The welding machine used should have: high-frequency arc-inducing performance, welding current with increasing and decreasing performance, and excellent arc-stable performance under small current. Wait.Welding Procedure | Arc Welding Machine Method Place the 45° elbow to the end of the pipe leaving a small welding gap, similar to item 4.3.3 for Pipe to Pipe fit up. Place a 45° spirit level on the face of the elbow until bubble is centered and ensure that there is no high-low situation or misalignment between the two outside surfaces. Tack weld in place both the pipe and the elbow
the heat needed for the welding operation. The arc and the weld are protected from atmospheric contamination by a gas shield. The shielding gas can be: pure argon argon mixed with small amounts of other gases helium or carbon dioxide according to the metal being welded.

Generally, after arc welding, the argon gas is used for cooling, so that the generated arc space becomes small, that is, the arc diameter becomes small, and the temperature in the arc changes high. However, the arc is not directly contacted by the metal, but is turned on by a high current after being broken down by a high voltage. Stainless steel welding

The first three How to Set Up Argon for TIG Welding Welding MastermindTungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a tungsten electrode which is non-consumable to produce the weld. The weld area and electrode are protected from oxidation and other contamination by an inert shielding gas such as argon or
Gas Tungsten Arc Welding (GTAW / -TIG-)
Welding-grade argon shielding gas with a 99.996% minimum purity is suggested for most welding situations. Helium, or mixtures of argon/helium or argon/hydrogen may be advantageous in certain situations, such as high travel speed, highly mechanized welding operations, in order to Gas Shielding, Weld Purging, and Backup Techniques dia pipes Argon arc weldingThe continued flow of purge gas during welding, as in 9.1, escapes through the pipe and thus prevents air from entering. e. Cut a 25.4 mm (1 in) long slit in the top of the plastic bag, permit gas to flow long enough to purge all traces of atmosphere from the argon filled bag, then insert and tape in place the head of a small GTAW torch to reach the weldment.Gas Metal Arc Welding - Lincoln ElectricGas Metal Arc Welding (GMAW), by definition, is an arc welding process which produces the coalescence of metals by heating them with an arc between a con- tinuously fed filler metal electrode and the work. The process uses shielding from an externally supplied gas to protect the molten weld pool.
