一、前言铝焊管是一种较新的管材生产方法.由于高频焊接方法的发明,铝焊管生产发展很快.特别是六十年代以来,在国外工业发达的国家中,铝焊管生产发展更迅速.以美国为例,1960到1965年间铝焊管的生产量增加了2.6倍,占铝管材总产量的30%,而进入八十年代提高到50%.苏联、日本、西德等国,铝焊管的产量约占铝材总产量的1~3%.随着工业的发展,焊管技术的进步,今后将有进一步增长的趋势.
I. INTRODUCTION Aluminum welded pipe is a relatively new method of pipe production. Due to the invention of high-frequency welding method, the production of welded aluminum pipe has developed rapidly. Especially since the 1960s, in the developed countries in foreign countries, In the United States, for example, the production of welded aluminum tubes increased 2.6-fold from 1960 to 1965, accounting for 30% of the total output of aluminum tubes, but increased to 50% in the 1980s. The countries such as the Soviet Union, Japan, West Germany, Pipe production accounts for about 1 ~ 3% of the total output of aluminum.With the development of industry, the progress of pipe technology, the future will have further growth trend.
