| Abstract: | High-strength steels are applied extensively in the coal machinery industry.The test of weld cracks on Y groove is a more restricted test method for cold cracks checking the root cracks for HAZ of butt joints.The welding performances of the plate are determined by welding crack test,which provides the basis for setting reasonable welding process. |
