Welding Certification assessments are numbered by place and joint kind. As an illustration a 1 G signifies a flat place groove weld. The 1 means flat place, and the G signifies a groove weld.
I noticed a video the opposite day that marketed a cellular welding lab that was used to coach and certify welders.
Just a few college students in addition to the trainer have been interviewed and described the 8 weeks of welding coaching that led as much as welding certification assessments within the 1G place.
What?
That is proper, 8 weeks of welding coaching per course of to have the ability to certify in a 1 G weld take a look at.
I do not get it. After 8 weeks of coaching in a welding course of, why cannot the welder go another positions like 3G and 4G welding assessments?
Do you know {that a} 3G plate take a look at mixed with a 4G plate take a look at certifies a welder in ALL positions?
That is all positions. Like 1G , 2G, 3G, and 4G. in addition to each place of fillet welds conceivable too.
A 1G welding take a look at certifies a welder to weld in what number of positions? One ! that is it …only one.
You get much more bang in your buck by coaching welders to certify in each the 3G and 4G positions.
One other problem is that 1G welding assessments sometimes do not have excellent go charges.
You already know why?
Gravity. That is proper., gravity is working in opposition to you and never for you. Gravity lets the slag circulate forward of the arc on a 1G welding take a look at and in case you are not cautious, it might trigger chilly lap and slag inclusions.
Gravity works For you and never in opposition to you on a 3G vertical plate welding take a look at.
Gravity retains the flux behind the arc. The arc is then allowed to do its factor and penetrate into the bottom steel. So long as you preserve sufficient amperage and a decent arc, issues will go nicely on a 3G vertical plate take a look at.
The AWS (American Welding Society) classifies the 1G place welding take a look at as the simplest.
I disagree with that in the case of beveled groove welds.
I consider 2G horizontal and 3G vertical welding certification assessments have higher go charges in the case of a bend take a look at or x ray testing.
