2024 Structural Systems Activity

UPDATED September 6, 2024

The purpose of the structural systems skill activity is to examine students’ abilities to preform skills related to storage, concrete, masonry, plumbing, electrical, fabrication, construction, building materials, ventilation, heating, and air conditioning. In recent years, we have primarily focused on the area of fabrication.
Students should be familiar with measuring tools, know common welding symbols, and be able to interpret shop drawings.

Contestants will be asked to produce weldments using the SMAW and the FCAW-S processes during the 2024 event. No other welding processes will be used during the 2024 event.
Read and interpret a working drawing
Accurately use a measuring tool
Utilize one of several processes to weld, braze, or cut metal
Fabricate, modify, or repair a metal part.
Identify, interpret, and work from industry-standard welding symbols
Complete weldments accurately according to standard welding procedure specifications (WPS)

Lincoln Electric MP 215i machine will be used to complete weldments with one or more processes (SMAW, FCAW)

The the Lincoln Electric MP 215i machine is capable of all three processes (SMAW, FCAW).
Oxy-Fuel Processes will not be included in the 2024 skill.

Specialized Safety Equipment

Necessary equipment such as basic welding helmets or goggles with a minimum of a shade 10 lens, fire-resistant welding jackets/shirt, gauntlet style welding gloves, welding leathers, and hearing protection devices, in good condition (i.e., no frays on pants) must be brought by each team. Hooded shirts do not qualify as a welding jacket. Participants without proper PPE and welding attire will not be allowed to weld.

CS.03.04.03.b. Assess and demonstrate appropriate operation, storage and maintenance techniques for AFNR tools and equipment.
PST.01.03.01.b.Analyze the situation and determine the best welding and cutting process to be used in metal fabrication.
PST.01.03.01.c.Evaluate the quality of metal fabrication procedures (e.g., SMAW, GTAW, fuel-oxygen and plasma arc torch, etc.).
PST.01.03.02.b. Assess and select the proper electrode for use in various shielded metal arc welding situations
PST.01.03.02.c. Construct and/or repair metal structures and equipment using metal-fabrication procedures.
PST.04.02. Performance Indicator: Determine structural requirements, specifications and estimate costs for AFNR structures
PST.04.03. Follow architectural and mechanical plans to construct, maintain and/or repair AFNR structures (e.g., material selection, site preparation and/or layout, plumbing, concrete/masonry, etc.).
PST.04.03.01.c.Select materials for a project based upon an analysis of the project and the quality of the materials.
