Where’s the job?

Overview

• Industrial welding specialists work with various techniques such as MIG, TIG and arc welding to fabricate and repair metal structures with high precision.

• Skill level: 5 / 5 (advanced technique, extensive training and precision required).

• Typical duration: Varies from a few hours for small repairs to several days for large industrial projects.

Safety First

• Always wear appropriate PPE including welding helmets, gloves, fire-resistant clothing and eye protection.

• Ensure adequate ventilation to avoid the harmful effects of welding fumes, and use respiratory protection if necessary.

• Keep fire extinguishers and a first aid kit nearby to counter any incidents involving sparks or burns.

• Inspect all equipment, including cables and connections, before beginning any welding operations.

• Follow manufacturer guidelines for machine setup and maintenance to ensure consistent performance.

Tools & Materials

Step-by-Step

1. Prepare the workspace – clear the area, ensure proper ventilation and remove any flammable materials.

2. Inspect all welding equipment – check cables, gas supplies and the integrity of the machine.

3. Fit-up the joint – align and secure the metal parts with clamps to ensure a uniform gap.

4. Set welding parameters – adjust current, voltage, and gas flow according to the metal type and thickness.

5. Execute the weld – maintain a steady motion, monitor the bead formation and adjust technique as required.

6. Clean the weld – remove slag or spatter using an angle grinder and inspect the joint.

7. Final inspection – conduct non-destructive tests if required, and re-weld any defective sections.

Completion Checks

• Welds should exhibit a consistent bead profile with adequate penetration and minimal defects.

• Ensure there are no cracks, porosity, or undercuts in the joint.

• Any non-destructive testing (NDT) should confirm the integrity of the weld.

• The work area should be left clean with all spatter and debris removed.

When to Call a Pro Instead

For projects involving critical load-bearing structures or specialised alloys, employing a certified industrial welder or welding inspector is advised to ensure compliance with safety and quality standards.
