氩弧焊接是使用钨电极,以惰性气体——氩气隔离电弧周围的空气,防止金属的氧化与烧损。这种焊接方法的特点是: 1.合金元素的烧损少,保证焊接后材料的理化性能; 2.焊缝中的氧化夹渣少,焊缝金属的组织致密,热影响区小,焊接变形小; 3.不用熔剂,焊后无需清理; 4.焊接铝和铝合金时,有阴极破碎作用,对熔池有净化作用,焊时可见性好; 5.焊缝成形好,整齐、光亮、洁净。因此,氩弧焊用于焊接耐热钢、不锈钢、铜和铜合金、铝和铝合金等,有良好的焊接质量。我厂设计制造的交、直流两用钨
TIG welding is the use of tungsten electrodes, an inert gas - argon to isolate the air around the arc, to prevent oxidation and burning of metals. The welding method is characterized by: 1. Alloying elements less burning, to ensure that the physical and chemical properties of the welding material; 2. Weld in the oxidation of slag less metal microstructure of the weld dense, small heat-affected zone, welding deformation Small; 3. No flux, no need to clean after welding; 4. When welding aluminum and aluminum alloy, there is a cathode crushing effect, purifying the weld pool, welding visibility; 5. Weld forming a good, neat, bright, Clean. Therefore, argon arc welding for welding heat-resistant steel, stainless steel, copper and copper alloys, aluminum and aluminum alloys, have a good welding quality.
