Huayang Steel Pipe, located in Cangzhou, Hebei, one of the important production bases of China's steel pipe industry, specializes in providing customers with high-quality and high-quality submerged arc welded steel pipe products. And performance is an important index to evaluate the welding quality.
So what are the factors that affect the size, shape and performance of LSAW welds?
1. Voltage and current
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.
2. Material quality
Material quality and welding equipment also affect the shape and performance of the submerged arc weld. And Huayang Steel has cooperated with many large steel mills, such as Shougang Group, Puyang Iron and steel Mill, Jingye Group, Shandong Iron and Steel Group, HBIS Group and so on. We will match according to customer requirements and support on-demand customization.
3. Equipment performance
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 pipes, will stick to the principle of "quality first, customer first" to provide you with better services!
