In order to prevent welding due to the smaller gap bending, may be appropriate to take steps to set the gap with 2.4 Welding surface inspection, if any cracks and other defects must be immediately clear, nylon grinding wheel with a thin glial cleaned before they are allowed under a seam welding. electrode DC arc welding power reverse, welding material as HK-40 required to avoid overheating, therefore, to ensure penetration in the case of a small selection of the best specifications, such as the use of a smaller welding current, welding electrode is best not to swing, with a narrow bead, fast speed and short-arc welding (arc 25inn less) soldering addition, the HK-40 steel pipe welding prone to crater cracks, crater crater should try to fill every one should carefully check the finished weld, layer by layer, if any conditions should be checked to confirm no deficiencies can continue under a welding capping Road can be a little swing, the appearance of the surface after welding inspection and color check, requiring the surface forming a good weld reinforcement is less than equal to 2mm, weld and base metal should be smooth transition network , the table and not a slag, porosity, cracks welding parameters I Art Table 4 Table 4 welding parameters 2.5 l00% post-weld inspection at the premise of color qualified for testing 100% X-ray detection, according to GB3323-87 standard, Ⅱ grade pass in order to guarantee the quality of testing, the best single-wall method. 2.6 weld repair local repair failed weld machine grinding wheel can be used to remove defects in good condition after the repair welding; the entire weld rework, to use plasma arc cutting out and re-processing groove, with the plasma arc and grinders with the bevel grind, then the required tack welding 3 Conclusions based on the actual welding and experimental results show that carbon 25 -2O good centrifugal cast pipe welding, the use of appropriate welding] Arts parameters and welding sequence, you can get to meet the requirements of the mechanical properties of welded joints; using TIG + AW combination welding tube welding, the high productivity, weld quality. and stable, particularly in the use of TIG welding backing, current stability, the heat and the heat input is less concentrated, easy to overheat and porosity, weld stress evenly and prevent cracks, but also to ensure good penetration, forming a smooth back the United States; HK -40 centrifugal cast pipe welding selection of domestic R-N and SK high temperature nickel-based heat-resistant steel wire rod, the test evaluation is feasible.
