Notch toughness at low temperatures of the weld It is a guideline for choosing welding wires. Flux filament wire Different at the end of the code, there are 12 types, namely T-1 , T-2 , T-3 , T-4 , T-5 , T-6, T-7 , T8 , T-10 , T-11 , T-G and T-GS
Note: Welding is a job with a high income potential for people working in this job. Especially with people with high welding skills. You can learn about electric and gas welding. And find more welding equipment at our website : https://www.udo.co.th/product/detail/yawata-316l-16
T-1 type welding wire
This group of welding electrodes requires CO as the cover gas, however the argon-CO gas mixture It can be used as well. to improve welding properties especially to be able to weld in difficult welding positions. The reduction of CO content in the argon-CO gas mixture will increase the amount of manganese and silicon in the weld which improves impact properties and to be able to weld both single welding and welding rod Welding wire larger than 5/64 inches (20 mm.) is used for welding flat and level filets. Welding rods smaller than 1/16 in. (1.6 mm) are used for all welding positions. This type of welding electrodes provide sprayed metal water transfer , low spatter , slight weld bulge , moderate slack content and thorough weld coverage .
T-2 type welding wire
This group of wires is a wire with the same properties as T-1 welding wire, with a high content of manganese or silicon or both, and is designed for single-line welding in flat position and horizontal filet. This type of wire has a high content of oxygen reducing elements. This makes it possible to single-line welding on scaled steel or rimmed steel. The alloying element of T-2 welding wire is not specified. The oxygen reducing element used is manganese. which improves mechanical properties However, T-2 welding rods can be used for welding scaled materials from thick rolling, rust or other materials on the work surface. Better than welding with T-1 welding wire, the weld body has passed the radiation inspection. The arc properties and wire filling rate are similar to that of T-1 welding wire.
T-3 type welding wire
This group of welding wires is a wire that uses a built-in gas shield. (Self-shielded) Use with direct current, positive wire connection. and transmission of metal as a spray Slag is designed to be able to weld at high speeds. It is used for single-line, flat, level and down welding work at an angle of up to 20 degrees on steel plates not thicker than 3/16 in. (4.8 mm.) and should not be used to weld materials that are too thick. Over 3/16 in. (4.8 mm) or overlapping
T-4 type welding wire
This type of welding is a gas-covered welding wire. use with direct current Anode connection wire and metal water transfer is globular. Slag is designed to be able to weld high melting and serves to reduce the amount of sulfur This allows the weld to be resistant to cracking. This type of welding wire has a low penetration depth. Can be used for both welded and single-line welding applications. Or connect horizontal spoons in a flat and level position.
T-5 type welding wire
This group of wires is designed for cover with CO gas or argon-CO gas mixture, which may be similar to the gas used for type T-1 welding wires. It is used for single- and double-weld welding in flat and folded positions. This welding rod property provides a globular metal water transfer, slightly convex weld shape. Thin slag which may not completely cover the weld This group of welding wires is exchanged as a type. Lime-Fluoride The resulting weld has good impact and crack resistance properties compared to the rutile type.
T-6 type welding wire
This group of welding wires uses a shielded gas. For use with direct current to the anode wire. Spray metal water transfer Slag has low temperature toughness properties, good penetration and slag can be easily removed from deep grooves. Applied to single weld and stack welding in flat and level positions.
T-7 type welding wire
This group of welding wires uses a built-in shielding gas. For use with direct current to the negative wire. has designed a slag to be used for welding with a large welding wire at a high melting rate and small welding wires can be welded in every welding position Slag is also designed to remove sulfur in the weld. to increase the resistance to cracking of the weld This type of welding wire is used for single-line welding and stacking welding.
T-8 type welding wire
This group of welding wires uses a built-in shielding gas. Use direct current to the negative wire. Slag has designed the welding wire to be able to weld in every welding position. Slag also allows the weld to have good impact strength properties. at low temperatures as well and reduce the amount of sulfur in the weld to increase the crack resistance This type of welding wire is used for single-line welding and stacking welding.
T-10 type welding wire
This group of welding wires uses a built-in shielding gas. Use direct current to the negative wire. Slag is designed to allow welding wires to be welded with high welding heat. Used for welding every single weld material thickness In a flat position, parallel position, and welding down at an incline of not more than 20 degrees.
T-11 type welding wire
This group of welding wires uses a built-in shielding gas. Use with direct current to the negative wire. and provide a uniform spray arc Slag is designed to be able to perform all welding positions and weld at high welding speeds as well. This wire is used as a universal wire that can be single- and double-stranded. in every welding position.
