Appendix Appendix Here are the causes and solutions for these three defects in 堀蘀II.Generation and prevention of general welding defects welding: To welders: I.Weld joint cracking Welders, Hi. J422 welding rods manufactured by our company Causes for cracking of the weld joint during welding are as have good welding process. In addition, its operation,mechanical below:stress, restraining force, rigidity, chemical composition, properties and chemical composition not only fully meet the reserved gap of the weld joint, current, weld bead and cleanliness requirements of national standard (GB/T5117-1995), but also of the base metal. All these factors may result in cracking of the obtain recognition of classification societies in eight countries, weld joint. Although causes are various, cracking of the weld joint including China (CCS), UK (LR), France (BV), the United States may be attributed to multiple factors in each occasion, or (ABS),Norway (DNV), Germany (GL), Japan (NK) and South attributed to two or three factors. However, regardless of how Korea (KR).Our company is the first in the industry passing the many factors, there must be one main factor. There are also cases ISO9000 international quality assurance system certification, and in which all conditions impose no influence and only one factor it guarantees that each batch of welding rods and each one it results in cracking of the weld joint. Therefore, when the weld joint manufactured are fully consistent with the quality standard. cracks, it is a must to correctly analyze the main and secondary J422 welding rods manufactured by our company have the factors resulting in cracking first and then take corresponding advantage of good crack resistance, that is, the weld joint measures to solve this problem based on the above analysis. generally does not have crack or split. The weld joint formed in the welding process refers to the weld Both crack and split refer to the cracking of the weld joint. In joint formed by the molten welding rod and base metal under high general, those that are hardly observed by naked eyes refer to temperature due to current. In this process, the welding rod and cracks;Those that can be easily seen are splits. the base metal turn into high-temperature liquid from solid, which Quality of the weld joint depends on four aspects: is accompanied by thermal expansion and then liquid turns into 1.Welding structure solid accompanied by cold contraction. Thermal expansion and 2.Welding specification cold extraction naturally makes the welding structure generate 3.Base metal stress. Some welding structures are inherently restrained and 4.Welding rod rigid. The above four aspects decide whether the quality of generated In the welding process, solid turns into liquid (so-called molten weld joints is good and satisfies quality requirements, or not. iron) and then liquid turns into solid, namely, weld joint is formed. Quality of the weld joint refers to: mechanical properties, Liquid turns into solid (that is, molten iron turns into grains). The chemical composition, crack or split, pores and undercut. In the process in which molten iron turns into grains is the crystallization welding process,crack or split, pores, undercut and other defects process. occasionally occur to the weld joint.

Appendix Appendix middle position, and finally occurs in the middle of the weld joint. and welding rods of large specifications being applied to the first Due to the effect of thermal expansion and cold contraction, the weld bead. For a whole large structure, the dispersed welding welding structure is a昀昀ected by stress or restraining force or shall be applied to all the weld joints. Otherwise, although there is rigidity, so that grains of the base metal cannot connect together. no cracking weld joint, there is excessive residual stress. What to do when the reserved gap of the weld joint is too In less severe cases, small crack may appear in the middle of the weld joint, while in severe cases, obvious split may appear. Even large? Adopt welding rods of small specifications and small current and then perform welding along one side of the weld joint if the chemical composition of the base metal and the welding rod good, crack or split may occur due to the restraining force and (one-sided su爀昀acing), or perform welding simultaneously on both is rigidity of the welded structure, as well as the stress generated in sides (two-sided surfacing),which depends on the reserved gap of the welding process. If the chemical composition of the base the weld joint, thickness of the base metal and depth of the weld metal and the welding rod is poor (high carbon, sulfur and joint. phosphorus content); or reserved gap of the weld joint is too large, For the welding structure whose chemical composition of the too many impurities exist at the edge of the weld joint, the current base metal is poor, in addition to several factors above, it is also necessary to select low-hydrogen welding rods, such as J426, is too large, the welding speed is too fast or too low, the weld bead J427, J506 and J507, because these welding rods have excellent is too wide, etc., cracking of the weld joint will be worse. Cracking crack resistance. However, the above method to prevent cracking of the weld joint occurred on the welding engineering site is mostly attributed to stress, restraining force and rigidity. It can be said that of the weld joint is also required. When the base metal or thick stress, restraining force and rigidity are the main factors for plate is made of medium carbon steel and other alloy steels, low cracking of the weld joint. hydrogen welding rods must be used. The effective way to solve cracking of the weld joint attributed II.Pore stress, restraining force and rigidity is to: Adopt fixed welding or The general cause for pores of the welding joint is dirty welded to dispersed welding. The so-called fixed welding is: First of all, position, in which, there is rust, oil stain or welding slag. Therefore, adopt small current, string bead, short-distance welding to fix all besides removing impurities observed on the surface, it is also weld joints of the weldment or the weld joint at important position. required to dry internal moisture through gas welding at the edge This makes it difficult for the weldment to generate large stress. of the weld joint of base metal before welding for the weld joint Even if the weldment is fixed everywhere, it is not allowed to weld subject to X-ray detection. The common cause for pores of the forward from the same position, let alone adopting large current welding joint is too large current. Shapes of weld joints are diverse: Such as downward welding, vertical welding, horizontal and welding rods of large specifications. Welding shall be performed at different locations so as to avoid too much heat in welding, overhead welding, flat fillet welding, ve爀琀ical fillet welding, local position. For rigid structures with restraining force, the same thickness of the base metal, groove shape, multilayer welding and method can be adopted as a solution. cosmetic welding. In order to avoid generation of pores in weld The so-called dispersed welding means performing welding at joints of any types, in addition to cleaning the weld groove, the different locations, absolutely forbidding sequential welding of current must be adjusted appropriately in the welding process. large structure from the same position. How to determine the standard of appropriate current? Please For large structures, in addition to fixed welding first followed note that, the coverage volume of the molten slag is better to be half of the volume of the molten bath, absolutely for bidding less by dispersed welding, it is also required to prevent large current Tianjin Golden Bridge Welding Materials Group Co.,Ltd - - - - - - - - - - - 7 - Tianjin Golden Bridge Welding Materials Group Co.,Ltd 52 - - - - - - - 52 - - - 6
