How to select welding materials

When selecting welding materials, the following aspects need to be considered: the performance of the welding joint, the welding process performance and manufacturing process performance of the welding joint, and the economy of the welding material.

When selecting welding materials, the performance of the welding joint must be met first. This means that various performance requirements must be considered, such as strength at high temperature, impact toughness, chemical composition, hardness, strength at room temperature, etc. In addition, technical standards and some other special requirements should also be considered, such as high-temperature oxidation resistance, corrosion resistance, and lasting strength. When selecting, these performance requirements must be fully considered.

Secondly, the requirements of the welding process performance and manufacturing process performance of the welding joint must be met. During the welding process, various materials and structures require certain cutting processing and various forming work, including stamping, turning, planing, rolling, bending, etc. Therefore, welding materials need to have good cutting performance, high-temperature comprehensiveness and other performance requirements. The selection of welding materials and the quality of their process performance directly affect the quality of welding.

Finally, the selection of welding materials should be reasonable and economical. While meeting the production process and other performance requirements, attention should also be paid to selecting cheap materials to reduce production costs and increase profits. When purchasing, you should make comparisons and references in many aspects to select welding materials with suitable performance and low price to reduce manufacturing costs.
