Segments in this Video

Inert Gases, Shields, and Safety (03:00)


Inert gases, helium and argon, require good ventilation. Shields clean high quality welds from contamination. Safety and preparation procedures are covered in a systematic fashion.

Setting Up and Shutting Down (04:19)

Treatment of the inert gas cylinders and regulator attachments is explained. Proper electrode use and flow meter reading is imperative. Methodical electrode assembly and machine setting is covered.

TIG's Porosity and Tungsten Inclusion (02:04)

"Laying a bead" properly is illustrated. Porosity results in defective welds from gas contamination. Tungsten inclusion melts the electrode and results in a poor quality weld.

Gas Tungsten Arc Welding is also known as “TIG,” or tungsten inert gas welding,  presents special safety concerns. Viewers are warned of the suffocation hazards present when working with inert gases and why good ventilation is required. The video also provides an explanation of how TIG welding differs from other types of particular the use of non-consumable electrodes. Electrode leads, hoses, regulators, and collets are demonstrated and explained as well as the use of the post flow timer to protect the weld from contamination. Also discussed are using the correct collet set and electrode size and type needed for the job. (11 minutes) A Meridian Production.
