How thick is the diameter of the welding wire 5

To the common ones, the coarse ones to the coarse.

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(Specifications are generally diameter.)

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

Welding wire classification:1) According to the welding method, it can be divided into submerged arc welding.

Welding wire, CO2 welding wire, tungsten argon arc welding.

Welding wire, MIGG welding wire, self-protection welding wire and electroslag welding.

welding wire, etc. 2) According to the shape and structure of the welding wire, it can be divided into solid welding wire, flux-cored welding wire and active welding wire.

3) According to the applicable metal materials, it can be divided into low carbon steel.

Welding wire, low-alloy steel welding wire, cemented carbide.

Surfacing welding wire, aluminum, copper and cast iron welding wire, 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.

The selection of the diameter of the welding rod is generally selected according to the thickness of the weldment, the joint form, the position of the weld, and the level of the weld.

1. For the I-shaped groove corner joint, T-shaped joint, lap weld and butt weld of the bottom weld of the root cleaning and sealing of the bottom weld on the back, the diameter of the welding rod can be selected according to the thickness of the weldment;

2. If the thickness of the weldment is the same but the welding position is different, the welding rod of different diameters should be selected. For example, in horizontal welding and vertical welding, welding rods with a diameter of 5 mm are rarely used;

3. Different joint forms should be selected with different diameters of welding rods. For example, T-joints and lap joints, because the heat dissipation conditions are better than those of butt joints, thicker diameter welded bright limbs can be selected;

4. The first layer of the joint at the mouth of the open slope Huai hall should be selected with a thinner diameter of the welding rod, such as the welding rod with a diameter of millimeters can be selected when the butt joint is underwelded, and the welding rod with a diameter of 4 millimeters can be selected for the remaining layers;

5. When flat welding of mild steel, the diameter of the welding rod has a general correspondence with the thickness of the weldment.
