What's the difference between two oxygen welding and common electrode welding? What are the advantages and disadvantages?
CO2 welding protective medium is CO2 and the protective effect of SMAW protection effect, SMAW protective medium for coating gas making slag material produced, the effect is not good CO2
Now, there are still two people suspected of welding costs?Do not know that science and technology is the primary productive force?!Said the first two welding material, welding wire electrode 8 dollars a kilogram, 6 yuan a kilo, looks cheap electrode.You have to see how much of the filler metal left in the weld after welding is equal to the price.1, the outside of the electrode coating, and finally the welding slag and protective gas, does not belong to the filler metal.2, each electrode has a welding rod head, at least 5 centimeters, have to throw away, does not belong to the filler metal.3, welding rod splash, splash of metal, does not belong to the filler metal.In addition, other costs, welding rod to dry, need oven, heat preservation barrel, heating electricity, throw away the welding rod.Let's talk about the same welding power, welding, welding heat input two is small, costs less power, more power inverter welder.What's more about efficiency and speed?.1, do not bake electrode, save time, minus a manual.2, do not change electrode, also need not from new arc, save time3, do not knock the welding slag off at least a coolie.4, for welding speed, two welding is three times of welding rod. (on this one, a welder can top three, you have to calculate how much money, artificial!)
