PMC submerged arc welded steel pipe factory, located in Cangzhou, Hebei Province, one of the important production bases of China's steel pipe industry, specializes in providing customers with high-quality submerged arc welded and high frequency straight seam welded steel pipe (ERW) products. Welding technology is crucial to our production of high-quality steel pipes, and the shape and performance of the weld seam are important indicators for evaluating welding quality. So what factors will 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, welding voltage, welding speed, etc. If the welding parameters are incorrect, it will cause poor weld shape, and even weld cracks and other problems.
In the submerged arc welding process, 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, material quality and welding equipment will also affect the shape and performance of the submerged arc welding seam. And our PMC steel pipes have cooperated with many large steel mills, such as Puyang Steel Mill, Jingye Steel Mill, Shanshan Iron and Steel Group, Hegang Group and so on. We will match according to customer requirements and support on-demand customization. Similarly, we 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.
All in all, we, who have rich experience and professional technical ability in the field of submerged arc welding, will stick to the principle of "quality first, customer first" to provide you with better services!
