Precautions for the preparation process of aluminum welding wire aluminum welding base material

Precautions for the preparation process of aluminum welding wire aluminum welding base material, in order to weld aluminum material, the welder must carefully clean the base metal, and use oil or solvent to remove any oxide and hydrocarbon contamination of the aluminum surface. The surface of the aluminum has an oxide ablation temperature of 3,700 degrees Fahrenheit, while the underlying aluminum base material ablate at 1200 degrees Fahrenheit. Thus, the appearance of any oxide remaining on the aluminum base material will restrict the penetration of the filler metal into the workpiece.


To remove the oxides on the surface of aluminum, you can use stainless steel wire brush or solvent corrosion. When using a stainless steel brush, it can only be removed in a fixed direction. Rough movements form oxide-embedded aluminum base metals. Together, use only stainless steel brushes on the exterior of aluminum. Do not use brushes that have been used on stainless steel or carbon steel. When using chemical solvents, be sure to clean the solvent before soldering.


Precautions for the preparation process of aluminum welding wire aluminum welding base material, to minimize the adverse effects of hydrocarbons by oil or solvent, and to use degreaser. Together make sure that the degreaser does not contain any hydrocarbons. Preheating aluminum workpieces can help avoid weld cracks. The preheating temperature should not exceed 230 degrees Fahrenheit. Use a thermometer to monitor the temperature to avoid overheating. In addition, the placement of continuous welds at the beginning and end of the weld zone can help to enhance preheating. The welder should also preheat a thick piece of aluminum while welding the thin material.
