随着轻纺工业的迅速发展,厚度为0.5mm以下的不锈钢超薄板结构的应用日趋增多。超薄板焊接较为理想的方法是微束等离子焊,我厂利用原有的TIG自动焊设备,通过适当的工艺措施,顺利地焊接了厚度为0.05～0.5mm不锈钢薄板,及2500孔/cm~2不锈钢丝网布等薄件结构。一、薄板焊接的主要问题 (一)TIG小电流的电弧稳定性在试验中发现,当电流小于7A左右,电弧就不稳定,不能用于焊接。这现
With the rapid development of the textile industry, the application of the stainless steel sheet structure with the thickness of 0.5 mm or less has been increasing. Ultra-thin plate welding is the ideal method of micro-beam plasma welding, I use the original plant TIG automatic welding equipment, through appropriate process measures, the smooth welding of stainless steel sheet thickness of 0.05 ~ 0.5mm, and 2500 holes / cm ~ 2 stainless steel mesh cloth thin structure. First, the main problems of sheet metal welding (A) TIG small current arc stability In the test found that when the current is less than about 7A, the arc is unstable and can not be used for welding. This is now
