What are the commonly used welding wire models and specifications, welding wire specifications and m

The method of compiling the electrode model is as follows: the letter "E" indicates the electrode; The first two digits indicate the minimum value of the tensile strength of the deposited metal;

The third digit indicates the welding position of the electrode, "0" and "1" indicate that the electrode is suitable for all-position welding (flat, vertical, vertical and horizontal), "2" indicates that the electrode is suitable for flat welding and flat fillet welding, and "4" indicates that the electrode is suitable for downward vertical welding;

When the third and fourth digits are combined, the type of welding current and the type of coating are indicated.

After the fourth digit, add "R" to indicate moisture-resistant electrode, and add "M" to indicate moisture-resistant and mechanical properties of the electrode, commonly used models.

It is especially suitable for cast iron molds, which can reduce costs due to the reduced nickel content, and make a priming buffer layer on the hard surface of cast steel molds.

Commonly used welding wire models:

Common gas flux cored wires are: LQ122, LQ172, LQ212, LQ337, LQ423, LQ439, LQ451, LQ537, LQ582, LQ585, LQ605, LQ621, LQ666, LQ707, etc.

Welding wire can be divided into solid core wire and flux-cored wire according to its structure.

The diameter of the gas shielded welding wire is relatively small, the minimum is and the maximum is . The diameter of the commonly used welding wire for carbon dioxide gas shielded welding is there, and the diameter of the commonly used welding wire for tungsten gas shielded welding is there.

The flux in the flux-cored wire can play a series of beneficial roles such as the electrode coating to protect the molten droplets, the molten pool from oxidation, nitriding, auxiliary weld forming, stable arc, deoxidation, desulfurization, alloy seepage, etc., and the manufacturing specifications are. Generally, the diameter of the wire less than 2mm is called the thin diameter wire.

Stainless steel flux-cored wire welding points and precautions.

The flat characteristics of the welding power supply are adopted, and the reverse polarity is used in DC welding. You can use a regular CO2 welder to weld, but the pressure of the feed wheel should be slightly loosened.

It should be noted that the shielding gas is generally carbon dioxide gas, the gas flow rate is 20 25l min, and the distance between the welding nozzle and the workpiece is 15 25mm.

The general welding current is about 15mm when it is less than 250A, and about 20 25mm when it is above 250A.

Specifications and models of welding rods:The more commonly used are:

1. CMC-Emagic7 electrode, HRC 52 55.

2. CMC-ECI55 electrode, HRC 55-58.

3. CMC-E46H welding electrode, HRC 44-49.

4. CMC-E64N welding electrode.

5. CMC-ENCD electrode, HRC 25 28 and so on.

The role of electrodes:1. The welding rod is composed of two parts: the welding core and the coating.

The wire should be evenly and inwardly covered with architectural paint (core) on the outside of the metal material core. The type of welding wire is different, the welding core is also different, the welding core is the metal material core of the welding wire, in order to better ensure the quality and characteristics of welding, there are strict requirements for the composition of chemical elements in the welding core, especially for harmful residues (such as sulfur, phosphorus, etc.), its composition should be strictly limited, better than the original material.

2. The metal core coated by the coating in the electrode is called the welding core.

The weld core is usually a very long steel wire, and during operation, the current is conducted, and the generated electrical energy is converted into thermal energy. Or the weld core melts on its own, becoming a metal that has been filled and fused with the metal to complete the weld.
