            焊接機器人對焊絲的質量要求是什么?

            要了解焊接機器人對焊絲的質量要求是什么,首先我們要知道這個黃色的東西實際上是焊絲和焊接母材中的雜質,主要是硅錳元素在焊接過程中高溫氧化跟保護氣體中的CO2發生化學反應,分解形成氧化硅、氧化錳形成的氧化物,有點像手工焊條焊接時的焊渣。盡管這些現象甚至可以用焊接機器人制造,但這些氧化物除了外觀上有一點瑕疵外,對焊接質量沒有任何不良影響,用刷子也可以輕松地將其清除。

            To understand the quality requirements of welding robot for welding wire, first of all, we should know that this yellow thing is actually the impurities in the welding wire and welding base metal, mainly the high-temperature oxidation of silicon and manganese in the welding process, which reacts with CO2 in the shielding gas and decomposes into oxides formed by silicon oxide and manganese oxide, which is a bit like the welding slag during manual electrode welding. Although these phenomena can even be made by welding robots, these oxides have no adverse impact on the welding quality except for a little defect in appearance, and can be easily removed by brush.
            可根據需要選擇圓筒或圓盤裝焊絲。為降低更換焊絲的頻率,機器人應選擇桶裝焊絲,但由于采用桶裝焊絲,送絲軟管長度大,阻力大,對焊絲挺度等質量要求較高。
            Cylinder or disc welding wire can be selected as required. In order to reduce the frequency of welding wire replacement, the robot should choose barreled welding wire. However, due to the use of barreled welding wire, the length of wire feeding hose is large, the resistance is large, and the quality requirements such as welding wire stiffness are high.
            它不僅具有高能率和穩定效率的優點,而且具有很好的靈活性,即使在再復雜的環境中,也能保證焊接機器人穩定、高能地運行。它與設備的構成密不可分,包括主體、焊接電源、一維重型滑臺、機器人L臂、清槍剪、控制系統等。
            It not only has the advantages of high energy rate and stable efficiency, but also has good flexibility. Even in the most complex environment, it can ensure the stable and high-energy operation of the welding robot. It is closely related to the composition of the equipment, including the main body, welding power supply, one-dimensional heavy slide, robot l-arm, gun cleaning shear, control system, etc.
            焊母金屬元素中有多少硅錳元素,這種現象是肯定會存在的,要減少這些氧化物,可選用含硅錳元素較少的焊絲,保護氣體換成CO2含量少的混合氣,焊接出的氧化物就會少一些,黃色的斑就會少很多。
            The phenomenon of how many silicon and manganese elements are in the parent metal elements of welding will certainly exist. To reduce these oxides, the welding wire with less silicon and manganese elements can be selected, and the shielding gas can be replaced with the mixture with less CO2 content, so that there will be less oxides and yellow spots.
            在鍍銅質量稍差的焊絲時,焊絲表面的鍍銅由于摩擦和脫落,會降低導管內容積,高速送絲時阻力增大,焊絲無法平滑送出,產生的抖動使電弧不穩,從而影響到焊接質量。嚴重者,發生卡死,使機器人停止運轉,因此應及時清理焊絲管。
            In case of welding wire with poor copper plating quality, the copper plating on the surface of the welding wire will reduce the volume in the conduit due to friction and falling off, increase the resistance during high-speed wire feeding, the welding wire cannot be sent out smoothly, and the resulting jitter will make the arc unstable, thus affecting the welding quality. In serious cases, the robot is stuck and stops running. Therefore, the welding wire pipe shall be cleaned in time.
