先大致确定,然后逐渐校正,直至取得所需尺寸的焊缝熔铸区为止。因此,为了正确确定焊接规范和保证
With modern spot welding and seam welding, the forming of the weld seam can be automated without the need for operator intervention. Therefore, the quality and reliability of the weld is largely determined by the stability of the main parameters of the welding specification. The duration and intensity of the welding current are guaranteed with high accuracy and are two parameters that are not difficult to determine when determining the welding specifications. Welding current can not be directly adjusted according to the welding machine, but it is generally determined in advance, and then gradually corrected until the desired size of the weld zone is obtained. Therefore, in order to correctly determine the welding specifications and guarantees
