The University of Ottawa students asked the author (Kevin Bagheri, P.Eng) about the options of Welding Engineering Certification available. Questions about how to get certification and which certification is best seem to reflect a general...

Development of a Welding Shrinkage Estimation Method for High Accuracy Production in Marine Stainless Steel Exhausts<br />CANWELD Conference14, Canada, Vancouver, British Columbia, September 28 – October 01, 2014

Development of a Welding Shrinkage Estimation Method for High Accuracy Production in Marine Stainless Steel Exhausts
CANWELD Conference14, Canada, Vancouver, British Columbia, September 28 – October 01, 2014

Material shrinkage is inherent to the process of welding of structures and components. We have established an accurate method for estimating weld shrinkage in advance so that it may be planned for in the design phase. This enables us to control the accuracy of our welding production system.

Grit Blast Cleaning in Water - Washable Flourescent Liquid Penetrant Examination (LPE) <br />4TH International CANDU and NDT Conference in Canada, Toronto, Ontario, June 2012

Grit Blast Cleaning in Water - Washable Flourescent Liquid Penetrant Examination (LPE)
4TH International CANDU and NDT Conference in Canada, Toronto, Ontario, June 2012

NDT is a required process for the fabrication of aerospace components. The American Society for Testing and Materials (ASTM) Standard E1209 specifies water-washable fluorescent Liquid Penetrant Examination (LPE). The Standard that governs LPE of aerospace components is ASTM E1417.

It is all about GMAW in out of Position Downward and Upward Welding<br />CANWELD Conference15, Canada, St. John's, Newfoundland & Labrador, September 13 – 15, 2015

It is all about GMAW in out of Position Downward and Upward Welding
CANWELD Conference15, Canada, St. John's, Newfoundland & Labrador, September 13 – 15, 2015

Major codes and Weld Procedure Specifications (WPS) require separate welding qualification in vertical up (Upward) and vertical down (Downward) positions for example in power generation, petrochemical, process piping industries, offshore structures, and shipbuilding.

Effect of Post Weld Stress Relieving on Intergranular Corrosion Resistance of Austenitic Stainless Steels <br />CANWELD Conference16, Canada, Edmonton, October 05 – 07, 2016

Effect of Post Weld Stress Relieving on Intergranular Corrosion Resistance of Austenitic Stainless Steels
CANWELD Conference16, Canada, Edmonton, October 05 – 07, 2016

This paper deals with the applicability of various techniques for the assessment and quantification of sensitisation in Austenitic Stainless Steel Tungsten Inert Gas (TIG) welds. Welded joints of AISI Type 321 stainless steel were stress relieved at 760°C for period of up to 10 h.

Quality Requirements for Laser Cutting of Titanium Sheets <br />CANWELD Conference17, Canada, Montreal, September 13 – 14, 2017

Quality Requirements for Laser Cutting of Titanium Sheets
CANWELD Conference17, Canada, Montreal, September 13 – 14, 2017

Different titanium alloys are frequently used in the aerospace industry owing to attractive properties at high temperature service. Manufacturing of those parts is performed by different conventional and non-conventional methods, where laser cutting is one of the latter.
