Fish scale welding VS chicken excrement welding, the perfect embodiment of welding technology

【Summary Description】 What is the highest level of welding technology? Is the beauty, is the parts sexy beauty, beauty a mess! TIG Welding is a kind of welding method. Pipe to pipe is directly welded, and its welding into fish scale shape is also referred to as fish scale welding. The welding method is mainly to select the welding point, energize it, knock out the arc with the welding rod head to melt the flux in the welding rod, and then swing the welding tongs left and right to make the welding core melt evenly at the welding position. It should be called fish scale welding because the welding effect is good. Welding skills 1.TIG welding itself belongs to open arc operation, which can well observe the shape and flow of molten pool, which is much superior to electrode arc welding. Welding skills 2. Controlling the stability of the hand during welding is the biggest key to avoid shaking and burning the dock pole to cause the molten pool to clamp tungsten. The control method can only be supported on the welded pipe or plate by the index finger holding the welding gun. Tungsten pole extension length can be selected according to the depth of the break, generally 3-5mm. The wire feeding method can be selected according to the size of the break. When the break angle is small, the welding wire can be placed in the middle of the molten pool and fed continuously. When the break is large, the wire can be fed at both sides (to be quite skilled and avoid touching the dock pole), and the welding torch can be moved left and right to make the edge fuse well. Regarding the full fish scale pattern on the surface, according to the scoring standard of the examination competition, the TIG weld surplus height is generally 0~2MM, and the surface is smooth and free of undercut. A blowhole. A crack. Not fusion can be. If beauty is not good enough, then there is another extreme, that is, chicken excrement welding that people can't stop.
