Shielding Gas
Shielding gas protects the welding area from atmospheric elements that could compromise the integrity of the weld.
- Types of Gas: Argon is commonly used, and a cylinder may cost you around $30 to $60.
- Usage Rate: You may need one cylinder for every 20 hours of work, depending on the flow rate and project details.
Filler Metals
Filler metals add material to the weld and can vary in cost depending on the material.
- Types of Filler Metals: The most common types are stainless steel, aluminum, and titanium. These can range from $5 to $20 per pound.
- Amount Required: The amount you’ll need depends on the project. For a medium-sized project, expect to use around 10-20 pounds.
Labor Costs
Labor costs often make up a significant portion of overall TIG welding expenses. This includes skilled labor rates, time estimates for projects, and any additional training that might be required for specialized jobs. Here’s how to break down these elements.
Skilled Labor Rates
The cost of labor varies by location, expertise, and the complexity of the job.
