Welder Trade Career Profile

ROLE OVERVIEW:
Welder technicians are trained to fuse metal components using Gas, Arc, MIG, TIG, and Plasma cutting systems. Welders are crucial for structural engineering, automotive bodies, pipelines, and shipbuilding.

SKILLS REQUIRED:
- Arc welding and gas welding techniques
- Specialized MIG/TIG welding operations
- Reading technical engineering layout drawings
- Weld defect testing and quality inspection

TOOLS USED:
- Welding power sources (transformers, rectifiers)
- Electrode holders, MIG/TIG torches, and gas cylinders
- Protective helmets, leather safety aprons, and slag chipping hammers

GROWTH PROSPECTS:
Specialized welding roles command premium pay in international sectors.

INTERVIEW QUESTIONS:
1. Q: What is the difference between MIG and TIG welding?
A: MIG welding uses a continuously fed consumable wire electrode and shielding gas, while TIG welding uses a non-consumable tungsten electrode with a separate filler rod.
2. Q: What causes welding porosity and how do you prevent it?
A: Porosity is caused by trapped gas pockets due to moisture or dirty base metal. Prevent it by cleaning the metal surface and keeping electrodes dry.
