The procedure of gas-metal arc welding (GMAW) has received much attention in recent years and has numerous beneficial applications in the industry. The arc voltage, welding current and welding speed are three independent variables of this process that may affect the mechanical properties of the weld metal. As one of the most important mechanical properties of the weld metal, we can mention its yield strength and ultimate tensile strength. Therefore, we focus on the strength of the weld metal in CK45 carbon steel welded by the robotic GMAW process under different conditions. The accumulated results clearly illustrate that the strength of the weld metal is a monotonic function of the variables of welding.

CK45碳钢焊缝金属的机械强度

近年来,气体保护焊(GMAW)工艺受到了广泛关注,并在工业中有许多有益的应用。电弧电压、焊接电流和焊接速度是该过程的三个独立变量,可能会影响焊缝金属的机械性能。作为焊缝金属最重要的机械性能之一,我们可以提到它的屈服强度和极限抗拉强度。因此,我们重点研究了机器人 GMAW 工艺在不同条件下焊接的 CK45 碳钢中焊缝金属的强度。累积结果清楚地表明,焊缝金属的强度是焊接变量的单调函数。
