Welding of stainless steel tanks

In the process of making stainless steel tanks, welding plays a pivotal role. If you fail to master the welding technology and methods, it is likely to cause problems such as thermal cracking. So, about the welding method, the required technical requirements and precautions, what are the specific aspects covered?

In the stainless steel tank welding operations, although there are a variety of welding processes, but the most widely used is undoubtedly argon arc welding, especially manual argon arc welding. Such welding, need to follow the principle of small current, fast welding, short arc narrow channel welding, and ensure that the interlayer temperature is maintained below 95 degrees Celsius. In addition, the choice of welding material is also critical to ensure that it matches the base material, otherwise it will affect the overall effect of welding.

In order to effectively prevent thermal cracks that may occur during the welding process, we should use low hydrocarbon electrodes, and ensure that the arc crater is completely filled during welding, and at the same time use the slow arc closing method to form a crescent-shaped arc closing pattern. In the process of extinguishing the arc, need to accurately control the time interval, to ensure that before the start of the next weld, the arc of the last weld has been transformed into a dark red.

In the welding process of stainless steel tanks, strict adherence to the above technical requirements and process specifications, will greatly help us to manufacture high-quality stainless steel tanks.
