How thin is the smallest electrode?
The smallest electrode is the diameter of the electrode (mm) 1.6, the welding current (A) 25~40.
The most common electrode is 2.5mm. Hope to help you.
According to the national standard GB5117 "carbon steel welding rod" and GB5118 "low alloy steel welding rod" standard, the relevant models for the manual arc welding with carbon steel and low alloy welding rod are unified.E4313, for example, is a high titanium carbon steel electrode. The E said 43 electrode, said the tensile strength of the deposited metal is minimum, 1 said electrode for all position welding, the final 3 electrode is titanium calcium type, can be used in AC or DC positive and reverse welding power supply.According to the diameter of the welding rod, the diameter of the electrode depends on the thickness of the weldment. The current and diameter of the electrode are basically proportional to the diameter of the electrode.Electrode diameter (mm) 1.6, 2, 2.5, 3.2, 4, 5, 6.Welding current (A) 25~40, 40~65, 50~80, 100~130, 160~210, 200~270, 260~500.The most common ones are 2.5, 3.2, and 4 millimeters, 3.
