Stainless Steel Pipe Tube Welding method
Stainless steel pipe welding method
There is no shortage of life in many steel materials appear, one of the stainless steel is widely used by people. Stainless steel due to air and water and other weak corrosive media has a very good durability, and stainless steel pipe in addition to direct use, but also for some uses to carry out welding, today we come to talk about what is the welding method of stainless steel?
Stainless steel, also known as stainless acid-resistant steel, as early as 1914 years during the war, because the soldiers of the damaged firearms weapons, making people began to break the corrosion of some of the material began to study, and then the emergence of stainless steel can not solve the guns Problem, but the study of stainless steel is other areas can be used very good material, it for acid, alkali, salt and other media have a very good corrosion resistance. Stainless steel welding
In the presence of stainless steel, some of the stainless steel welding process also developed. Stainless steel is more common welding methods are manual welding, as well as metal metal gas protection welding tungsten inert gas shielded welding of these three methods.
We have to do the welding work before the stainless steel welding, the general situation of 4 mm or less than 4 mm thickness of stainless steel can be directly welded, do not open before welding, it can be a single Welding head operation method. And 4 mm to 6 mm thickness of the stainless steel interface can be double-sided welding, but also do not open the mouth. And in the 6 mm above the V, X, U shape of the opening. Then after the stainless steel wire to fill, in order to improve the quality of welding after the degassing, degreasing and descaling work can not fall. In the case of
In the welding of stainless steel, the relevant parameters of welding is to consider the amount of clear. Because the key to weld formation is mainly about welding current, the relationship between arc and arc, such as the voltage of the arc at 8V, the arc length of the arc is 0.5 mm, and the arc voltage in the case of 10V The arc length of the arc is 3 mm. And the size of the welding current is to determine the size of the size of the welding electrode, the greater the diameter after the supernumer, indicating that the use of welding current is also greater. The welding speed should also consider the welding material, welding position and welding voltage and other aspects of the current. In the case of
Common welding manual welding is a super universal stainless steel welding method, this method in addition to easy to get started, but also can be all the materials for welding, with good practicality. Manual welding operation in the stainless steel welding is more convenient, such as welding the operator's hand is equivalent to the length of the arc, the length of the weld and arc can be adjusted by hand operation.
