Lamelar tearing
TīmeklisTherefore in this paper, the cause of lamellar tearing occurrence is investigated by conducting various tests in which the lamellar tearing was reproduced experimentally and also a study is made as regards the material selection and welding procedure for preventing this type of cracking. Tīmeklisabout lamellar tearing for anyone concerned with. welded steel fabrications. A description of lamellar. tearing is given and the causes of the cracking. briefly discussed in metallurgical terms. The practical. occurrence of the problem with respect to both joint. design and structure types is discussed in some.

As restraint will contribute to the problem, thinner section plate which is less susceptible to tearing, may still be at risk in high restraint situations.
