Then the damage caused by welding spatter in Q345B square tube welding is mainly manifested in: reducing welding deposition and high efficiency, reducing welding production efficiency;Spattering is easy to adhere to welding parts and nozzles, knowledge of the advantages and disadvantages of Q345B cold square tube affects welding quality, the spatter of the precision seamless tube increases sharply and the particles are large,ហើយប្រព័ន្ធដែលមិនប្រាកដស្រាកដប្រាកដបង្ហាញការរចនារូបរាងដែលមានរូបរាងស្រាកដើម្បីជៀសវាងការលាក់ដែលបានធ្វើឲ្យប្រភេទ ៥ខាងក្រោមគួរជួយអ្នកទៅកន្លែ
(1) In Q345B square tube arc welding, there is a certain regularity between the splash rate of each diameter electrode and the welding current: the splash rate is lower in the small current area, and the splash in the high current area The ejection rate is also small, and the spattering rate in the middle area is larger.ដូច្នេះនៅពេលជ្រើសចំនួននៃការស្វែងរកបច្ចុប្បន្ន ព្យាយាមជៀសវិញផ្ទៃដែលមាន
(2) ការពង្រីកខាងក្រៅនៃអេឡិចត្រូដគួរត្រូវបានពង្រីកអប្បបរមាដែលអាចបន្ថយ
