电阻焊接.电阻焊设备.机械和电要求

[中文适用范围]： 本国际标准定义并规定了用于以下设备的某些已确定的电气和机械特性： ——电阻点焊、 — 凸焊、 — 电阻缝焊、 — 顶焊 1) 和 — 闪光焊 2)。 本国际标准规定了设备规格中给出的信息以及用于测量这些特性的测试方法。 并非所有要求都适用于所有类型的设备。 包括以下类型的电源： ——单相交流焊接电流； ——通过焊接变压器的输出进行整流的单相焊接电流； ——单相逆变焊接变压器； ——通过对焊接变压器的输出进行整流而得到的三相焊接电流； ——焊接变压器（有时称为变频器）输入端具有电流整流功能的三相； ——三相逆变焊接变压器。 本国际标准不适用于与设备分离的焊接变压器。 注：IEC 62135–1 涵盖了电阻焊设备的安全要求。 [外文原描述]： ISO 669:2016 defines and specifies certain identified electrical and mechanical characteristics of equipment used for - resistance spot welding, - projection welding, - resistance seam welding, - upset welding[1], and ? flash welding[2]. ISO 669:2016 specifies the information to be given in equipment specifications and the test methods to be used for measuring those characteristics. Not all requirements apply to all types of equipment. The following types of power sources are included: - single phase with alternating welding current; - single phase with rectified welding current by rectification of the output of the welding transformer; - single phase with inverter welding transformer; - three phase with rectified welding current by rectification of the output of the welding transformer; - three phase with a current rectification in the input of the welding transformer (sometimes called frequency convertor); - three phase with inverter welding transformers. ISO 669:2016 Standard does not apply to welding transformers that are separate from the equipment. NOTE Safety requirements for resistance welding equipment are covered by IEC 62135?1. [1] Often referred to by the non-preferred term, butt welding. [2] Often referred to by the non-preferred term, flash butt welding.
