随着科学技术的不断发展,人们对焊接自动化程度的要求越来越高。自动焊管机已在碳钢和不锈钢等材料上获得了成功的应用,但在铝和铝合金上应用一直是个难题。其主要原因是接头中的气孔率太高,不能满足焊接质量要求。 With the continuous development of science and technology, people are increasingly demanding on the degree of automation of welding. Automatic pipe welding machines have been successfully applied to materials such as carbon steel and stainless steel, but the use of aluminum and aluminum alloys has been a challenge. The main reason is the porosity of the joint is too high, can not meet the welding quality requirements.
