Hand welding electrodes 3.2 and 4 which are more commonly used?
Personally think 3.2 is more commonly used.The welding between the sheet metal parts, the weld is not big, 4-5mm, 3.2 of the running better.For wider welds, 4 is recommended;
Hand welding electrodes 3.2 and 4 are more commonly used.
Electrode core diameter, that is to say, 3.2 of the electrode core is 3.2 millimeters in diameter, and 4 is 4 millimeters in diameter.The diameter of the welding rod is large, and the current should be larger when welding. High current, high efficiency, can be used in relatively thick plate welding. On the contrary, relatively thin plate welding, should choose a smaller diameter welding rod.Electrodes commonly used in three specifications, 3.2, 4, 5. Civil J422 and J506 more commonly used, industrial use of J507, J427 more. But the civilian use of 3.2 diameter more.
