Introduction and use of ER4043 aluminum welding wire
Latest company news about 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.

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.
