【Summary Description】 What are the thermite welding materials respectively Thermite welding materials, respectively, flux, sand mold, crucible. ① If the wall thickness of the pipe is less than 3.0mm, the wire shall be connected by fixture or brazing; when the pipe is lined or the wall thickness of the pressure pipe is less than, the wire shall not be connected by thermite welding. ② After the surface of the pipe is cleaned, the thickness of the pipe wall shall be measured by ultrasonic method. If the pipe wall thickness is less than 90% of the nominal wall thickness or there are interlayers and pitting pits, no aluminothermic welding shall be performed. Try to weld on horizontal pipes. ③ If the cross-sectional area of the cable exceeds, the cable should be divided into several strands for separate welding, each conductor area does not exceed, to ensure that a welding dose does not exceed, in order to avoid the impact of welding heat on the pipe structure. ④ The distance between the welding position and the circumferential weld is greater than that of the longitudinal weld, so as to avoid welding at the tee or elbow. The spacing between the two welding spots should be greater. The same position can only be welded once. If the first welding fails, the Welding materials shall be cleaned up before the second welding or welding at another position. ⑤ During the implementation of thermite welding, the allowable pressure in the pipe shall be calculated according to the following formula. Pp = 2S(T-1.59) x. In the formula, Pp-allowable pressure in the pipe during welding, MPa. Minimum yield stress of S pipe material, MPa. D Nominal outer diameter of pipe, mm. What is the material of the welding of aluminum alloy? This is the basic formation of argon arc welding. It is a re-casting process. After the molten pool is formed in the parent body, the welding wire is added, so the main component should be the material composition of the welding wire, and there is a little parent body molten material.
