Introduction and use of ER4043 aluminum welding wire

               Introduction and use of ER4043 aluminum welding wire

The ER4043 aluminum welding wire is a demanded product from the UAE customer. The required wire diameter is 1.2mm, which is the conventional aluminum wire size. This article introduces the ER4043 aluminum welding wire to the needs of UAE customers.
1.ER4043 aluminum welding wire introduction
ER4043 aluminum alloy has the characteristics of low melting point, good fluidity and good corrosion resistance. It is very beneficial to avoid welding cracks and is specially used as welding material. As a kind of versatile aluminum-silicon welding wire, ER4043 has good resistance to thermal cracking on deposited metal and can also guarantee certain mechanical ability.


2. ER4043 aluminum welding wire performance characteristics
ER4043 is a silicon-containing 5% aluminum-silicon alloy wire, also known as S311. It has good fluidity and is used for welding forged and cast materials because of its weak sensitivity to hot cracks. It is also used as a filling material for argon arc welding and brazing of aluminum alloy workpieces and castings other than aluminum-magnesium alloys. It is easy to form brittle Mg2Si in the weld during welding, which reduces the plasticity and corrosion resistance of the joint, so the wire is generally not used for welding aluminum-magnesium alloy. The welding is beautiful and the sightseeing is bright, the arc is stable, and the splash is small, but the color is different from the base material after the anodizing treatment.
The melting temperature of ER4043 ranges from 1065-1170oF, the color after anodization is off-white, and the low tensile strength is 186MP.

3.The chemical composition of the ER4043 aluminum welding wire is as follows:

4. ER4043 aluminum welding wire welding method and use
Welding method of ER4043: AC argon arc welding, pure argon gas protection. It is necessary to clean the workpiece weld before welding, and avoid air, weldment and welding wire damp.
Use of ER4043 aluminum welding wire: used for welding of 6601 series aluminum alloy, 3XXX series and 2XXX series aluminum alloy and cast aluminum. Widely used in ships, locomotives, chemicals, food, sports equipment, molds, furniture, containers, containers.


The above is an introduction to the performance characteristics, chemical composition and use of ER4043 aluminum welding wire. I believe that everyone has a certain understanding of ER4043 aluminum welding wire. It is widely used in our lives and it is also indispensable. At present, the demand for aluminum wire of our company is very large. In terms of products, some manufacturers in the market may have lower prices, but generally there will be some problems in the use process. Our company's aim is to insist on using quality to speak, to provide quality assurance and quality after-sales service.

How to start welding

How to start welding

Welding, also known as welding and splicing, is a manufacturing process and technique for joining metals or other thermoplastic materials such as plastics in a heated, high temperature or high pressure manner.
Metal welding, according to the characteristics of its process, there are three major categories of welding, pressure welding and brazing.


It is a method of heating the workpiece interface to a molten state during the welding process and completing the welding without pressure. During fusion welding, the heat source rapidly heats and melts the interface of the two workpieces to be welded to form a molten pool. The molten pool moves forward with the heat source, and after cooling, forms a continuous weld to join the two workpieces into one body.


Under pressure conditions, the two workpieces achieve atomic bonding in the solid state, also known as solid state welding. The commonly used pressure welding process is resistance butt welding. When the current passes through the connection end of the two workpieces, the temperature rises due to the large resistance, and when heated to the plastic state, the connection is integrated under the axial pressure.


The metal material having a lower melting point than the workpiece is used as a brazing material, and the workpiece and the brazing material are heated to a temperature higher than the melting point of the brazing material and lower than the melting point of the workpiece, and the workpiece is wetted by the liquid brazing material, filling the interface gap and realizing the atomic interaction with the workpiece. The method of mutual diffusion, thereby achieving welding.


The temperature of the molten pool directly affects the quality of welding, the temperature of the molten pool is high, the molten pool is large, the fluidity of molten iron is good, and it is easy to fuse. However, when the temperature is too high, the molten iron is easy to smash, and the back surface of the double-sided forming is easy to burn through. The weld is not difficult to control, and the joint plasticity is reduced, and the bending is easy to crack. When the temperature of the molten pool is low, the molten pool is small, the molten iron is dark, the fluidity is poor, and defects such as incomplete penetration, unmelting, and slag inclusion are easily generated.
The temperature of the molten pool is closely related to the welding current, the diameter of the welding rod, the angle of the welding rod, the burning time of the arc, etc. The following measures are taken to control the temperature of the molten pool for relevant factors.
