Before commencing the welding process, it is necessary to thoroughly clean the stainless steel pipes to eliminate any contaminants like dirt, grease, or oxidation. This can be accomplished using either a degreasing agent or a stainless steel wire brush. Following the cleaning process, the pipes must be aligned and fitted together correctly. It is crucial to ensure that the gap between the pipes remains consistent and even throughout the joint. This can be achieved by temporarily securing the pipes in place using clamps or tack welding. Once the pipes are properly aligned, the TIG welding process can commence. This involves using a TIG torch to create an electric arc between a tungsten electrode and the stainless steel pipes. The intense heat generated by the arc melts the edges of the pipes, creating a fusion between the base metal and the filler material. During the welding process, it is vital to maintain a stable arc length and control the welding speed to achieve a uniform weld bead. Regulating the heat input and controlling the welding parameters can be accomplished by utilizing a foot pedal or a remote control. Throughout the welding process, it is important to safeguard the weld area from contamination. This can be achieved by using shielding gas, such as argon, to establish an inert atmosphere around the weld zone. The shielding gas prevents the weld area from reacting with oxygen and other atmospheric elements that could result in weld defects. Upon completing the welding, it is advisable to perform post-weld cleaning and inspection. This involves removing any slag or spatter that may have formed during the welding process and visually examining the weld for any defects like cracks or discontinuities. In summary, the welding procedure for stainless steel pipes involves cleaning the pipes, aligning and fitting them together, TIG welding with the appropriate arc length and welding speed, shielding the weld area with inert gas, and conducting post-weld cleaning and inspection.
