What are the factors that affect the shape and performance of the submerged arc welding seam?

The first to bear the brunt are the welding parameters. Welding parameters are one of the important factors affecting the shape and performance of submerged arc welding seam. Welding parameters include welding current, voltage, welding speed, etc. If the welding parameters are incorrect, it will cause poor weld shape, and even weld cracks and other problems.
Like our submerged arc welding process, the size of the welding current and voltage will directly affect the heat of welding, 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 shape of the weld seam will be irregular, and defects such as pores and inclusions may occur inside the weld seam. If the welding current and voltage are too small, the heat of the weld is insufficient, and the strength and toughness of the weld will be affected. If the welding speed is too fast, it will lead to insufficient welding heat, 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.
Secondly, the material quality and welding equipment will also affect the shape and performance of the submerged arc welding seam. The most advanced welding equipment is used to achieve high-efficiency production, and the welding process, welding speed and temperature are automatically controlled to ensure the welding joint the quality of.
