Looking for various types of welding rods and wires and what materials are suitable for welding? Ask

There are three classification methods for electrodes: classification according to the use of the electrode, classification according to the main chemical composition of the coating, and classification according to the characteristics of the slag after the coating is melted.

According to the use of welding rods, welding electrodes can be divided into: structural steel electrodes, heat-resistant steel electrodes, stainless steel electrodes, surfacing electrodes, low-temperature steel electrodes, cast iron electrodes, nickel and nickel alloy electrodes, copper and copper alloy electrodes, aluminum and aluminum alloy electrodes and special-purpose electrodes.

If classified according to the main chemical composition of the electrode coating, the electrodes can be divided into: titanium oxide electrode, titanium oxide calcium electrode, ilmenite electrode, iron oxide electrode, cellulose electrode, low hydrogen electrode, graphite electrode and salt-based electrode.

If the electrode coating is melted and the slag characteristics are classified, the electrode can be divided into acid electrode and alkaline electrode. The main components of acid electrode coatings are acid oxides, such as silicon dioxide, titanium dioxide, ferric oxide, etc. The main component of alkaline electrode coating is alkaline oxide, such as marble, fluorite, etc.

Summary. Article of JB T 4709-2000 "Welding Regulations for Steel Pressure Vessels": "The weld metal between carbon steel and low-alloy steel of different strength steel grades shall ensure mechanical properties, and its tensile strength shall not exceed the upper limit specified in the standard for base metals with higher strength".

From the perspective of weld strength matching, J427 is suitable for 20g, and J507 is suitable for 16Mn. However, the measured value of the tensile strength of the deposited metal of the same strength grade of the welding rod produced by the domestic welding rod manufacturers in most cases exceeds the nominal value required by the standard, so the measured value of the tensile strength of the deposited metal should be considered when selecting the welding rod according to the principle of strength matching, and the strength of the weld deposited metal is too high, which will cause the strength and plasticity of the weld and the base metal to mismatch, affecting the performance of the welded joint. In view of this situation, "low matching" is more respected in China, and it is relatively more reasonable to choose J427.

Dear, hello, 20g material can be used with J427 and J507 electrodes and wires.

However, the measured value of the tensile strength of the deposited metal of the same strength grade of the welding rod produced by the domestic welding rod manufacturers in most cases exceeds the nominal value required by the standard, so the measured value of the tensile strength of the deposited gold beam should be considered when selecting the welding rod according to the principle of strength matching. In view of this situation, "low matching" is more respected in China, and it is relatively more reasonable to choose J427.

Dinggong Machinery has many years of experience to answer for you: welding wire is used as a filler metal or as a wire welding material for conduction. In gas welding and tungsten gas arc welding, the welding wire is used as a filler metal; In submerged arc welding, electroslag welding and other MIG/MAG arc welding, the wire is both a filler metal and a conductive electrode.

The surface of the welding wire is not coated with anti-oxidation flux.

Describe several common types of welding wires:

1.Stainless steel welding wire: stainless steel solid core welding wire can be used for inert gas shielded welding (TIG, MIG welding). It can also be used for submerged arc welding. It can be divided into stainless steel solid core welding wire and stainless steel flux cored welding wire.

2.Aluminum-aluminum welding wire: also known as aluminum-aluminum flux-cored welding wire, so the welding wire can be used to weld aluminum and aluminum together.

3.Copper-aluminum welding wire: It is a flame brazing material.

4.Silver welding wire: it is in the production and maintenance of parts and components in the food industry; containers, pipes; electrical plugs; surgical equipment and ophthalmic equipment; Precision components used in the mechanical and electromechanical industries.

The material of the welding wire is mainly metal: tin.

Hello dear, I am glad to answer for you what is the material of the welding wire? A: Welding wire is actually a material we need to use when welding, this welding material is thinner than the welding rod, but the concealed touch is its conductivity and virtual is better than the welding rod. For example, the welding wire is made of metal materials, and other components are added to different types of welding wire.

However, there are many types of welding wires, such as the more common welding wires are stainless steel welding wires and non-ferrous metal welding wires, and their scope of application is different. We must choose the right welding wire when welding, so as to ensure that the connection is tight and not easy to break in the later stage.

Ding Gong Machinery has many years of experience to answer for you: welding wire is a filler metal or welding material that is also used as a conductive conductor. In gas welding and tungsten arc welding, the wire is used as a filler metal; In gas shielded welding such as submerged arc welding and electroslag welding, the welding wire is both a filler metal and a conductive electrode.

The surface of the welding wire is not coated with anti-oxidation flux. Introduce several common types of welding wire:1

Stainless steel welding wire: Stainless steel solid welding wire can be shielded with inert gas (TIG and MIG welding). It can also be used for submerged arc welding.

It can be divided into stainless steel solid core welding wire and stainless steel flux cored welding wire. 2.Aluminum-aluminum welding wire:

It is also known as aluminum-aluminum flux-cored welding wire. So this kind of welding wire got its name because it can weld aluminum and aluminum. 3.

Copper-aluminum welding wire: It is a flame brazing material. 4.

Silver welding wire: used in the production and maintenance of parts for the food industry; containers and pipes; electrical plugs; surgical equipment and ophthalmic equipment; and precision components used in the electronics industry.

There's a lot of variety. There are structural steel electrodes, heat-resistant steel electrodes, stainless steel electrodes, low-temperature electrodes, surfacing electrodes, etc. Each type of electrode is available in a variety of grades.

