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inspector that performed their duties with due diligence in regards to reviewing welder certifications (probably out of date for the above, if any), welding procedures (if any), approved fabrication drawings (probably hand drawn on a beer napkin), appropriate electrodes and welding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
Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
What is the first pass in a bevel pipe weld?
root pass
What is mean by pass line in cold rolling mill?
The pass line in a cold rolling mill passes through the center of the billet which is on the funace exit rollers and runs through each stand through the shear blades dividing the shear prior to the cooling bed. All of the guide equipment is aligned to the pass line.
What is filling pass in welding?
Filling pass is a welding process which function to filling filler metal inside welding groove before capping process be execute
Welding current for a 3.2mm rod?
The current requirement while welding with 3.2 mm size electrode varies with wether it is root pass or second or capping pass. As for root pass value of current will be () and for 2nd or capping pass its value will be ().
What does 7016 stand for on a welding rod?

Single pass assembler in system software?
input file for the single pass assembler
How much time between welding passes?
It depends on what type of process you are doing, but the average time from the root pass to the hot pass is about 5 to 10 minutes.
What is passed on?
A single pass compiler also known as a one-pass compiler is a compiler that only passes through the code once and doesn't go back. They're faster than a multi-pass compiler but they are very limited in what they can do.
What is single pass?
the weld formed using only one pass
What is elapse meant?
it means to pass or go by time
What is rotpass in welding?
I think you mean root pass. An example would be when butt welding two pieces of plate together (end to end). You would grind a bevel (angle) along the edge of each plate so when you put them end to end there is a small gap between them except at one small point at the bottom. This gap will be filled with molten weld metal to fuse the two plates. Typically, this gap cannot be filled up by one pass with the weld electrode. The welder will go back and forth along the plate eventually filling the entire gap. The "root pass" is simply the first pass the welder makes.
