1、Non - alloy steel and fine - grain steel electrodes (with deposited metal tensile strength lower than 570MPa) are used for the welding of carbon steel and low - alloy steel.
2、When selecting electrodes, the chemical composition, mechanical properties, and crack resistance requirements of the steel are usually taken into account. At the same time, factors such as the shape of the welding structure, working conditions, stress conditions, and the performance of welding equipment must be considered.
3、Generally, for the requirements of good weld metal plasticity, high impact toughness, and good crack resistance, low - hydrogen type electrodes are selected.
4、For low - hydrogen type electrodes, they must be baked at 350 - 400°C for 1 hour before welding and used immediately after baking. Otherwise, defects such as pores, slag inclusions, and cracks are likely to occur.
5、Low - hydrogen type electrodes generally should not be baked repeatedly to prevent the coating from becoming brittle and falling off.
6、To ensure welding quality, the welding groove of the workpiece should be cleaned thoroughly. There should be no oil, rust, moisture, paint, or other contaminants. For the use of low - hydrogen...
