锻件可焊性的影响因素 Influencing Factors of Weldability of Forging
Forging the weldability refers to the metal material in a certain process conditions, through the formation of high-quality joint welding performance, divided into two types of solderability and the use of solderability.
Process Solderability: mainly refers to a certain welding process conditions, access to high-quality welded joints difficult degree, that is, forging metal materials on the formation of welding defects of the sensitivity.
Use of solderability: mainly refers to the metal welded joints on the use of the requirements of the adaptability and safety, including the mechanical properties of welding, corrosion resistance and so on.
Forging material factors: it includes the chemical composition of the steel itself, but also the chemical composition of the selected welding material (including electrodes, welding wire, flux, shielding gas, etc.). The quality of steel welding depends mainly on its chemical composition and the most influential of which is the carbon element, that is, how much metal carbon content determines its solderability.
Process factors: it includes from the choice of welding methods and the development of reasonable technical measures in two ways to affect the weldability.
Component Type Factor: It includes the form of welding structure and welded joint, stiffness and stress state, which will directly affect the mechanical properties of the joint and the tendency to produce defects.
The use of requirements factors: the use of welding structure is the use of welding restrictions. It includes the structure at high temperature, low temperature, in the corrosive medium, in the dynamic and static load load and other conditions of work, the restrictions on the welding.
