TIG welds novel nozzle with vortex impeller

The utility model relates to the field of welding technique, more specifically says and relates to a TIG welds novel nozzle with vortex impeller, and fixed scaffold weldment is on the inner wall of cylindrical nozzle main part, and little vortex impeller all sets up on the fixed bolster with big vortex impeller. This TIG welds novel nozzle with vortex impeller simple structure can adapt to multiple welding environment, can utilize the vortex impeller to produce rotatory air current, arcing central zone's negative pressure, and electric arc arc column along radial shrinkage improves the straight straightness of electric arc, increases the weld penetration, utilizes rotation air current butt weld molten bath to stir simultaneously to grain refinement improves welded joint's mechanical properties. 本实用新型涉及焊接技术领域，更具体地说涉及种具有扰流叶轮的TIG焊新型喷嘴，固定支架焊接在圆柱形喷嘴主体的内壁上，小扰流叶轮与大扰流叶轮均设置在固定支架上。该具有扰流叶轮的TIG焊新型喷嘴结构简单，可以适应多种焊接环境，能够利用扰流叶轮产生旋转气流，形成电弧中心区域的负压状态，电弧弧柱沿径向收缩，提高电弧的挺直度，增加焊缝熔深，同时利用旋转气流对焊接熔池进行搅拌，以细化晶粒，提高焊接接头的力学性能。
