Heat-affected zone (HAZ) for the welding

This video will explain Heat affected zone for the welding , how heat transfer happens across the cross section of the weld metal and what are the significance of the heat transfer and heat affected zone
this is very popular topic of advance welding technology and also helps to understand the importance of the pre heat and post weld heat treatment.
more information about post weld heat treatment are in this video:

Hello, I have a question between welding with electrical resistance and mig which has bigger bigger HAZ?

[@kartavyasarware3978]

Very informative

I really enjoy your lessons. Can you explain critical welding. D1.8. That would be Awsome if you have time.👍👍👍

[@weldinginspection7239]

Sure, I will make a video for that, D1.8 : correct? seismic welding code I really appreciate your comment . Thank you

Allready sub and hit that notification button. Im getting ready to take my cwi in feb taking the seminar then part b rescheduling to take part a and c later on with in a month. Any information is appreciated

[@enriquelopez9689]

Do you know about some book that could help me to study , because i have s lot of doubt how to measure a piece with a scanner , I successed to measure it with fillet weld method and those measurements were good . I've been learning with videos on KZbin 😅

crack occurs in Heat Affected Zone, can you explain why it happens?

[@weldinginspection7239]

Hello, I have explained that in this video. thank you kzbin.info/www/bejne/d6XYmGCooJh0r6c

[@cintulator2]

Maybe it is about the steel that you are using? Check the manufacturer.

[@devendrashahare9332]

What is the difference between heat affected zone and Penetration???

[@weldinginspection7239]

heat affected zone is the area where conduction heat transfer occurs because of the welding process. heat from filler metal will slowly transfer to the weld base metal. any area with the temperature change would he heat affected zone penetration is the term how deep your filler metal will go towards the root. penetration is more related to the joint design : it is related to fit up of the joint.
