Half-day Workshop on Tungsten Inert Gas (TIG) Welding

Date, time & venue
2017-04-28;1:45 pm (registration) for 2:15 pm to 5:45 pm;Room Y302, The Hong Kong Polytechnic University, Hunghom, Kowloon


Scope and Objectives
At present, welding is widely used in construction industry of Hong Kong and worldwide. The Code of Practice for The Structural Use of Steel 2011 specifies the requirements of welding in terms of Welding Procedure Specification, welders’ certificates and the acceptance of workmanship.


Tungsten inert gas (TIG) welding, also known as Gas tungsten arc welding (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.


TIG is most commonly used to weld high quality root welds for carbon and alloy steel pipings. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, TIG is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.


This workshop aims to give an overview of TIG welding process and covers its welding procedure specifications, welder qualification tests and common associated defects for professional engineers, particularly Technically Competent Person (TCP) of the Supervision Plan System under the Buildings Ordinance.


Mr. Vinodh Kumar is the Manager (NDT & Welding) of Fugro Technical Services Ltd., Hong Kong. Mr.Vinodh acquired his B.Eng (Hons) fromAustralia and has gained many international Certifications in NDT, Welding, Painting,Coating,Asset Integrity and QHSE Management Systems.
