鍛件的可焊性是指金屬材料在一定的工藝條件下，通過焊接形成優(yōu)質(zhì)接頭的性能，分為工藝可焊性和使用可焊性兩類。
工藝可焊性：主要指在一定的焊接工藝條件下，獲得優(yōu)質(zhì)焊接接頭的難以程度，即鍛件金屬材料對形成焊接缺陷的敏感性。
使用可焊性：主要指金屬的焊接接頭對使用要求的適應性和安全性，包括焊接的機械性能，耐腐蝕性能等。
影響因素：
鍛件材料因素：它既包括鋼材本身的化學成分，又包括所選用的焊接材料的化學成分（包括焊條、焊絲、焊劑、保護氣體等）。鋼材焊接性能的好壞主要取決于它的化學成分組成。而其中影響較大的是碳元素，也就是說金屬含碳量的多少決定了它的可焊性。
工藝因素:它包括從選擇焊接方法和制定合理的工藝措施兩個方面來影響焊接性。
構件類型因素：它包括焊接結構和焊接接頭的形式，剛度及應力狀態(tài)等，其將直接影響接頭的力學性能及產(chǎn)生缺陷的傾向。
使用要求因素：就是焊接結構的使用條件對焊接性的限制。它包括結構在高溫、低溫下、在腐蝕介質(zhì)中，在動、靜載荷交變載荷等條件下工作時，對焊接性的限制。
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.
Influencing factors:
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.
