Available here in the U.S. , completion earns an Associates Degree ( AA ) and at some institutions an AWS certification. Small companies usually do not employ these individuals whereas large companies look for them as well as "Inhire or basic" weldors. An AA Degree puts you on the fast track to promotion and always pays more.
There are currently two ABET (Accreditation Board of Engineering Technology) accredited universities in the United States for Welding Engineering and Welding Engineering Technology. The universities are Ohio State University and Ferris State University, respectively. Both of which offer a Bachelor's of Science. Ohio State University also offers a Master's and currently a Doctorate in Welding Engineering.

Welding post heating?
This is a simple stress relieving process the welder can do to minimize warpage of material that was just welded.
Is post weld heat treatment is part of Non-destructive testing?
Post weld heat treat is done to bring back strength properties lost during welding. It is not related to non destructive testing
What is the disadvantage of without preheating in welding?
Preheating can assist the welding penetration on materials with high thermal conductivity such as thick aluminum sections or even some steels. This reduces the heat sink affect (rapid cooling) of the deposited weld by the surrounding cold metal. Preheating also significantly reduces the rapid cooldown of the item post welding. Contrary to many beliefs, it is difficult if not impossible to overheat metals but many metals (such as carbon steels) can become brittle if cooled rapidly. They can also lock in post weld stresses that can compromise the engineering qualities expected. Preheating builds up heat in the metal and it takes longer for it to cool. In affect, preheating is also a portion of the postheating formula. In most welding code applications, carbon steels and some other metals require preheating prior to welding to be in compliance.
Reverse polarity in welding?
Immediate and catastrophic destruction of transistors and/or diodes. While that does not ALWAYS occur, it's certainly possible. Start with the alternator. No doubt those diodes have been destroyed if a battery has been connected with reverse polarity.
For ss welding which electrodes should be used?
This would depend on several variable such as: Welding process being used (SMAW, GMAW, etc). Specific type and grade of the Stainless Steel. The required tensile strength, ductility, and corrosion resistance. If you are welding pressure piping, the applicable ASME codes have a table in section IX. AWS D1.6 addresses structural applications. There are three basic types of Stainless Steels. Austenitic, Martensitic, and ferritic. Each has characteristics that differ from each other in the post welded condition. For a good selection of electrodes and their applications, your local welding supplier should have free reference books by various suppliers that will help. These are the same books we us to assist us in developing welding procedures to various codes and standards.
Which of the following is NOT a post-secondary degree?
Post secondary education is the educational level following the completion of a school providing a secondary education. This would include high school (secondary school). Thus, any degree in higher education following secondary school is considered post secondary, if not then it is not post secondary.
Does AA degree qualify as post secondary education?
yes, and Associates Degree (AA) is part of a post secondary education.
Does law school qualify as post secondary education?
Most certainly it is post secondary education. It is actually considered graduate studies.
What does post secondary education refer to?
Education after high school
What does post-secondary education refer to?
Education after high school
What is a post secondary certificate?
It depends on where the education is being taken and the terminology they use. That being said, post secondary typically refers to education taken after completion of high school. For example, those who pursue a college or university degree are pursuing post secondary school education.
What education do you have to have to be a landscape contractor?
all u need is post secondary education

What is the further education?
Further education is post-secondary school in the UK and Ireland.
Is post secondary degree is equal to master degree?
Post secondary education can be any degree beyond high school completion.
What is another word for graduate school?
Post Secondary Education
