環(huán)縫自動焊接設(shè)備在焊接過程中不可避免會出現(xiàn)一些小失誤，那么如何防止呢？今天山東環(huán)縫自動焊接設(shè)備為大家介紹下：
It is inevitable that there will be some small mistakes in the welding process of the automatic welding equipment for girth seam, so how to prevent them? Today, the price of Shandong automatic welding equipment for circumferential seam is introduced to you as follows:
1、氣孔。在全位置焊中應(yīng)用自動焊接設(shè)備時，氣孔是一種比較常見的問題，導(dǎo)致該問題產(chǎn)生的原因有很多，比如焊材自身的原因、操作不當(dāng)、環(huán)境原因等。
1. Stomata. When automatic welding equipment is used in all position welding, air hole is a common problem, which is caused by many reasons, such as welding material itself, improper operation, environmental reasons, etc.
鑒于此，為有效地防止這一問題，在實(shí)施焊接時，應(yīng)加強(qiáng)氣體的保護(hù)，焊接溫度不可過高，嚴(yán)格按照比例以及相關(guān)要求來充裝氣體，確保充裝純度達(dá)到要求。同時還要注意施焊場地周圍的環(huán)境，若施工場地的風(fēng)速每秒超過8米，應(yīng)用防風(fēng)棚來實(shí)施防護(hù)，且環(huán)境濕度不可過大。此外，為確保施焊位置保持干燥，可利用環(huán)形火焰加熱器或中頻感應(yīng)加熱器來實(shí)施加熱。
In view of this, in order to effectively prevent this problem, in the implementation of welding, the gas protection should be strengthened, the welding temperature should not be too high, and the gas should be filled in strict accordance with the proportion and relevant requirements to ensure that the filling purity meets the requirements. At the same time, we should also pay attention to the environment around the welding site. If the wind speed of the construction site exceeds 8 meters per second, the wind shed should be used for protection, and the environmental humidity should not be too high. In addition, in order to keep the welding position dry, ring flame heater or medium frequency induction heater can be used for heating.
2、未熔合。環(huán)縫自動焊接設(shè)備在焊接過程中，未熔合這一問題一般常出現(xiàn)于立焊位置，導(dǎo)致該問題的原因有焊道打磨形狀不正確、在焊接時偏離焊縫或者焊槍擺動的寬度不夠合理等。鑒于此，在焊接過程中，在實(shí)施焊道打磨作業(yè)時，應(yīng)盡量打磨平整。
2. No fusion. In the welding process of automatic girth welding equipment, the problem of non fusion often occurs in the vertical welding position. The causes of the problem include incorrect grinding shape of weld bead, deviation from the weld during welding or unreasonable swing width of welding gun. In view of this, in the welding process, in the implementation of bead grinding operation, should try to smooth grinding.
同時在焊接之前，還應(yīng)對焊絲進(jìn)行仔細(xì)地觀察，察看其擺動寬度是否正確。此外，在焊接過程中，如發(fā)現(xiàn)焊接熔池和焊道中間出現(xiàn)偏離，應(yīng)及時實(shí)施調(diào)整，以免出現(xiàn)未熔合問題。
At the same time, before welding, the welding wire should be carefully observed to see if its swing width is correct. In addition, in the welding process, if there is deviation between the weld pool and the weld bead, it should be adjusted in time to avoid non fusion.
以上就是小編為大家介紹的如何防止環(huán)縫自動焊接設(shè)備的焊接失誤，希望為大家?guī)韼椭?/div>
