4) hydrogen induced crack 氢致裂纹 1. This paper deals with the initiation and propagation of hydrogen induced crack while 10CrNi3MoV steel of 590 MPa grade was welded by MIG welding using WM960 S wire and Ar+20%CO 2 mixed gas without preheating. 研究了气体保护焊 (WM96 0 -S焊丝和Ar...
Residual stresses due to cooling and locally hardened areas in the heat-affected zone can lead to hydrogen-induced cold cracking. The absorption of hydrogen by moist welding electrodes, however, is considered a resolved issue, as manufacturers employ specific drying procedures and provide guidelines ...
Susceptibility to hydrogen-induced cracking (HIC) was evaluated in steel welds for quenched and tempered armouring steel of 4.5 mm thickness. The welds were produced using the shielded metal arc welding process with low heat support and AWS E11018M 2.4 mm consumable. The susceptibility to HIC ...
The effect of hydrogen content and welding conditions on the hydrogen induced cracking of the API X70 steel weld The self-restraint testing was used to investigate the influence of hydrogen content, preheating, and post-heating on the sensitivity of welding of API X70... A Talebi Hanzaei,SPH ...
1)hydrogen induced cracking氢致开裂 1.Thehydrogen induced cracking(HIC) of X70 pipeline steel was studied in H2SO4 solutions with different concentrations by means of electrochemical charging.采用电化学充氢的方法研究了X70管线钢在不同浓度硫酸溶液中的氢致开裂(HIC)行为。
Presented here are the results from a series of experiments in which dissimilar metals welds were made using the gas tungsten arc welding process with pure argon or argon-6% hydrogen shielding gas. The objective was to determine if cracking near the fusion boundary of dissimilar metal welds could...
6) hydrogen cracking 氢致开裂 1. Because of the fast cooling of flowing medium,the hydrogen cracking occurs easily under in-service welding. 因此,在避免烧穿的前提下增大焊接线能量或减小管内介质的冷却能力,减少高硬度不平衡相的形成,可以降低HAZ氢致开裂敏感性。 2. In order to study the ...
Stress-oriented hydrogen-induced cracking (SOHIC). Sulfide stress cracking (SSC): Cracking in steels of high strength or high hardness. These four types of hydrogen damage are illustrated in Figure 1. For any of these to occur, there must be a corrosive environment and a material that is ...
Those represent hard and simultaneously more brittle areas which can be sensitive to hydrogen induced cracking. The bonding line can be also a potential position for hydrogen concentration. After welding and exposition in corrosion solution bubbled with sulphide hydrogen the titanium of commercial purity...
