What Is Gas Tungsten Arc Welding? (03:02)

FREE PREVIEW

TIG welding uses the intense heat of the arc to make high quality welds on ferrous metals and non-ferrous metals such as aluminum. Learn the advantages of TIG welding. Skin burns frequently occur while TIG-welding.

Components of a Gas Tungsten Arc Welding System (01:59)

Components include a power source, TIG torch, welding machine, cooling water hoses, foot switch, shielding gas (argon, helium), and ground clamp. High frequency can build up in the work table and surrounding metal fixtures during TIG welding.

Selecting and Preparing the GTAW Electrode (01:50)

Learn common GTAW electrode rod diameters. The AWS classifies tungsten electrodes. Hurrying in a welding environment leads to accidents.

Safe Welding Environment and Protective Equipment (03:12)

Before welding, inspect the work environment for tripping or slipping hazards. Learn how to stay safe in a welding environment. Proper ventilation and personal protective equipment are essential. TIG arc light is more intense than other welding processes.

Setting Up a Gas Tungsten Arc Welding System for Use (02:18)

Always inspect the welding area and all working parts, including hoses and cables. Follow step-by-step instructions and demonstrations for setting up a gas tungsten arc welding system. Safety tip: Never wrap a torch cable around our wrist or arm.

Laying a Bead (05:46)

A welder must know how to manipulate the rod to produce a quality weld. A quality TIG weld means minimal defects, proper tie-in to other beads, and good penetration. A welder controls the current flowing to the puddle with a foot pedal. Advanced technique

Advanced Welding Techniques (02:52)

Advanced welding techniques include knowing how to weld the five basic joint types and their variations. TIG applications include a mild steel lap joint, stainless steel "T" joint, and stainless steel or aluminum corner welds. Always wear recommended ear

Troubleshooting TIG Welding Problems (01:54)

Because many variables occur in the proper set-up of the TIG welding system and its parts, TIG welding is more difficult to master than most other welding techniques. Viewers learn to troubleshoot some of the most common problems in TIG welding.
