Abstract

Disclosed is an arc plastic welding rod, which is that a solid bar-shaped structure which is formed by a circular arc face of upper camber is arranged on a plane. Compared with the existing plastic welding rod, the superiority of fillet weld combination remains; when the plane is welded, contact surface is large, combination is firm, loading capacity of fillet weld is large, and the utility model is used conveniently; the upper camber of an arc face and the width of the plane can be regulated according to the strength, the thickness and the width of welds of a welded base material; redundant projecting parts of both sides of welds are avoided at a welding part; the utility model has the advantages of material saving, smoothness and beautiful appearance.

Description

The arc plastic welding rod

The utility model relates to a kind of plastic welding rod.

Existing plastic welding rod has circular and flat (∞).Circular welding rod is applicable to the welding of angle welding and downhand weld, and weak point is that it is attractive in appearance that unnecessary cambered surface protuberance position influence is left in the weld seam both sides; Moreover when carrying out the plane welding, welding rod belongs to the inclined-plane with the plane and combines, and has influenced the adhesion of commissure.The intermediate recess of flat welding rod part is just corresponding to the strongest stressed position on the mother metal bonding crack vertical plane, and stressed cross section is just being reduced at the depression position, has fault of construction, and the weld seam both sides still exist arc to give prominence to the position, influences attractive in appearance.The flat welding rod does not fit into welded corner joint.

The purpose of this utility model is to overcome the weak point that the prior art plastic welding rod exists, and a kind of plastic welding rod of new planform is provided, and not only be applicable to angle welding, downhand weld, and the commissure slyness is attractive in appearance, and in conjunction with firm, holding capacity is strong.

Arc plastic welding rod of the present utility model, the cross section that it is characterized in that plastic welding rod is an arcwall face.

The plastic welding rod of the above is the solid stripe structure that the arc surface formation of a camber is arranged on a plane.Intensity, thickness, weld width according to welding base metal are adjusted cambered surface camber and plane width, adapt with the dynamics that requires that reaches stressed cross section of welding rod and welding base metal.Than broad, then the plane of welding rod is suitably widened as strength of parent height or weld seam, the camber height, and cambered surface is thicker, increasing contact-making surface, in conjunction with firmly, the increase holding capacity.Weld thin plate for another example, the camber of welding rod can be smaller, the welding slab, and the camber of welding rod can be bigger.

Description of drawings below in conjunction with embodiment:

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

Fig. 2 be the utility model and plane weld seam in conjunction with schematic diagram;

Fig. 3 be the utility model and right angle weld seam in conjunction with schematic diagram;

Fig. 4 be circular welding rod and plane weld seam in conjunction with schematic diagram;

Fig. 5 be flat welding rod and plane weld seam in conjunction with schematic diagram.

Among the figure: 1 arc plastic welding rod, 2 plane weld seams, 3 right angle weld seams, 4 circular welding rod 5 flat welding rods

Circular welding rod 4 and flat welding rod 5 are the shape of prior art, as with the contrast of Fig. 2, Fig. 3.

The utility model compares with existing plastic welding rod, kept angle welding in conjunction with the time superiority, when welding on the plane, contact-making surface is big, and in conjunction with firm, the holding capacity of weld seam is big, use more conveniently, and can adjust cambered surface camber and plane width according to the intensity of welding base metal, thickness, weld width.Weld has been avoided the unnecessary ledge in weld seam both sides, has both saved material, and slick and sly again attractive in appearance, the profile of weld seam can be equivalent to the profile of metal solder.

Claims

1, a kind of arc plastic welding rod, the cross section that it is characterized in that plastic welding rod is an arcwall face.

2, welding rod according to claim 1 is characterised in that welding rod is the solid stripe structure that the arc surface formation of a camber is arranged in the plane.
