What should I pay attention to when welding stainless steel metal hoses?
When welding stainless steel metal hose, there are many things to pay attention to. First of all, we need to understand the characteristics of stainless steel metal hose, it has the advantages of high temperature resistance, corrosion resistance, wear resistance, etc., and can also be used for high pressure occasions. Therefore, in the welding process, we must be very careful to ensure that the quality of welded stainless steel metal hose to meet the standard. Let us take a look at what matters should be noted when welding stainless steel metal hose.
One. To pay attention to is the preparation work before welding. We should first check the surface of the stainless steel metal hose whether there is oil, rust and other impurities, if there is, it needs to be cleaned first. At the same time, it is also necessary to check whether there are foreign objects inside the stainless steel metal hose, if there are, they also need to be cleared to avoid affecting the quality of welding. In addition, before welding, the welding area needs to be polished, so that the surface is smooth and uniform, so as to ensure the solidity of the weld. II. It is the precautions in the welding process. When welding, you need to choose the right welding equipment and welding method. Usually, the welding of stainless steel metal hose using TIG welding or MIG welding. Before welding, a test weld is required to determine the welding parameters, and then formal welding. During the welding process, attention should be paid to the stability of welding current and voltage to avoid causing poor welding or welding fracture. In addition, the welding area needs to be cleaned and polished after welding to make the surface smooth and uniform.
 
III. Is the inspection and maintenance after welding. After the welding is completed, the welded area needs to be inspected to ensure that the quality of the weld meets the standard. If any problem is found, it needs to be repaired in time. At the same time, in the usual use process, need to pay attention to the maintenance of stainless steel metal hose, timely cleaning and oiling, in order to extend its service life. In short, welding stainless steel metal hose needs to be very careful, because its quality is directly related to the safety of people's lives. Only in strict accordance with the standard operation, to ensure that the welding out of the stainless steel metal hose quality is reliable.
