AW-6: Weld a Vertical-up Butt Joint
On completion of this module the learner must be able to use an arc welding machine to weld a vertical-up butt joint between two mild steel plates
Key and critical concepts which you will learn:
A practical test will be set at the end of the module and must be completed without using references.
The learner will be required to use an arc welding machine to weld a vertical-up butt joint between two 8mm or 10mm mild steel plates to the following standards:
- The plates must be prepared according to the method described in the resources.
- Weld penetration must be according to the sample model.
- There must be no slag inclusions.
- Undercutting must not exceed 1/10th of the material thickness.
- The start and finish must comply with the sample model.
- All the safety procedures for arc welding and oxy-acetylene equipment must adhere to.
Tools, consumables, machinery and equipment required:
- Drawing, welding machine, material, chipping hammer, wire brush, welding rods 2.5mm or 3.15mm 6013, welding gloves, welding helmet, oxy-acetylene equipment, portable grinder
It often happens in the work situation that equipment has to be welded on site. If this is the case and the joint runs vertically up, then it must be welded in that way.
