Contrast Studies on Properties of GXHJ-1 and SJ101 Sintered Weld Agents

To get a property comparison of GXHJ-1 sintered welding agent with SJ101 sintered welding agent, related tests were carried out, including deposited metal test, lab butt-joint plate test, single-welding stick operation test, double-welding stick operation test as well as operation test with H08C welding stick, focusing differences of the two in terms of technological properties and weld seam impact toughness. The result of deposited metal test shows that the two welding agents are almost the same in technological property and mechanical property; the results of lab butt-joint plate test and single-welding stick operation test show that SJ101 is better than GXHJ-1 in technological property, and that the two are similar in weld-seam impact toughness; and the results of double-welding stick operation test show that GXHJ-1 is better than SJ101 in both technological property and weld-seam impact toughness.
