Joint Design and Preparation
The air carbon arc gouging process has been specified to perform back-
gouging on a complete penetration joint to be welded from both sides.
The equipment required to perform this work includes:
- Correct Answer - A shielded metal arc welding machine, a carbon and
graphite copper clad electrode, and a compressed air line delivering up
to 690 KPa (100 psi).
In North America, when oxy-fuel cutting, the fuel gas supply hoses are
always:
- Correct Answer - Red
The disadvantages of water jet cutting include:
- Correct Answer - High initial cost, frequent nozzle replacement,
disposal of spent water contaminated with abrasives and high noise
level.
, Plasma arc cutting requires selecting appropriate shielding gases for
cutting various types of materials. For the cutting of aluminum plate:
- Correct Answer - nitrogen should be selected.
There are two types of corner joints:
- Correct Answer - Open corner, closed corner.
The five basic types of joints are:
- Correct Answer - Edge, lap, butt, T, and corner.
T-joints are prone to distortion, though this can be minimized by -
Correct Answer - tack welding at both ends and on both sides.
What is a surfacing weld? - Correct Answer - A weld that is applied to a
surface, not making a joint.
Edge welds are neither groove welds nor fillet welds. - Correct Answer -
True
The term "Cladding" refers to - Correct Answer - Creating a corrosion-
resistant or heat-resistant layer.
