《电焊机基本标准》(报批定稿)中明确规定630安及以下的电弧焊机的额定焊接电流等级采用 R5优先数系,是一项十分重要的规定。国内外实践证明,凡能正确采用优先数系来确定主参数系列的产品,均能体现技术经济上的合理性,能够用较少的品种规格,充分满足使用的需要。现在我国电弧焊机额定焊接电流系列采用 R5优先数系,必将对电焊机品种的合理发展、主参数系列的统一、产品批量的扩大以及有利于配套、互换、维修等方面产生深远的影响。
The Basic Standard for Welding Machines (Draft Approval) clearly stipulates that the rated welding current level of 630A and below is based on the R5 priority number, and is a very important requirement. Practice at home and abroad has proved that anyone who can correctly use the first few series to determine the main parameters of the series of products, can reflect the technical and economic rationality, with less variety of specifications, fully meet the needs of use. Now our country arc welder rated welding current series using R5 priority number system, is bound to the reasonable development of the welder variety, the main parameters of the unity of the series, product batch expansion and is conducive to supporting, exchange, maintenance and other aspects have a profound impact .
