Inetub Welding Wire classification and selection guidance
Dec 17, 2018

The quality of steel pipe welding wire is mainly determined by the welding wire and the process. Steel pipe welding wire has many detailed classifications, which can be first divided into single layer welding wire, double layer welding wire and multilayer welding wire. From the use category, it can be divided into various repair welding wires and gas shielded welding wires. The high-quality steel wire has smooth wire feeding, stable arc and uniform diameter. The welding wire has small splash, small smoke and high deposition efficiency. Basically, each package of wire is a whole piece of wire with no seams.

 

Steel pipe welding wire is divided into thickness, mainly 1.2mm, 1.6mm, 2.4mm, 2.8mm and 3.2mm. The welding wire of different specifications has different hardness. The hardness of high quality wire should reach above HRC55, the higher the better. The carbon and chromium content determines the hardness of the steel wire, the carbon content of the basic wire is about 3.0-5.0, and the chromium content is between 15-30. After the high-quality steel wire is surfacing, the butt weld layer on the surface should have good impact resistance and not easy to fall off.

 

Steel pipe welding wire can be further detailed according to different industries, and gas shielded welding wire can also be subdivided into impact resistant welding wire, high temperature resistant welding wire, gas shielded repair wire, and welding wire with various special elements to meet different Welding requirements.
