2.5 what is the current of the welding rod sheet?
The main specifications of manual arc welding are welding current, welding rod diameter and welding layer.1) welding rod and current matching parameterWelding rod diameter 1.6, 2, 2.5, 3.2, 4, 5, 5.8Current (A) ranged from 25~4040 to 6050~80100 to 130160~210200 to 270260~300Note: welding current should be 10% to 20% smaller than usual when vertical welding, horizontal welding and overhead welding.2) the diameter of the electrode and the diameter of the electrode are usually selected according to the thickness of the component and the position of the welding. When the welding electrode diameter can choose some welding when the electrode diameter is less than 5mm, and the maximum overhead welding horizontal welding electrode diameter is 4mm, and the first layer of multilayer welding groove weld using electrode diameter is 3.2 ~ 4mm.Selection of electrode diameterWelding thickness (mm) of 2336 ~ 12 = 13Electrode diameter (mm) 23.2, 3.2 ~ 44~54 to 6
Welding rod with a diameter of 2.5 mm, theoretical welding current amperage is between 50~80. The thin plate shall match the welding current according to different welding positions. The welding current selection range is as follows:According to different welding position, match different welding current.Flat position: 60A~80A.Vertical welding position: 50A~70A.Horizontal welding position: 50A~60A.Overhead welding and elevation welding position: 50A~65A.According to the specific choice of plate thickness, welding arc welding even broken.
Welding sheet iron generally use 43 kg class acid electrode J422, current in 80-100A, welding thin sheet iron current should not be too small, the current is too small, but easy to weld through.
