Welder Trade
A gas welder fuses metal parts together using a welding rod and an oxygen-acetylene flame to create strong joints.
Key Responsibilities:
Key Responsibilities:
- Preparation & Inspection:
- Examine metal parts to be welded.
- Clean the surfaces for proper bonding.
- Hold parts together using suitable devices.
- Create a narrow groove (if required) to guide molten metal for a stronger joint.
- Equipment Selection & Testing:
- Choose the correct welding rod, nozzle, and torch based on the material and joint type.
- Test the welding torch for proper functioning.
- Safety Measures:
- Wear dark glasses and protective gear to prevent eye and skin damage.
- Ensure a safe working environment before igniting the torch.
- Welding Process:
- Release and regulate oxygen and acetylene valves to control gas flow.
- Ignite the torch and gradually adjust the flame.
- Guide the flame along the joint, heating it to the melting point.
- Melt the welding rod and evenly spread molten metal along the joint.
- Finishing & Quality Check:
- Inspect the welded joint for shape, size, and strength.
- Identify and rectify any welding defects.
