Abstract

The utility model discloses a tuna seine boat composite board welding structure which comprises a base layer (1) made of carbon steel, and a composite layer (2) made of stainless steel. The thickness of the composite layer (2) is L. The thickness ratio of the base layer (1) to the composite layer (2) is 10: 3. The tuna seine boat composite board welding structure is characterized in that a V-shaped beveled opening (5) is formed in one side of the base layer (1). The range of the opening included angle of the V-shaped beveled opening (5) is from 45 to 50 degrees. A transition layer welding seam (3) is arranged below the V-shaped beveled opening (5). The thickness of the transition layer welding seam (3) is 0.5L. The width of the transition layer welding seam (3) is the same as that of a composite layer welding seam (4) in the composite layer (2). The transition layer welding seam (3) is communicated with the composite layer welding seam (4). The width of the composite layer welding seam (4) is from 0.2L to 0.3L. The tuna seine boat composite board welding structure is simple in structure, ingenious in design, attractive in welding seam forming appearance, small in repair quantity and high in corrosion resistant capacity of the composite layer.

Description

Tuna seine ship composite plate welding structure

Technical field

The utility model is related to a kind of composite plate welding structure, particularly a kind of tuna seine ship composite plate welding structure.

Background technology

In the manufacture of foreign-going ship, can possess erosion-resisting performance to allow hull, generally require to use composite, particularly outer layer to be the composite of stainless steel to make the housing of ship.Tuna seine ship is exactly to need to meet a kind of ocean fishing vessel for fishing for tuna of above-mentioned condition, and this tuna seine ship needs to use the composite board that basic unit is carbon steel, cladding is stainless steel.And the mode of traditional this composite board of welding is that groove is opened up in cladding side, the leg of this mode is excessive, and unsightly, and repairing amount is larger, can waste stainless steel welding material for profile appearance of weld.Most importantly this mode is very big due to the contact area of basic unit and transition zone, so welding process moderate resistance eroded elements Gr can be substantial amounts of excessively into basic unit's welding bead, the resistance to corrosion that Gr elements in cladding excessively into the weld seam of transition zone, can then ultimately result in cladding declines.Therefore a kind of new composite plate welding manner or welding structure is needed to solve the above problems now.

The content of the invention

The utility model is that, in order to solve the above-mentioned deficiency present in prior art, proposition is a kind of simple in construction, designs ingenious, appearance of weld is attractive in appearance, and repairing amount is small, the higher tuna seine ship composite plate welding structure of cladding resistance to corrosion.

Technical solution of the present utility model is：A kind of tuna seine ship composite plate welding structure, including the cladding that the basic unit and stainless steel being made up of carbon steel are made, the thickness of cladding is L, and the thickness ratio of basic unit and cladding is 10:3, it is characterised in that：Double V-groove is offered in basic unit side, it is transition zone weld seam below 45-50 degree, double V-groove that the opening angle scope of double V-groove, which is, and the thickness of transition zone weld seam is 0.5L, transition zone weld seam and the composite bed weld seam being opened in cladding are wide and communicate, and the width of composite bed weld seam is 0.2L to 0.3L.

The utility model compared with the existing technology, has the following advantages that：

The tuna seine ship composite plate welding structure of this kind of structure type, its is simple in construction, design is ingenious, rationally distributed, it is directed in the composite board welding structure that traditional basic unit is carbon steel, cladding is stainless steel, and groove is opened up in cladding side, the leg of this mode is larger, its appearance of weld can be caused unsightly, repairing amount is larger, waste stainless steel welding material.And this mode can cause the resistance to corrosion of cladding to decline.For these reasons, the utility model devises a kind of new welding structure, this structure is mainly characterized by opens up groove in basic unit side, this structure is greatly reduced due to the contact area of transition zone and basic unit, the excessive of anticorrosive element Gr can be greatly reduced, so the resistance to corrosion of cladding can be greatly increased, welding quality is intact, and the requirement that long range fishing is welded to composite plate can be met completely.

Brief description of the drawings

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

Fig. 2 is the A portions enlarged drawing in Fig. 1.

Embodiment

Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1 and Figure 2：A kind of tuna seine ship composite plate welding structure, including the cladding 2 that the basic unit 1 being made up of carbon steel and stainless steel are made, the thickness of cladding 2 is L, and basic unit 1 is 10 with the thickness ratio of cladding 2:3, double V-groove 5 is offered in the above-mentioned side of basic unit 1, the opening angle scope of this double V-groove 5 is 45-50 degree, it is transition zone weld seam 3 at the closing in of double V-groove 5, the thickness of this transition zone weld seam 3 is 0.5L, and transition zone weld seam 3 and the composite bed weld seam 4 being opened in cladding 2 are wide and communicate, the width of composite bed weld seam 4 is 0.2L to 0.3L；

The welded advantage of tuna seine ship composite plate of the utility model embodiment is：Due in carbon steel（That is basic unit 1）Open one 45 degree to 50 degree of double V-groove, stainless steel in side（That is cladding 2）Simultaneously it is brought into close contact, the groove of such a form carries out gouge with carbon arc air gouging after basic unit is soldered from cladding side, digs a small u groove, carries out the welding of transition zone and cladding 2 again afterwards.The welding of such a groove type can make appearance of weld attractive in appearance, repairing amount is few, save the welding material of stainless steel, the welding of this opening, because transition zone and the contact area of basic unit 2 are greatly reduced, the excessive of anticorrosive element Gr can be greatly reduced, so the resistance to corrosion of cladding can be greatly increased, welding quality is intact.

Claims
