This book was released on 1987 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weld cracking tendancies of two newly developed controlled rolled and accelerated cooled high strength low alloy (HSLA) steels are compared with a standard normalized steel of approximately the same ultimate tensile strength (50 kg/mm2). All steels were welded with the shielded metal arc welding process at 0, 100, and 200 psig. Welding was conducted in a hyperbaric chamber under conditions of 100% humidity, using the Lehigh self restraint weld cracking test. A literature and mail survey was conducted on current U.S. practices in underwater welding using the shielded metal arc process. Test plates were subjected to macrascopic examinations to determine the extent of any existent cracking. it was found that the low carbon equivalent HSLA steels exhibited an excellent resistance to cracking, even when welded without the use of preheat. The general tendency for cracking susceptibility to lower as the cracking susceptibility factor (Pw) lowers was validated, even under hyperbaric conditions. However, it was substantiated that the current theories used to determine cracking susceptibility may be too conservative in predicting cracking susceptibility for HSLA steels.

Book excerpt: Weldment cracking is a broad complex field. Even if one considers only cracking of steel weldments, the problems range from cracking at temperatures near the solidus during welding to cracking at room temperature days, weeks, or months after welding is completed. Numerous reports of investigations in this field are contained in the published and unpublished literature. However, most of these reports cover only a particular problem in a specific area of the broad field of weldment cracking. This review attempts to cover the major aspects of the entire field of weldment cracking. Necessarily, the review is for the most part general, only being specific in a few instances to illustrate a point. (Author).

This book was released on 1984 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current American practices are surveyed to determine which weld cracking tests are used, and what methods are used to prevent and control weld cracking. The cracking resistance of a newly developed quenched and tempered High Strength Low Alloy (HSLA) steel. K-TEN8OCF, is researched. Using the Tekken self-restraint weld cracking test and Gas Metal Arc (GMA) welding, the new steel is compared against two commonly used high strength steels at various preheat levels. An investigation is made into the possible impacts of the cracking test results, based particularly upon the survey of practices. The steel test plates were subjected to X-ray, dye penetrant, and macroscopic and microscopic examinations to determine the extent of any existent cracking. It was found that the HBLA steel exhibited an excellent resistance to cracking, even when welded without the use of preheat; whereas, the T-1 and HY-80 steels had to be preheated in order to ensure cracking did not occur.

Available in PDF, EPUB and Kindle. Book excerpt: Description and results of test for detection and measuring of underbead cracks in welding of high-tensile steels and the effects of chemical and physical properties and welding conditions upon the formation of the cracks. It was found that cracking increased with thickness up to about one inch, and then decreased with further increases in thickness. Cracking also increased with increase of carbon and manganese. No correlation was observed between cracking and tensile strength, plate hardness, and heat input within the welding ranges used. (Author).
