What does a Welding Inspector do?
A welding inspector spends lots of money getting exam qualifications and then re-sitting the same exams every five years for the privilege of sitting on his a--e at home most of the year waiting on the phone to ring ^^^^ The above was most likely written by an out of work welder (waiting at home for a council call) that became unemployed due to the problems that were encountered by crossing paths with a welding inspector that performed their duties with due diligence in regards to reviewing welder certifications (probably out of date for the above, if any), welding procedures (if any), approved fabrication drawings (probably hand drawn on a beer napkin), appropriate electrodes and welding equipment (chromed dental floss and a hair dryer from Tesco will not be acceptable), proper materials and fit up (scrap iron and rough guesses on dimensions most likely), industry and welding code approved welding practices (unlike the slop normally put in at their own manse and manor), failure to pass visual and non-destructive testing (Seeing through the weld in 3 spots is NOT acceptable in any code, thank you) and a myriad of other failures by the above poster that were easily spotted by the welding inspector. try this instead: http://www.weldmyworld.com/blog/2011/11/what-does-a-certified-welding-inspector-actually-do.html
What is horizontal welding position?
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
How many welding and joining processes are available commercially?
There are numerous commercially available welding and joining processes, with the most common ones including arc welding, MIG (metal inert gas) welding, TIG (tungsten inert gas) welding, resistance welding, and laser welding. Additionally, processes like spot welding, electron beam welding, and friction welding are also widely used in various industries. The choice of process often depends on factors such as the materials being joined, the desired strength of the joint, and production efficiency. Overall, the diversity of welding and joining methods enables tailored solutions for specific applications across different sectors.

What is the difference between welding engineering and welding technology?
Welding technology is the study and application of the many processes of joining various metals. Welding Engineering is a far deeper study and application into the individual characteristics of each metal. A welding engineer will decide what metals are used in a project and what process to weld those metals. Weld techs will usually just receive blue prints and weld as instructed. Welding technology is usually a 2 year degree, and Welding Engineering is a 4+year degree.
What are Hobart welders and what they entail?

Welding procedure specification?
A Welding Procedure Specification (WPS) is a formal document describing http://www.answers.com/topic/welding procedures. According to the http://www.answers.com/topic/american-welding-society-1 (AWS), a WPS provides in detail the required welding variables for specific application to assure http://www.answers.com/topic/repeatability by properly trained http://www.answers.com/topic/welder and welding operators. The American Society For Mechanical Engineers (ASME) similarly defines Welding Procedure Specification (WPS) as a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements.
What tack wlding size and spacing is needed in relationship to material thickness?
The tack welding size and spacing needed for a particular material thickness can vary, but a common guideline is to use tack welds that are approximately 1.5 times the material thickness. The spacing between tack welds should be around 3-4 times the material thickness, depending on the specific welding application and joint configuration. It's always important to refer to welding codes, standards, or consult with a welding engineer for specific recommendations.
What is the difference between pressure and fusion welding?
Pressure welding uses pressure to create the bond between two materials, while fusion welding relies on melting the materials to create the bond. In pressure welding, the materials are pressed together under high pressure, while in fusion welding, the materials are melted together through the application of heat.
How many kgs of welding rod consumed in a linear foot?
The amount of welding rod consumed in a linear foot depends on several factors, including the type of welding process, the size and type of rod used, and the specific joint configuration. Generally, a rough estimate for arc welding can be about 0.5 to 1 kg of welding rod per linear foot. For precise calculations, it's essential to consider the specific application and welding parameters.
What is the weld hardness in welded pipe?
The answer is entirely dependent on the material/s you are welding. Consult ASME for your specific application.
Why must the current be adjusted for a particular welding operation?
The current must be adjusted for a particular welding operation to ensure proper penetration, heat input, and weld quality. Different materials, thicknesses, and welding positions require different levels of current to achieve the desired results. Failure to adjust the current can result in poor weld quality, lack of penetration, or material damage.
How welding can be defined?
welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.
