Abstract
The utility model discloses a welding groove of a stainless steel and carbon steel composite plate. The welding groove is characterized in that three sides of the welding groove form an open groove, the bottom side is connected with the two lateral sides in an arc smooth transition mode, the bottom side and the two lateral sides are respectively three tangents of an identical circle, and the length of the bottom side is the same as the radius of the inscribed circle. According to the specifications of a carbon rod used, the radius of the transitional arc is generally 3-5mm. According to the welding groove, the machining difficulty is reduced, the operation is simple, the manufacture process is simplified, the labor intensity of workers is reduced effectively, under the condition that the quality of products is ensured, the manufacture efficiency is promoted, and the manufacture cost is reduced. Particularly, the preparation efficiency of the welding groove of the composite plate of a coating thickness larger than or equal to 2mm is very high, and the welding groove is also suitable for a base layer of carbon steel material.
Description
Technical field
The utility model relates to the groove preparation of stainless steel+carbon steel composite board (hereinafter to be referred as composite plate) welding lamination defect and butt weld, is specifically related to a kind of stainless steel+carbon steel composite board bevel for welding.
Background technology
The demand that improves constantly oil along with China's industrial production force level in recent years is doubled and redoubled, and has driven the develop rapidly of petrochemical industry industrial chain.Because China's freshwater resources are relatively deficient, the ocean is a huge water source, has driven thus the development of desalinization industry.No matter be that petrochemical industry or desalinization industry all will be used corrosion resistant stainless steel, and if purely use stainless words, cost is very high, arises at the historic moment so namely satisfy the composite plate that requirement of strength satisfies again corrosion-resistant condition.The preparation technology of the weld groove of stainless steel+carbon steel composite board produces thereupon, but is subjected to the restriction of production site, equipment, operating condition etc. due to the preparation of groove, prepares more difficult.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of stainless steel+carbon steel composite board bevel for welding, use the method preparation of gouge+polishing, be particularly suitable for coating in irregular shape and be the not groove of junction and butt weld of 2mm and above composite plate, not only can reduce costs, reduce operator's labour intensity, and simplify work flow, improve production efficiency, guaranteed product quality.
The technical solution adopted in the utility model is: a kind of stainless steel+carbon steel composite board bevel for welding, it is characterized in that: this bevel for welding forms uncovered groove by three limits, base and two hypotenuses join with the form of circular arc rounding off, base and two hypotenuses are respectively three tangent lines of same circle, and the length on base is identical with the radius of this inscribed circle.
In such scheme, the radius of described inscribed circle is 3 ~ 5mm.
Due to the composite plate scrambling of land shape not, make the preparation of composite plate welding groove very difficult, only very large with sanding machine grinding labour intensity, and noise surpasses 100 decibels, and long working is very large to the human injury.The stainless steel that the utility model provides+carbon steel composite board bevel for welding is: according to the characteristic of metallic conduction, utilize electric energy extremely liquid METAL HEATING PROCESS, then by pressure-air, liquid metal is blown off, to realize the quick preparation of groove.The stainless steel of employing the utility model design+carbon steel composite board bevel for welding, effectively shortened the preparation time of groove, although noise injury is also arranged during gouge, but relative electric angle grinder, the noise of gouge is much smaller, in addition the working time short, improved production efficiency, improved worker's working environment.
According to the specification of use carbon-point, the radius of junction, three limits of this bevel for welding circular arc is generally 3 ~ 5mm, in practical operation, can widen as required and deepen operation to stainless steel+carbon steel composite board bevel for welding.
The stainless steel that the utility model provides+carbon steel composite board bevel for welding has reduced difficulty of processing, and is easy and simple to handle, simplified production procedure, effectively reduced worker's labour intensity, in the situation that guarantee product quality, reduce production cost, improved production efficiency.Especially the preparation efficiency for the bevel for welding of the composite plate of coating thickness 〉=2mm and basic unit thereof is very high.
Below in conjunction with drawings and Examples, the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is the base, and 2,3 is hypotenuse.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of stainless steel+carbon steel composite board bevel for welding, it is characterized in that: this bevel for welding forms uncovered groove by three limits, base 1 and two hypotenuses 2,3 join with the form of circular arc rounding off, base 1 and two hypotenuses 2,3 are respectively three tangent lines of same circle, and the length on base 1 is identical with the radius of this inscribed circle.In the present embodiment, the radius of described circular arc is 5mm according to the specification of use carbon-point section bar, and the radius of described inscribed circle is 5mm.
The concrete preparation method of the bevel for welding of stainless steel+carbon steel composite board is: (1) connects airline hose on air compressor, airline hose connects air purifier, air purifier act as the impurity of removing in compressed air, in order to avoid cause the obstruction of burning torch venthole, regularly for air purifier discharges water, avoid because dilutional hyponatremia causes electric shock accidents, particularly cause water freezing period at low temperature, more should in time discharge water, avoid ice crystal to stop up venthole.Air purifier is connected by the air admission hole of gas conduit with the carbon arc air gouging torch, makes at last that air compressor and external power source are firm to be connected.Select the electric welding machine of 0 ampere to 500 amperes of current range, the welding machine earth connection is wanted firm ground connection, and the wire of exporting from electric welding machine connects the carbon arc air gouging torch, and welding machine reliably is connected with external power source.(2) debugging of equipment: open air compressor and make the circulation of air of carbon arc air gouging torch gas outlet smooth and easy, gas pressure satisfies the needs that blow down liquid metal and get final product (being generally 5-10 atmospheric pressure), opens welding machine and the carbon arc air gouging torch is switched on can begin operation.(3) first each 200mm scope plate face spray of both sides prevents splash agent to groove; the purpose that spray prevents splash agent is to prevent that liquid metal is bonded on the plate face; can protect with refractory material the plate face that does not have spray to prevent splash agent the plate face is demanding, prevent the oxidized metallic pollution plate face that splashes.(4) select the carbon-point of suitable specification to carry out gouge according to the size that will prepare bevel for welding, during gouge, the gouge direction towards gouge metal one side not, makes as far as possible the gouge metal drop on and sprays in the zone that prevents splash agent.(5) the complete groove of gouge is polished to exposing metallic luster, the poisonous metal oxidized to remove, that carburizing is polluted with electric angle grinder.(6) groove prepares the complete weld job that carries out.
