Abstract

The utility model discloses a metal particle reinforcing flux-cored aluminum welding wire which comprises a welding wire body. The welding wire body consists of an aluminum-silicon alloy sheath and a powder core filled in the sheath. The thickness of the sheath is 0.2-0.7mm, and the diameter of the power core is 0.6-1.6mm. The metal particle reinforcing flux-cored aluminum welding wire has the advantages of being simple in structure and strong in adaption. When the thin sheath and the thin welding wire body are used for welding a thin aluminum alloy workpiece, the welding wire has good wettability and fluidity, welding wire manufacture materials are saved, weld joint toughness is improved, and weld joint strength is improved.

Description

Metallic particles strengthens explosive core aluminium welding wire

Technical field

The utility model relates to flux-cored wire, especially relates to a kind of metallic particles and strengthens explosive core aluminium welding wire.

Background technology

The weldability of alusil alloy, wetability and mother metal color consistency, plating, strength of joint and corrosion resistance are all splendid, are argon arc welding and brazed aluminum alloy good welding materials commonly used.But because drawing adds the problems such as man-hour is easily broken, welding wire can only drawing be worked into Φ 1mm, is difficult to be processed into the high flux-cored wire of thinner silicon content, causes the intensity of weld seam lower than the intensity of mother metal.

Summary of the invention

The purpose of this utility model is to provide the metallic particles that a kind of diameter is thin and the scope of application is larger to strengthen explosive core aluminium welding wire.

For achieving the above object, the utility model can be taked following technical proposals:

Metallic particles described in the utility model strengthens explosive core aluminium welding wire, comprises the welding wire body, and described welding wire body is comprised of alusil alloy crust and the powder core that tamps in it, and the thickness of described crust is 0.2-0.7mm, and the diameter of described powder core is 0.6-1.6mm.

The utility model has the advantage of simple in structure, strong adaptability.Thinner crust and thinner welding wire body are when the thinner Al alloy parts of welding, and welding wire has good wetability and mobility, has saved the welding wire manufactured materials, has improved the toughness of weld seam, has increased the intensity of weld seam.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, metallic particles described in the utility model strengthens explosive core aluminium welding wire, comprise the welding wire body, this welding wire body is comprised of alusil alloy crust 1 and the powder core 2 that tamps in it, wherein the thickness of crust 1 is 0.2-1.5mm, and the diameter of powder core 2 is 0.6-1.6mm, makes the thinnest diameter of finished product welding wire body only be 1mm, satisfy the welding of thinner Al alloy parts, improved intensity and the toughness of weld seam.

Claims (1)

1. a metallic particles strengthens explosive core aluminium welding wire, comprise the welding wire body, it is characterized in that: described welding wire body is comprised of alusil alloy crust (1) and powder core (2) of tamping in it, and the thickness of described crust (1) is 0.2-0.7mm, and the diameter of described powder core (2) is 0.6-1.6mm.
