A Tig Welder is a machine that is used to weld two pieces of metal together. The machine uses an electric arc to heat the metal, which melts the metal and allows it to be joined together.

Tig Welder job duties include:

  • Read and interpret welding blueprints, drawings, and specifications
  • Determine the appropriate welding equipment or method based on requirements
  • Set up components for welding according to specifications (e.g. clamping, bracing, fixtures)
  • Operate angle grinders to prepare the parts that will be welded
  • Align and fit components using calipers, rulers, etc.
  • Weld components using manual or semi-automatic welding equipment in various positions (vertical, horizontal, or overhead)
  • Inspect completed welds to check for defects
  • Remove rough spots from workpieces with power grinders or hand tools
  • Repair broken or cracked parts and fill holes with weld material

Tig Welder Job Requirements

Most Tig welders have a high school diploma, although some jobs may require postsecondary education, and most welders must complete a welding program. Many Tig welders are certified through the American Welding Society (AWS). Some jobs may require certification in a specific welding process, such as 6010 root pass welding. Many Tig welders have several years of experience.

How to become a Tig Welder

Tig welding is a type of welding that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas, which is typically argon. Tig welding is most commonly used for welding thin sections of stainless steel and aluminum, but can be used on almost any metal.

To become a Tig welder, one must first have a basic understanding of welding safety and metallurgy. They must also be able to set up and operate Tig welding equipment. Some welders learn through on-the-job training, while others may attend formal welding school. Many welders are certified through the American Welding Society (AWS).

The AWS offers several levels of certification for Tig welders. The most basic level is the Certified Welder (CW) credential, which requires passing a written test and demonstration of welding skills. More advanced levels of certification include the Senior Certified Welder (SCW) and the Master Certified Welder (MCW). These credentials require more extensive knowledge and experience in welding, as well as passing additional tests.

To become a successful Tig welder, one must have good manual dexterity, hand-eye coordination, and problem-solving skills. They must also be able to work in tight spaces and be comfortable working with high temperatures.
