High quality aluminum welding wire manufacturer from China

At present, the production processes of aluminum welding wire rods  roughly divid into vertical semi-continuous casting-extrusion method. Continuous casting  direct rolling method. Horizontal continuous casting method. Today we mainly talk about continuous casting  direct rolling method.

Continuous casting  direct rolling process (referred to as CCDR) is a world-leading production process. The production process is batching → melting → refining → continuous casting (diamond blank with a side length of 40-50mm) → Hot continuous rolling (13 passes) → Υ9.8mm aluminum rod wire blank. The biggest difference between the aluminum welding wire produced by this process and current domestic horizontal continuous casting process is that the continuous casting and direct rolling wire has higher density, lower hydrogen content, more dense uniform welding wire. Meanwhile the mechanical properties are more stable.

For example

Take ER5356 aluminum welding wire as an example. The ER5356 aluminum welding wire made by continuous casting  direct rolling process compared with horizontal continuous casting. The welding wire is compared and analyzed in terms of appearance quality, gas elements, alkali metal content, microstructure and mechanical properties. The results show that the continuous casting and direct rolling of ER5356 aluminum  wire rod has better metallurgical quality than that of horizontal continuous casting aluminum welding wire.

The content of gas elements  alkali metals is lower than horizontal continuous casting aluminum welding wire. The hydrogen and oxygen content are the same 1/3. With fewer defects such as blowholes  slag inclusions.  The strength and plasticity are higher than those of horizontal continuous casting and continuous drawing rods.  The surface quality and welding process performance of aluminum welding wire prepared by continuous casting and direct rolling rods are better than horizontal continuous casting and continuous drawing . The strength and elongation of the welding wire and the deposited metal of the wire are better than those of the horizontal continuous casting and continuous drawing aluminum welding wire. There are more pores in the horizontal continuous casting  continuous drawing welding wire.
