Knowledge of preventive measures for Q345B square tube welding spatter

Classificatione Q345B tubae quadratis ubiquitatis esse dicitur.Stainless steel sheet is indispensable in the construction industry.Knowledge of the advantages and disadvantages of Q345B cold drawn square tube and Q345B square tube is also one of the common raw materials in the basic construction of houses. Welding is a relatively common application processing method in stainless steel plates.What should we pay attention to when welding precision seamless pipes for Q345B square tubes?Splashing videtur aliquot ex problemis quae saepe occurrant in to to fermento.For Q345B square tubes Splashes during welding, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co., Ltd. How to prevent it?

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 facile est adherere partes et nozzles, scientiam avantiarum et defectum Q345B tubae frigidae quadraticorum dissipatae quadraticorum qualitatem ferentis influent, spatio tubae precision is sinensis acutis crescet et particulae magnae sunt,And the precision seamless tube causes the welding appearance design to be relatively unsmood and other shortcomings.Pro evadere dolores, sequentes quinque countermeasures vobis aliquid adiuvant:

(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.Therefore, when selecting the amount of welding current, try to avoid areas with high spattering current.

　　 (2) Exaltatio externi electrodi minimizabitur maxime possibilis, quod reddere potest spatio de fermento
