Medium Heavy Plate/As the steel in the production process is often used in the welding process , so for high strength low alloy steels such uses ,/Deformed steel bar Factory/ the arc welding process can be adopted in the case of sheet and strip thickness of such widely used for welding is very important and the production of steel welds should have the strength and toughness requirements are equally important. So as to withstand the most adverse conditions appear to live intended use ./Hot Rolled Coils Factory/ Recently the development of a variety of welding processes and the development of adequate low-alloy high strength steel simultaneously, paying particular attention to ensure that these steels can have a proper welding performance. If the welding operation properly, most of the high strength low alloy steels can be welded well . For large steel and high grade carbon and manganese content , require preheating and ( or ) using low hydrogen electrodes . For some low-alloy high strength steel thickness matter how much should be adopted hypoxia electrodes. On the minimum yield point up to about 345MPa high-strength low-alloy steel gas shielded metal arc welding , using carbon electrodes are usually suitable applicator . For a minimum yield point above about 415MPa steel and weld metal required when special properties , such as higher corrosion resistance , then usually requires the use of low-alloy steel electrodes. For submerged arc welding, gas metal arc welding and flux cored arc welding , welding is recommended as a welding filler metal and gas metal arc welding MIG adopted as proposed . For the automotive industry with high-strength low-alloy steel plate, generally limit their carbon content of not more than 0.13% in order to get a good spot performance.
