TIG welding requires safety precautions, including proper ventilation and safety equipment. Cleaning the metal is crucial for effective welding, and spot welding can secure pieces together before a full pass. Different weld types require different preparation and execution, and the operator’s movement can vary.
TIG, or tungsten inert gas, is a type of welding process in which a gas is used to prevent tungsten weld contamination. These gases can be harmful, as can the bright light caused by the welding process, so some of the most important TIG welding tips focus on welder safety. All welding should be done in a well ventilated area and the operator should wear all appropriate safety equipment including a safety mask, gloves and flame retardant clothing. If the operator is new to the process, they should only proceed under the guidance of an experienced welder who can provide TIG welding tips during the process.
The most important preparation stage in the process is the cleaning stage. Most TIG welding tips will be ineffective if the metal being welded is not properly cleaned of rust, grease, dirt and other contaminants. Using a wire brush to accomplish this job may be sufficient, but for more stubborn rust and dirt, a wire wheel mounted on a drill may be required. Heavier jobs require an angle grinder, which is a power tool that rotates a grinding wheel at high speed. This tool will remove material from the workpiece and produce sparks, so the user should wear protective equipment when using an angle grinder.
Other TIG welding tips focus more on the actual process. Many professionals recommend spot welding before making a full pass along the metals bonded to each other. This means that the operator will make small, short connections to secure the two pieces together before making a full pass. The pieces will already be locked together for safety, but they may still move slightly; Spot welding reduces or eliminates the likelihood of parts moving before full welding can be done.
It is important to know the different types of welds that can be made. Tips for TIG welding can include learning how to butt weld, weld corner joints, tee joints, lap joints, and so on. Each type of situation will require different preparation and execution; it may also be necessary to modify the metal itself to allow the tungsten to penetrate between the two pieces of metal for a stronger bond. The movement that the operator will have to make during the process can also vary, although many experienced welders recommend a slightly arcing back and forth movement.
