First, argon arc welding, precision castings, alloy steel, stainless steel casting, aluminum alloy die castings with argon arc welding machine for welding repair.Part of the mould manufacturing and repair factory, also USES the welding repair mold defect.Advantages: welding repair of high efficiency, high precision of the electric welding machine.Wire sort is more, the most widely used on stainless steel, aluminum alloy products.Can be used for welding, high intensity of teaching.Disadvantages: used for defect repair, small defect fix (porosity, sand holes), because of the impact is too large, the molten pool line trace (bite edge phenomenon).Weld steel has a hard point.Due to thermal effects, non-ferrous casting or thin-walled weld repairs, easy to produce thermal deformation.Operating higher technical requirements.
Second, electric welding machine, cast iron, cast steel weld with traditional way.Advantages: repair defects, high efficiency.Disadvantages: solder joints on high hardness after welding, internal stress, prone to cracks, general need annealing heat treatment can meet the requirements of processing.And limit because of the welding condition, internal easy to produce the secondary defects such as porosity, slag.
Third, argon arc welding, precision castings, alloy steel, stainless steel casting, aluminum alloy die castings with argon arc welding machine for welding repair.Part of the mould manufacturing and repair factory, also USES the welding repair mold defect.Advantages: welding repair of high efficiency, high precision of the electric welding machine.Wire sort is more, the most widely used on stainless steel, aluminum alloy products.Can be used for welding, high intensity of teaching.Disadvantages: used for defect repair, small defect fix (porosity, sand holes), because of the impact is too large, the molten pool line trace (bite edge phenomenon).Weld steel has a hard point.Due to thermal effects, non-ferrous casting or thin-walled weld repairs, easy to produce thermal deformation.Operating higher technical requirements.
