Melting point: about 380Celsius (720)
Diameter: 1.6mm
Length: 50cm
Features: fusion core electrode, no need for solder powder, easy to melt
Application: Welding of stainless steel, aluminum, iron, refrigerator, air conditioner and other metals.
Low temperature aluminum welding wire can weld almost all white metals, including aluminum, aluminum alloys, cast aluminum, aluminum-magnesium alloys and dissimilar welding between the above metals, even for white metals that have been severely corroded or polluted by oil, even those that are considered irreparable. Aluminium alloys can be repaired. It is suitable for all-round welding of primary welding operators, and only needs a small heating device. The strength of the weld after welding is generally higher than the strength of the base metal itself, and it is enough to know the gas welding operation.
Instructions for use of low temperature aluminum welding wire
Steps
Step 1: Polish the surface by physical cleaning.
Step 2: Heat the surface of the base metal at the welding place until the temperature reaches the working temperature of the welding wire of 380-400Celsius, so that the welding seam can be formed by the heat conduction of the base metal and the molten welding wire. Do not use flame to burn the welding wire, and only when the parent When the surface temperature of the material is sufficient, the welding wire can flow and penetrate well into the metal capillaries.
step 3:
When repairing relatively thin aluminum, as long as the aluminum base material is heated to a suitable working temperature, and then the welding wire is rubbed back and forth to form the weld, and only the molten welding wire is used to fill the weld to form the weld.
Four steps:
Small pieces are welded with propane gas, large pieces are welded with industrial gas or induction heating device, and naturally cooled slowly after welding
Precautions:
The thicker the part, the more troublesome it is to heat, so it is very important to use a reasonable heat source. As long as the surface temperature of the base metal reaches the working temperature of the welding wire, the welding can be carried out. When oxyacetylene welding is used, neutral flame welding is used, but Do not burn the wire directly with fire
Applicable heat source: It can be used for many kinds of heat sources, such as propane, oxyacetylene, etc.
Storage: placed in a ventilated and dry place, it can be stored for a long time
Operation attention to detail
1. The surface of the base metal must be cleaned. Clean and Solder
2. The temperature of the base metal must reach 400Celsius , including the temperature of the base metal during the welding process, and the temperature should be kept at 400Celsius , and the temperature can be high or not low.
3. It is taboo to deliberately burn the welding wire with flame. After the base metal temperature reaches 400Celsius , the welding wire will naturally melt by the heat conduction of the base metal.
