The welding of 1 and low-temperature M5 1 with M51f welding wire is operated at the working temperature of 179 degrees, and it has good affinity for welding materials, and is mostly used for welding under the conditions of extremely strict deformation control requirements or extremely thin.

2.WE53 low temperature aluminum covered electrode is used to weld seven series of aluminum alloys, and the welding temperature is 380-400 degrees. It has the advantages of no need to assist any flux welding during welding, preventing some flux residue during welding, having high welding strength, and being able to solve the welding of tertiary aluminum alloy with castings or die castings.

3.Q303 low-temperature aluminum welding wire also shows some special advantages for the weldability of aluminum alloy, that is, narrow gap welding with angle difference.
