Dry Welding electrode Important to Welding Procedure

 The copper bus bars is essential to the welding procedure since the quality from the welding electrode can greatly affect the welding quality. The coating and also the performance from the copper clad aluminum produced by the welding electrode production line may be greatly influenced from the air moisture, administration methods, storage time, etc. The welding overall performance of bus bar manufacturers can be weakened because of to moisture absorption to cause arc instability, elevated spatter, air hole era, crack as well as other flaws, and therefore, it is very important to dry the electrode by using the welding electrode baking oven before using it.

The welding electrode has various chemical compositions and also the drying methods can be different. The welding electrode manufacturing facility suggests that the reduced hydrogen kind welding electrode which is also called as alkaline electrode ought to be baked by using the welding electrode drying oven prior to it is used, the drying procedure can reduce the hydrogen content material of the electrode in order to stop the issues of air holes and crack. The drying temperature of welding electrode oven ought to be set at 350??, the drying time ought to be about 1 hour to two hours, and the dried welding electrode should be saved within the warmth preservation space in the temperature of 50?? to 100?? for about 1 hour. The acid electrode has the drying temperature of 150?? to 250??, and it is ought to be dried for around one hour.

The drying of the electrode has special requirement the electrode should not be directly put into or taken from the higher temperature kettle so as to stop the problems of coating crack or peeling due to unexpected heating or cooling. Simultaneously, the electrode supplied by the welding electrode factory should not be stored inside a big bulk in order to let the moisture fatigued totally. The dried electrode should be saved in the drying oven so as to avoid secondary drying process because the alkaline electrode can lose its home because of towards the drying for several occasions.

If the electrode is saved for some time, and it consists of a great deal dampness, the electrode ought to not be utilized even it's dried because it can produce a lot air holes due to the rust problem of the ferric content material. The quality of the electrode is essential to make sure the welding high quality from the welding process, and therefore, it should be nicely saved and dried when it is used.
