    deformation may occur and thus reduce the loader's bearing and operating capacity. The loader boom frame requires bearing some static and load loads when operating, so the welding area of the active arm and beam may have cracks or strength fracture under the cyclic load and load load, causing structural failure at last. The existing researches on the failure of loader boom are divided into two types: one is …
