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(jù)需要選擇圓筒或圓盤裝焊絲。為降低更換焊絲的頻率，機(jī)器人應(yīng)選擇桶裝焊絲，但由于采用桶裝焊絲，送絲軟管長(zhǎng)度大，阻力大，對(duì)焊絲挺度等質(zhì)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(wěn)定效率的優(yōu)點(diǎn)，而且具有很好的靈活性，即使在再?gòu)?fù)雜的環(huán)境中，也能保證焊接機(jī)器人穩(wěn)定、高能地運(yùn)行。它與設(shè)備的構(gòu)成密不可分，包括主體、焊接電源、一維重型滑臺(tái)、機(jī)器人L臂、清槍剪、控制系統(tǒng)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(xiàn)象是肯定會(huì)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(hù)氣體換成CO2含量少的混合氣，焊接出的氧化物就會(huì)少一些，黃色的斑就會(huì)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(zhì)量稍差的焊絲時(shí)，焊絲表面的鍍銅由于摩擦和脫落，會(huì)降低導(dǎo)管內(nèi)容積，高速送絲時(shí)阻力增大，焊絲無法平滑送出，產(chǎn)生的抖動(dòng)使電弧不穩(wěn)，從而影響到焊接質(zhì)量。嚴(yán)重者，發(fā)生卡死，使機(jī)器人停止運(yùn)轉(zhuǎn)，因此應(yīng)及時(shí)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.
