Welcome to the Structural Steel Welding Seminar
Structural steel welding plays a vital role in infrastructure growth and building
construction. The welding of structural steels is often regarded as being simple, but
in reality requires an in depth understanding of the structural steel codes and
standards as well as the implications of welding these steels. The welding of
structural steels particularly in the construction of large buildings and bridges,
offers a unique combination of the welding engineering and civil engineering
fields. The aim of the structural steel welding seminar is to bring a high level of
understanding to the subject by approaching it from several different aspects: real
world experience welding structural steels, consumables and welding processes
relevant to structural welding, structural welding codes and standards, and stress
analysis relevant to structural steel welding.
The seminar will conclude with an open floor panel discussion that allows you to
raise questions or address comments that arose during the seminar. We strongly
encourage anyone working with structural steels to attend this once in a lifetime
opportunity.

Design of welded steel structures – from the laboratory to the field
Abstract:
The introduction of first limit states design standard for the design of civil engineering steel
structures in the mid 1970’s was a significant milestone in the development of design standards
of civil engineering work in Canada. Over the past 50 years, much research has been conducted
all around the world to develop design procedures to make civil engineering structures safe and
the design process more efficient. This presentation will give an overview of the structural
design process for welded connections using Limit States Design philosophy adopted in
Canadian design standards CSA-S16 and CSA-S6. Some of the design considerations for welded
connections, including the effect of load eccentricity, residual stresses, strength, ductility and
toughness of welds will be examined and we will see how these have been incorporated in design
standards. We will also discuss the underlying assumptions with regard to welding quality and
the importance of the quality control process to achieve the level of safety that the design
standards are trying to achieve.

Gilbert Grondin, PhD, P.Eng., holds the position of
Senior Bridge Engineer/Technical Lead with AECOM
Canada Ltd. where he provides technical support in
various structural steel issues to multiple AECOM
offices and is part of a large team of bridge and
transportation engineers. Prior to joining AECOM in
June 2012, he spent 20 years in academia at the
University of Alberta, where he was professor in the
Department of Civil & Environmental Engineering for
17 years, University of Moncton and Memorial
University of Newfoundland. He also worked for
Buckland & Taylor Ltd in Vancouver, and was
visiting researcher with the Institute for Research in
Construction of the National Research Council. His
research work focused on the behaviour and design of
steel structures with focus on welded and bolted
connections, fatigue, corrosion and structural stability.
Gilbert currently serves on multiple CSA standard committees, including CSA-S6 – Design of
Highway Bridges, of which he chairs the steel structures sub-committee, CSA-S16 – Design of
Steel Structures, CSA-G40.20/G40.21 – Structural Quality Steel. He is co-author of Limit States
Design in Structural Steel and “Calculs aux états limites des charpentes d’acier”, published by
the Canadian Institute of Steel Construction.
Navigating Canadian Standards for Structural Steel Welding
Abstract:
Through the Canadian Standards Association, Canada has a full suite of welding standards for
use in the fabrication and construction industry. This presentation will cover the key standards
that impact structural welding in Canada, the scope of application of the various standards, and
the role of different stakeholder groups in the use and application of these standards. In addition,
the key concepts and principles of these standards will be reviewed including common questions
and misconceptions related to their interpretation and use.

Effects of Electrode Design and Process Selection for FCAW-G
Abstract:
The development of electrodes that are specifically designed to be used with either Ar/CO2
blends or 100% CO2 shielding gas provides end users with a wider range of shielding gases than
a single high-strength electrode can provide. With the current rise in the price of argon, the
switch to higher blends of CO2 in shielding gas is becoming increasingly economical. The
metallurgical considerations when selecting a wire and shielding gas combination are discussed,
including the resulting alloy recovery, strength, toughness, and hardness for a family of FCAW-
G electrodes. Additionally, the effect of shielding gas on the arc characteristics and transfer
mode will be shown through high-speed video footage and useful processing techniques.

Weld faults: how they happen, how to prevent them, and how to
repair them
Abstract:
Weld faults in structural steel construction can result in structural failures, particularly where
critical components are concerned. Structural weld discontinuities, dimensional faults, and weld
anomalies and the typical causes of these faults will be discussed. The general classes of weld
faults will be discussed as well as strategies of how to avoid them and effectively repair them if
they occur. This session will include several real life examples of weld faults.
