Welding stainless steel requires the use of direct current,
and the current range may vary depending on the welding method and type of stainless steel. For example, for austenitic stainless steel, the recommended current range is 60-90 amperes; The current range of ferritic stainless steel is 70-100 amperes; The current range of martensitic stainless steel is 80-110 amperes; The current range of duplex stainless steel is 90-130 amperes. These current ranges provide a basic guide, but the actual welding current still needs to be adjusted according to specific welding conditions, including factors such as the thickness of the welding material, welding position, and welding process.
In addition, the selection of welding current will also vary for stainless steel plates of different thicknesses. For example, when welding 2mm thick stainless steel plates, the current is usually between 100-120 amperes, but for thicker plates such as 3mm stainless steel plates, the suitable argon arc welding current is between 70-90 amperes. This indicates that in practical operation, it is very important to adjust the welding current according to specific welding requirements and conditions.
Choosing the appropriate welding current is one of the key factors in ensuring the quality of stainless steel welding. By referring to the above guidance range and adjusting according to actual conditions, the best welding effect can be achieved.
The advantages of stainless steel welded pipes mainly include lightweight production equipment
low investment, fast building material speed, simple welding methods, wide product specification range, high dimensional accuracy, small wall thickness deviation, smooth surface, and high yield.
The production process of stainless steel welded pipes sold by Fengmai Company is simple and efficient, which makes its cost more than 20% lower than seamless pipes in mass production. The production equipment for welded pipes is relatively lightweight, requires less investment, and has fast building materials and simple welding methods. It can produce products with high dimensional accuracy, uniform wall thickness, smooth surface, and relatively high yield. This process not only improves production efficiency, but also reduces costs, making welded pipes have significant advantages in terms of economy.
In addition, during the production process of stainless steel welded pipes,
the pipes will be uniformly squeezed and then undergo online bright solution annealing, making the surface very smooth. This smooth surface is not easy to scale and has anti scaling function. This not only benefits heat dissipation, but also reduces the need for frequent cleaning, thereby saving maintenance costs. The deep processing products of welded pipes have obvious advantages in uniform wall thickness, and can also be customized to any length with high accuracy. These characteristics make stainless steel welded pipes widely used in various industries.
Fengmai Company sells stainless steel welded pipe industrial pressure pipelines with full specifications, including national and non-standard stainless steel welded pipe specifications, customized pipe diameters of 6-3500mm, and a stock of over 6000 tons. The production is fast, the delivery time is accurate, and materials can be processed. Fengmai Company has been focusing on the stainless steel pipe industry for 15 years. Your professional consultant for stainless steel seamless pipes is looking forward to cooperation!