E indicates the number after the electrode indicates the tensile strength, the composition of the coating, the composition of the mixture in which the metal is deposited, and so on. There are specific criteria.

The material of the electrode and wire should be close to or slightly higher than the base metal, and the weldability should be good.

For workpieces or structures subjected to static load or general load, the electrode is usually selected according to the principle of equal strength of the weld and the base metal, that is, the tensile strength of the weld and the base metal is equal or similar. Welding rods are selected according to the working conditions and characteristics of the workpiece or welded structure.

For example, when welding workpieces bearing dynamic load or impact load, alkaline electrodes with high impact toughness of deposited metal should be selected, and acid electrodes can be selected when welding general structures. In order to ensure the performance of welded structures working in special environments, such as corrosion resistance, high or low temperature, etc., welding rods should be selected according to the principle that the properties of the deposited metal and the base metal are the same or similar.

As for what welding consumables to choose, you have to do welding process qualification, in principle, the chemical composition of the base metal and the welding consumables are similar, and the mechanical properties are similar, and in actual work, the mechanical properties of the welding consumables are slightly higher.

This question is very broad, and the purpose is to ask: how to choose welding rod and welding wire according to the material of steel.

1) The principle of equal strength, that is, the welding rod with the same strength grade as the base metal is selected. It is generally used to weld low-carbon steel and low-alloy steel.

2) The principle of the same composition, that is, the selection of electrodes with the same or similar chemical composition as the base metal. It is generally used for welding heat-resistant steel, stainless steel and other metal materials.

3) Principle of crack resistance Choose alkaline electrodes with good crack resistance to avoid cracks in the joints during welding and use. It is generally used for welding structures with large stiffness, complex shape, and dynamic load in use.

4) The principle of anti-porosity is limited by the conditions of the welding process, such as the inconvenience of cleaning the oil stain and rust of the weldment joint, and the acid electrode with strong porosity resistance should be selected to avoid the gas trapped in the weld during the welding process and the formation of porosity.

5) The principle of low cost Under the premise of meeting the requirements of use, try to choose welding rods with good process performance, low cost and high efficiency. The selection of welding rods should be based on the premise of ensuring the safety and feasibility of the welded structure, according to the chemical composition, mechanical properties, plate thickness and joint form, welding structure characteristics, stress state, structural use conditions on the requirements of weld performance, welding construction conditions and technical and economic benefits, etc., the welding rod should be selected in a targeted manner, and weldability test should be carried out if necessary.

Welding with argon arc welding, what kind of welding wire is used (material, thickness) I have the kind of welding white steel pipe for decoration A201 is a low-carbon CR18Ni12Mo2 stainless steel electrode with titanium coating. When welding, the coating has no redness, no.

The corresponding welding consumables are selected according to the strength of the steel.

1. The uses of the three are different:

1. The use of welding rods: in small or poor ventilation conditions, acid welding rods or low-dust welding rods should be selected. For structures with a large amount of welding workload, high-efficiency electrodes should be used as much as possible when conditions permit, such as iron powder electrodes, high-efficiency gravity electrodes, etc., or special electrodes such as bottom-layer electrodes and vertical downward electrodes should be used to improve welding productivity.

2. The use of welding wire: it is mainly used for the repair of some heat-resistant parts, and the temperature is generally controlled at about 40 degrees Celsius, and the wall thickness is in millimeters, and the maximum is not higher than 100 degrees Celsius.

3. The use of solder sheets: mainly used for gas flame, high frequency, resistance, furnace brazing methods, brazing copper, copper alloy, steel, cast iron, cemented carbide, etc.

The two and three have different overviews:

1. Overview of welding rod: the metal strip filled in the joint of the welded workpiece is melted during gas welding or electric welding of the welding rod. The material of the electrode is usually the same as that of the workpiece.

2. Overview of welding wire: welding wire is used as a filler metal or as a wire welding material for conduction.

3. Overview of solder sheets: There are phosphorus copper, oxygen-free copper, copper solder (welding wire, welding rod, welding ring) and silver-free welding wire with special strength requirements.

Third, the materials of the three are different:

1. The material of the electrode: The electrode is a melting electrode coated with coating for arc welding of the electrode, which is composed of two parts: the coating and the welding core.

2. The material of the welding wire: in gas welding and tungsten gas arc welding, the welding wire is used as a filler metal; In submerged arc welding, electroslag welding and other MIG/MAG arc welding, the wire is both a filler metal and a conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux.

3. The material of the solder sheet: it belongs to copper-zinc alloy brazing metal.

The difference between electrodes, wires, and solder tabs is that the shape is different.

Welding rod is a welding material with welding core and coating, which is generally welded with an electric welding machine.

Welding wire is divided into two types: solid and flux-cored wire, which are usually welded by argon arc welding machine or gas shielded welding machine.

Solder sheets are generally extruded and generally used for brazing welding, such as tin solder sheets, silver solder sheets, nickel solder sheets, copper solder sheets, and are mainly used for brazing welding.

The welding rod is used for manual arc welding, with coating, coating protection; Welding wire is used for argon arc welding, secondary protection welding, submerged arc welding, etc., gas protection or other forms of protection; The solder sheet is made of silver, copper, zinc, cadmium, and other metals, and is rolled into a thin sheet of about 20 wires, which is used for the welding of various small metals such as band saw blades and marble saw blades, and has the characteristics of high welding rules and strength.
