Description

Mode of workshop: Online(Live & Interactive)

The workshop will cover topics related to Fusion Joining process, including Weld metal related issues, Heat affected zone and Weld bead geometry.

It will also discuss Brazing and thermal cutting related issues and issues specific to dissimilar metal joining and techniques for detection of the weld defects.

Day 1: 

Module Name: Fusion Joining process

Concepts Covered: 

Weld metal related issues:

Cracking, porosity, inclusion, solidification, and liquidation, cracking lack of fusion/penetration.

Heat affected zone:

Cold crack, under-bead, crack, embrittlement, type IV cracking, weld decay, knife line cracking.

Weld bead geometry:

Bead angle, undercut, reinforcement, roughness, crater.

Learning outcome:

Identification of weld defects.
The mechanism leading to weld defects methods minimizing weld defect related issues.

 

Day 2: 

Concepts Covered: 

Brazing, and thermal cutting related issues.

Issues specific to dissimilar metal joining and techniques for detection of the weld defects.

Learning outcome:

Identification of weld defects.

The mechanism leading to weld defects methods minimizing weld defect related issues.

Session dates: 9 th & 10th July 2022

Time: Sat (10 – 1pm) & Sun (10 – 12pm)

Last date of Registration: July 04th, 2022
