secondary oxidation of molten steel
Secondary Oxidation of Steel
Secondary oxidation is a common phenomenon in the processing of steel. It refers to the oxidation process in which steel is corroded and reacts with oxygen in the air after being heated to an elevated temperature. At present, the secondary oxidation of steel mainly oc......
Cutting of high-strength steel - hard alloy for cutting high-strength steel
Cutting Process of High Strength Steel
High strength steel (HSS) is a type of steel with high tensile strength and hardness properties, which makes it an ideal material for components and parts used in a wide range of engineering applications. It is known to be stronger, more rigid and held to hi......
Features of multi-layer multi-pass welding
Introduction
Multi-layer and multi-pass welding procedure is one of the most common methods used in the fabrication of industrial welded products. It is also known as incremental welding and involves the formation of multiple weld beads in a single weldment. The purpose of the multiple weld beads ......
Transition Coefficients of Weld Alloying Elements
Introduction
The transition coefficients of welded alloy elements refer to the degree of change of the properties of the welded alloy elements between the welded zone and the base material. It is an important physical parameter in the welding surgery. It is one of the main indicators to evaluate......
Types of arc welding power sources and their scope of application
Arc welding power source
Arc welding is a metal joining process by which two pieces of metal are fused together by the application of a high current electricity. Arc welding is one of the most popular and efficient methods of joining metal together and can be used for a variety of processes. To p......
