GMAW-P (Pulse arc welding)

Four years of NNS or naval shipyard experience as a first class Welder. Required Skills:

• Multi-pass. All position fillet and butt welds using the following processes: SMAW (Shielded Metal Arc Welding), GMAW (Gas Metal Arc Welding), FCAW (Flux Cored Arc Welding) and GMAW-P (Pulse Arc Welding).
• Heating - Oxygen/Propane Heating Torch.
• Experience working in a physically demanding environment (shipboard, sub-assemblies, ladders, staging, etc.).
• Familiarity with OSHA regulations relative to the shipbuilding industry.
• Air Carbon Arc Gouging.
• Ability to properly use fillet and butt weld gauges.

All Welders will be required to pass all position, Multi-pass Butt Weld, Welder Qualification Tests prior to reporting for the first day of productive work. These tests will be in accordance with MIL-STD-248D Paragraph 5.3.3 and the following:

• All position (Horizontal (2G), Vertical (3G), and Overhead (4G)) SMAW (Shielded Metal Arc Welding) process.
• All position (Horizontal (2G), Vertical (3G), and Overhead (4G)) FCAW (Flux Core Arc Welding) process.
• Horizontal (2G) position GMAW (Gas Metal Arc Welding) process.
• All position (Horizontal (2G), Vertical (3G), and Overhead (4G)) GMAW-P (Pulse Arc Welding) process.
• Air Carbon Arc Gouging proficiency test.

The Welding School will administer the following tests:

1. All Welding Qualification Tests in “A” (6 hours), “B” (12 hours), “C” (4 hours) above.
2. Visual Inspection of Welds Level I (4 hours).
3. Welders Vision Test (5 minutes).
4. Air Carbon Arc Gouging Proficiency Test (1 hour)
