TIG welding (GTAW) requires the following types of materials: Gases (inert gases: Ar argon, helium He), non-melting electrodes (welding needles), secondary welds. Gas protection The most common protection gas in TIG welding machine is argon gas. Argon gas must meet the purity requirements of 99.967% of the low vapor fraction below 0.005mg / l. Helium […]

In order to practice Tig welding, it is recommended to use 2 to 3mm thick solders. With a large thickness, the welded material will have a larger weld pool and is easier to control than thin welds, which makes it easier for the worker to learn and develop skills than wrestling. With flammable thin plates. […]

Submerged arc welding technology (SAW), is the molten welding process where the arc is created by electrodes (welded wire) and the solder is protected under the drug layer. Welding to avoid the harmful effects of air. Under the effect of the heat emitted by the arc, the weld bead, the welded wire and a part of […]
