Where Welding Goes Wrong

Webinars 19 May 2022

Avingtrans Exclusive Webinar: Where Welding Goes Wrong - Flaws, Reasons and Consequences 

Welding is a critical fabrication process and, if not correctly applied and controlled, can lead to unacceptable flaws in the finished and operating structure that can render it unfit for purpose as design intended. These situations can be very costly to rectify and may also lead to expensive legal proceedings in order to determine liability. Unfortunately, the liability in these cases isn’t always straightforward. Whilst the product might have failed or be rejected around or in the weld area, there are many potential causes of this. The failure of the owner or purchaser to correctly specify the level of quality of welding required for service, the designer in neglecting to take account of critical environmental factors such as fatigue loading or corrosion, the supply of poor quality base material and/or the welding fabricator not carrying out the proper controls of welding or inspections to produce a fabrication that is fit for purpose, can all be potential causes.

This talk will cover some experience of the types of disputes related to welding that have occurred in recent years and that TWI has been involved with. Specifically in terms of how the failures in the welding process or otherwise were caused, how the liability was established and what were the consequences.
