- The first one is the welding parameters. Welding parameters are one of the important factors affecting the shape and performance of submerged arc welding seams. Welding parameters include welding current, voltage, welding speed, etc. If the welding parameters are incorrect, problems such as poor weld shape and even weld cracks may occur.
For example, in our submerged arc welding process, the size of the welding current and voltage will directly affect the amount of welding heat, thus affecting the shape and performance of the weld. If the welding current and voltage are too large, the welding heat will be too large, the weld shape will be irregular, and defects such as pores and inclusions may occur inside the weld. If the welding current and voltage are too small and the heat of the weld is insufficient, the strength and toughness of the weld will be affected.
If the welding speed is too fast, insufficient welding heat will result, and defects such as pores and inclusions may occur inside the weld, which will affect the quality and performance of the weld. On the contrary, it will lead to excessive welding heat and irregular weld shape, which will affect the quality and performance of the weld.
- Second, material quality and welding equipment also affect the shape and performance of submerged arc welding seams. We have cooperation with many large steel plants, such as Anyang Steel Plant, Anshan Iron and Steel Plant, etc. We will match according to customer requirements and support customization on demand. We also use the most advanced welding equipment to achieve high-efficiency production, and automatically control the welding process, welding speed and temperature to ensure the quality of welded joints.
