TIG (Tungsten Inert Gas) welding, also known as Gas Tungsten Arc Welding (GTAW), is a precise and versatile welding process. Here’s a comprehensive overview of the responsibilities and requirements for TIG welders.
Job Responsibility:
Set up and adjust the TIG welding machine, including selecting the appropriate tungsten electrode, filler rod, and shielding gas
Clean and prepare the metals to be welded, ensuring they are free of contaminants like rust, paint, or grease
Perform TIG welding on various metals (aluminum, stainless steel) using the correct technique for each material
Ensure high-quality welds with consistent bead appearance, proper penetration, and minimal defects
Adjust welding parameters such as current, voltage, and gas flow according to the specific job requirements
Inspect welds for defects such as cracks, porosity, and incomplete fusion
Perform or assist in non-destructive testing (NDT) like X-ray or ultrasonic tests if required
Record welding parameters, inspection results, and any issues encountered
Follow all safety protocols, including wearing protective gear like welding helmets, gloves, and aprons, and ensuring proper ventilation
Regularly clean and maintain welding equipment to ensure optimal performance and safety
Safely handle and store welding materials and gases
Work closely with other welders, engineers, and project managers to meet project specifications and deadlines
Address and resolve any issues that arise during the welding process
Requirements:
Proficiency in TIG welding techniques, including the ability to weld thin materials and achieve high-quality welds
Understanding of different metals and their welding properties
Certification from recognized bodies can be required or preferred
Completion of formal welding training or apprenticeship programs
Strong hand-eye coordination and the ability to perform precise movements
A keen eye for detail to ensure welds meet specifications and standards
Physical stamina to handle long hours of welding and working in various positions
Knowledge of safety procedures and the ability to recognize and mitigate hazards associated with welding
Ability to read blueprints and technical drawings and make precise measurements
Skills in calibrating and adjusting welding equipment to achieve desired results
Ability to diagnose and fix problems related to welding defects or equipment malfunctions
