Stainless steel is widely used in various sectors of the national economy, because it is resistant to corrosion in aggressive areas and in atmospheric precipitation. In addition, it can be easily processed in various types. Particular attention should be paid to the welding of steel, on the correctness of which the durability of the seams depends, and, therefore, the stability of the entire structure.
Stainless steel is best welded by argon arc welding. The most popular welding methods are inert gas tungsten arc welding, plasma and laser welding. The use of each of the above methods is due to the conditions in which welding is carried out and the requirements for the steel to be welded.
To weld two separate pieces of stainless steel, first figure out how to weld steel. To do this, read a lot of specialized literature on this topic. Then proceed to the practical part of the question. Buy a welding machine and a gas torch to heat the steel.
Also prepare a piece of wire that will act as an electrode when welding. Please note that the chemical composition of the wire should be the same as that of the pieces of steel to be welded. The use of this kind of stainless wire will avoid intercrystalline corrosion. The result is a thin, barely visible, high quality weld bead.
You need to take care of a reliable power source, which you will need when turning on and operating the welding machine. Carry out the cooking process in an industrial environment, where there are autonomous powerful power supplies with a voltage of 380 volts and above. This allows you to weld any size and length of stainless steel.
Before starting work, check the welded steels for defects and flaws. If present, delete them. This will allow you to weld the steel better. If you are a novice welder, seek advice from more experienced colleagues who will share with you the subtleties and nuances of this procedure. Start by choosing well-weldable steels that you can practice on and hone your craft on. Well-weldable steels include those types of steel in which the weld seam and base materials have the same strength without the use of any special technological methods.
