PMTX1070X Burning & Surface Welding

Lead Faculty: Mr. William Hyder

Course Description

Fundamentals of metallurgy including the physical properties, structure, and grain of common metals and their alloys, types and properties of steel and the fundamentals of the SMAW welding process. Fundamental and basic/intermediate practical skills of steel cutting, i.e., cutting, piercing, and gouging. Students are taught the skills necessary to obtain competency in both oxyacetylene and ultra-thermic cutting techniques using ultra-thermic and tubular steel burning rods commonly used by diving contractors are included.

Learning Outcomes

  • Describe the use, operation, and safety precautions for the following welding and cutting equipment: Oxy-Acetylene cutting torch, Stick or Arc welder, hand grinders, wax melting pot, and chop saw.
  • Identify the proper personal protective equipment required for carrying on Oxy-Acetylene burning and Arc welding using the SMAW welding process.
  • Explain the safety precautions for use of compressed gas cylinders, oxygen cylinders and flasks, acetylene cylinders, and welders.
  • List the proper personal protective equipment required for Oxy-Acetylene burning and Arc welding using the SMAW welding process; and how to properly choose the appropriate shaded lens when cutting and arc welding.
  • Demonstrate the ability to properly cut steel using a oxygen acetylene torch.
  • Demonstrate the ability to weld steel on the surface in horizontal, vertical, and overhead positions; and to complete a minimum of 30 hours of practice.
  • Demonstrate the ability to cut steel underwater using exothermic and steel tubular cutting rods; and to select the proper current for effective cutting.
  • Explain the theory and concepts of underwater welding.
