TRAINING.

Overview

After participating in this course, you will be able to:

• Analyze joints using fundamental knowledge of various material strengths
• Design welded joints using basic weld design principles
• Prevent failures by using knowledge of metal fatigue
• Apply the fundamentals of welded joints in structures

Description
Welding provides architects and engineers with an economical technique for complete freedom in structural design and development. The widespread recognition of welding as a safe means of making structural connections has come about only after years of diligent efforts and heavy documentation of research findings and successes.

This course will discuss the different welding techniques used in the structural engineering fields, residual stresses, and how to minimize weld distortion. It will also focus on achieving safe designs for welded structural connections, providing participants with the necessary skills to ensure the long-term safety of their structures. Issues of static load and fatigue will be discussed, along with possible design improvements.

Who Should Attend
Fabricators and engineers who are involved in the design and assessment of welded structures • Engineers who are involved in the Fatigue Analysis of Structures Subjected to Repeated Loading • Structural Consulting Engineers • Project Managers • Construction Engineers.
