3.2mm 4.0mm Pure Aluminum Welding Rod Electrode Shielded Metal Arc Welding

  
Name: AL109, pure aluminum electrode. Standard: GB / T3669E1100 AWS A5.3E1100. Description: AL109 is pure aluminum welding with salt type coating, its welding joint is not strong, but good at corrosion resitance. It is applied to the aluminum and aluminum alloy welding which is not be requested strong. Adopt dc power source, electrode connected positive, short arc and rapid welding. Usage: mainly used to weld aluminum, pure aluminum containers. Standard: GB / T3669E4043 AWS A5.3E4043.

AL209 is aluminum silicon welding with salt type coating, good anti-thermal cracking performance, weld joint with a certain mechanical properties. Large versatility, for poor solderability aluminum alloy, it is also not easy to form cracks. Using DC power source, electrode connect with positive, adopt short arc and rapid welding. Usage: commonly used in aluminum, aluminum and silicon castings, general aluminum and forged aluminum, hard aluminum welding, not welding aluminum-magnesium alloy. Name: AL309, aluminum manganese electrode.

Standard: GB / T3669E3003 AWS A5.3E3003. AL309 is aluminum manganese welding with salt type coating. Its function is high welding strength, corrosion resistance is similar to aluminum.

For welding aluminum-manganese alloy, aluminum and other aluminum alloy. Usage: used for welding aluminum-manganese alloy, aluminum and other aluminum alloy welding.

Name: AL409, aluminum and magnesium electrode. Standard: GB / T3669E5183 AWS A5.3E5183. AL409 is aluminum magnesium welding with salt type coating. It is suitable for welding magnesium cating and forging aluminum alloy, high strength, good malleable, good corrosion resistance.

Usage: used for bicycles, aluminum scooters and other sports equipme. Nt, locomotive, chemical pressure vessels, ordnance production, shipbuilding, aviation and other industries of aluminum and manganese alloy welding. 1, the electrode is extremely vulnerable to moisture, it should be stored in a dry sealed container, to prevent moisture deterioration. 2, before welding the electrode at about 150?

3, welding should be used pad, and according to the thickness of the welding pieces heated to 200-300? Welding process, the electrode is not horizontal swing to improve the welding speed, the electrode should be vertical welding surface, arc should be as short as possible. Replacement of the electrode must be carried out quickly.

4, welding parts in the welding must be removed before the oil, impurities. After welding should be carefully removed slag, and washed with steam or hot water clean.
