Notice items
1).Before welding, the oxide film and oil on the welding edge of the workpiece should be strictly removed, otherwise it will cause poor fusion of the weld and cause defects such as pores and slag inclusion.
2).It is necessary to preheat with 400-500℃ before welding.
3).In order to ensure welding penetration without collapse, welding brackets can be used to hold molten metal.
