Do you know the welding process of stainless steel tanks?
Stainless steel tanks, as the name suggests, are stainless steel welded cans. In general, stainless steel storage tanks should have high airtightness and strong corrosion resistance, which puts high demands on the manufacturing technology and welding process of stainless steel storage tanks. So, what is the welding process for stainless steel tanks? Let's take a look at it together.
As we all know, there are many kinds of stainless steel welding processes, and each type of welding quality is also good. However, in the production of stainless steel storage tanks, the most used is argon arc welding, and is generally hand soldered. In argon arc welding, we need to use small current, fast welding speed, short arc narrow channel welding, and the temperature between the control layers should be controlled below 100 degrees. Of course, the welding materials used should also be matched, otherwise it will affect the welding. effect.
In addition, in order to avoid hot cracking during welding, we should also pay attention to the selection of high-quality hydrogen electrode with low carbon content, filling the crater during welding. And it is necessary to collect the arc slowly, forming a crescent-shaped arc. The time interval for arc extinguishing should be well grasped. The next welding should be performed before the last arc point becomes dark red.
In general, as long as we can pay attention to the above matters during welding, we can produce high quality stainless steel storage tanks.
